Overview

Introduction

Elis Document Management API allows you to programmatically access and manage your organization's Elis data and account information. The API allows you to do the following:

Configure Elis to suite you needs: select extracted fields
Integrate Elis with other systems: import, export, extensions
Manage your organization, users, workspaces and queues

Elis Document Management builds on top of the formerly used Data Extraction API (or DE API) to extract information from documents.

How Do I Start?

This documentation provides Getting Started tutorial that walks you through making your first API calls to upload a document and export extracted data from Elis.

If in trouble, feel free to contact us at support@rossum.ai.

HTTP and REST

The Elis Document Management API is organized around REST. Our API has predictable, resource-oriented URLs, and uses HTTP response codes to indicate API errors. We use built-in HTTP features, like HTTP authentication and HTTP verbs, which are understood by off-the-shelf HTTP clients.

HTTP Verbs

Call the API using the following standard HTTP methods:

GET to retrieve an object or multiple objects in a specific category
POST to create an object
PUT to modify entire object
PATCH to modify fields of the object
DELETE to delete an object

We support cross-origin resource sharing, allowing you to interact securely with our API from a client-side web application. JSON is returned by API responses, including errors (except when another format is requested, e.g. XML).

Authentication

Most of the API endpoints require user to be authenticated. To login to Elis DM API, post an object with username and password fields. Login returns new authentication key to be used in token authentication.

User may delete a token using logout endpoint or automatically after a configured time (default expire time is 162 hours). Default expire time can be lowered using max_token_lifetime_s field. When token expires, 401 status is returned. Users are expected to re-login to obtain a new token.

Login user using username and password

curl -H 'Content-Type: application/json' \
  -d '{"username": "east-west-trading-co@elis.rossum.ai", "password": "aCo2ohghBo8Oghai"}' \
  'https://api.elis.rossum.ai/v1/auth/login'

{
  "key": "db313f24f5738c8e04635e036ec8a45cdd6d6b03"
}

POST /v1/auth/login

Use token key in requests

curl -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03' \
  'https://api.elis.rossum.ai/v1/organizations/406'

Login user expiring after 1 hour

curl -H 'Content-Type: application/json' \
  -d '{"username": "east-west-trading-co@elis.rossum.ai", "password": "aCo2ohghBo8Oghai", "max_token_lifetime_s": 3600}' \
  'https://api.elis.rossum.ai/v1/auth/login'

{
  "key": "ltcg2p2w7o9vxju313f04rq7lcc4xu2bwso423b3"
}

Response

Status: 200

Returns object with "key", which is an actual authentication token.

Logout

Logout user

curl -X POST -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03' \
  'https://api.elis.rossum.ai/v1/auth/logout'

{
  "detail": "Successfully logged out."
}

POST /v1/auth/logout

Logout user, discard auth token.

Response

Status: 200

Pagination

All object list operations are paged by default, so you may need several API calls to obtain all objects of given type.

Parameter	Default	Maximum	Description
page_size	20	100 (*)	Number of results per page
page	1		Page of results

(*) Maximum page size of annotation list and CSV export is 1000.

Filters and ordering

List queues of workspace 7540, with locale en_US and order results by name.

curl -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03' \
  'https://api.elis.rossum.ai/v1/queues?workspace=7540&locale=en_US&ordering=name'

Lists may be filtered using various attributes. Multiple attributes are combined with AND, which results in more specific response. Please refer to the particular object description.

All filter parameters that refers to object expect only id (instead of URL) of the object.

Ordering of results may be enforced by the ordering parameter and one or more keys delimited by a comma. Preceding key with a minus sign - enforces descending order.

Metadata

Example metadata in a document object

{
  "id": 319768,
  "url": "https://api.elis.rossum.ai/v1/documents/319768",
  "s3_name": "05feca6b90d13e389c31c8fdeb7fea26",
  "annotations": [
    "https://api.elis.rossum.ai/v1/annotations/319668"
  ],
  "mime_type": "application/pdf",
  "arrived_at": "2019-02-11T19:22:33.993427Z",
  "original_file_name": "document.pdf",
  "content": "https://api.elis.rossum.ai/v1/documents/319768/content",
  "metadata": {
    "customer-id": "f205ec8a-5597-4dbb-8d66-5a53ea96cdea",
    "source": "local"
  }
}

When working with API objects, it may be useful to attach some information to the object (e.g. customer id to a document). You can store custom string key-value pairs in a metadata section available in most objects.

List of objects with metadata support: organization, workspace, queue, schema, connector, inbox, document, annotation, page.

Total metadata size may be up to 1 kB per object.

Versioning

API Version is part of the URL, e.g. https://api.elis.rossum.ai/v1/users.

To allow API progress, we consider addition of a field in a JSON object to be a backward-compatible operation that may be introduced at any time. Clients are expected to deal with such changes.

In order to be notified about future API changes and improvements, please subscribe to elis-api-announcements group.

Dates

All dates fields are represented as ISO 8601 formatted strings, e.g. 2018-06-01T21:36:42.223415Z. All returned dates are in UTC timezone.

Errors

Our API uses conventional HTTP response codes to indicate the success or failure of an API request.

Code	Status	Meaning
400	Bad Request	Invalid input data or error from connector.
401	Unauthorized	The username/password is invalid or token is invalid (e.g. expired).
403	Forbidden	Insufficient permission, missing authentication, invalid CSRF token and similar issues.
404	Not Found	Entity not found (e.g. already deleted).
405	Method Not Allowed	You tried to access an endpoint with an invalid method.
409	Conflict	Trying to change annotation not currently assigned or assigned to another user.
413	Payload Too Large	for too large payload (especially for files uploaded).
500	Internal Server Error	We had a problem with the server. Try again later.
503	Service Unavailable	We're temporarily offline for maintenance. Please try again later.

Getting Started

Here you will learn how to authenticate, upload a document and export extracted data. You need curl or similar tool to interact with the API.

Install curl tool

Test curl is installed properly

}

You may also want to install jq tool to make curl output human-readable.

Use API on Windows

This API documentation is written for usage in command line interpreters running on UNIX based operation systems. Windows users may need to use the following substitutions when working with API:

Character used in this documentation	Meaning/usage	Substitute character for Windows users
'	single quotes	"
"	double quotes	"" or \"
\	continue the command on the next line	^

Example of API call on UNIX-based OS

curl -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03' -H 'Content-Type: application/json' \
  -d '{"target_queue": "https://api.elis.rossum.ai/v1/queues/8236", "target_status": "to_review"}' \
  'https://api.elis.rossum.ai/v1/annotations/315777/copy'

Examples of API call on Windows

curl -H "Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03" -H "Content-Type: application/json" ^
  -d "{""target_queue"": ""https://api.elis.rossum.ai/v1/queues/8236"", ""target_status"": ""to_review""}" ^
  "https://api.elis.rossum.ai/v1/annotations/315777/copy"


curl -H "Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03" -H "Content-Type: application/json" ^
  -d "{\"target_queue\": \"https://api.elis.rossum.ai/v1/queues/8236\", \"target_status\": \"to_review\"}" ^
  "https://api.elis.rossum.ai/v1/annotations/315777/copy"

Create an account

In order to interact with the API, you need an account. If you do not have one, you can create one via our self-service portal.

Fill-in your username and password (login credentials to work with API are the same as those to log into your account.). Trigger login endpoint to obtain a key (token), that can be used in subsequent calls.

curl -s -H 'Content-Type: application/json' \
  -d '{"username": "east-west-trading-co@elis.rossum.ai", "password": "aCo2ohghBo8Oghai"}' \
  'https://api.elis.rossum.ai/v1/auth/login'
{"key": "db313f24f5738c8e04635e036ec8a45cdd6d6b03"}

This key will be valid for a default expire time (currently 162 hours) or until you log out from the sessions.

Upload a document

In order to upload a document (PDF or image) through the API, you need to obtain the id of a queue first.

curl -s -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03'
  'https://api.elis.rossum.ai/v1/queues?page_size=1' | jq -r .results[0].url
https://api.elis.rossum.ai/v1/queues/8199

Then you can upload document to the queue. Alternatively, you can send documents to a queue-related inbox. See upload for more information about importing files.

curl -s -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03' \
  -F content=@document.pdf 'https://api.elis.rossum.ai/v1/queues/8199/upload' | jq -r .results[0].annotation
https://api.elis.rossum.ai/v1/annotations/319668

Wait for document to be ready and review extracted data

As soon as a document is uploaded, it will show up in the queue and the data extraction will begin. It may take a few seconds to several minutes to process a document. You can check status of the annotation and wait until its status is changed to to_review.

curl -s -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03' \
  'https://api.elis.rossum.ai/v1/annotations/319668' | jq .status
"to_review"

After that, you can open the Elis web interface elis.rossum.ai to review and confirm extracted data.

Download reviewed data

Now you can export extracted data using the export endpoint of the queue. You can select XML, CSV or JSON format. For CSV, use URL like:

curl -s -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03' \
  'https://api.elis.rossum.ai/v1/queues/8199/export?status=exported&format=csv&id=319668'
Invoice number,Invoice Date,PO Number,Due date,Vendor name,Vendor ID,Customer name,Customer ID,Total amount,
2183760194,2018-06-08,PO2231233,2018-06-08,Alza.cz a.s.,02231233,Rossum,05222322,500.00

Logout

Finally you can dispose token safely using logout endpoint:

curl -s -X POST -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03' \
  'https://api.elis.rossum.ai/v1/auth/logout'
{"detail":"Successfully logged out."}

Import and Export

Documents may be imported into Elis using the REST API and email gateway. Supported file formats are PDF, PNG, and JPEG.

In order to get the best results from Elis the documents should be in A4 format of at least 150 DPI (in case of scans/photos).

Upload

You can upload a document to the queue using upload endpoint with one or more files to be uploaded. As soon as a document is uploaded, data extraction is started.

Upload endpoint supports basic authentication to enable easy integration with third-party systems.

Import by Email

It is also possible to send documents by email using a properly configured inbox that is associated with a queue. Users then only need to know the email address to forward emails to.

For every incoming email, Elis extracts PDF documents and images, stores them in the queue and starts data extraction process.

Small images (up to 100x100 pixels) are ignored, see inbox for reference.

Export

In order to export extracted and confirmed data you can call export endpoint. You can specify status, time-range filters and annotation id list to limit returned results.

Upload endpoint supports basic authentication to enable easy integration with third-party systems.

Auto-split of document

It is possible to process a single PDF file that contains several invoices. Just insert a special separator page between the documents. You can print this page and insert it between documents while scanning.

Elis will recognize a QR code on the page and split the PDF into individual documents automatically. Produced documents are imported to the queue, while the original document is set to a split state.

Usage report

In order to obtain an overview of the Elis usage, you can download Excel file with basic Elis statistics.

The statistics contains following attributes:

Username (may be empty in case document was not modified by any user)
Workspace name
Queue name
Imported: count of all documents that were imported during the time period
Deleted: count of documents that were deleted during the time period
Exported: count of documents that were successfully exported during the time period
Net time: total time spent by a user validating the successfully exported documents

Download usage statistics (January 2019).

curl -H 'Authorization: token db313f24f5738c8e04635e036ec8a45cdd6d6b03' \
  'https://api.elis.rossum.ai/manage/usage-report?from=2019-01-01&to=2019-01-31'

Excel file (xlsx) may be downloaded from https://api.elis.rossum.ai/manage/usage-report.

You may specify date range using from and to parameters (inclusive). If not specified, a report for last 12 months is generated.

Document Schema

Every queue has an associated schema that specifies which fields will be extracted from documents as well as the structure of the data sent to connector. Elis schema supports single datapoints (datapoint), lists of datapoints of the same type (multivalue) or tuples (tuple). At the topmost level, each schema consists of sections, which may either directly contain actual data (datapoints) or use nested multivalues and tuples as containers for single datapoints.

Schema content

Schema content consists of a list of section objects.

Common attributes

The following attributes are common for all schema objects:

Attribute	Type	Description	Required
category	string	Category of an object, one of `section`, `multivalue`, `tuple` or `datapoint`.	yes
id	string	Unique identifier of an object.	yes
label	string	User-friendly label for an object, shown in the user interface	yes

Section

Example of a section:

{
    "category": "section",
    "id": "amounts_section",
    "label": "Amounts",
    "children": [...],
    "icon": ""
}

Section represents a logical part of the document, such as amounts or vendor info. It is allowed only at the top level. Schema allows mutiple sections, and there should be at least one section in the schema.

Attribute	Type	Description	Required
children	list[object]	Specifies objects grouped under a given section. It can contain `multivalue` or `datapoint` objects.	yes
icon	string	The icon that appears on the left panel in the UI for a given section (not yet supported on UI).

Datapoint

Example of a datapoint:

{
    "category": "datapoint",
    "id": "invoice_id",
    "label": "Invoice ID",
    "type": "string",
    "default_value": null,
    "rir_field_names": ["invoice_id"],
    "width_chars": 10,
    "constraints": {
        "length": {
            "exact": null,
            "max": 16,
            "min": null
        },
        "regexp": {
            "pattern": ""
        },
        "required": false
    }
}

Datapoint represents single value, typically a field of a document or some global document information.

Attribute	Type	Description	Required
type	string	Data type of the object, must be one of the following: `string`, `number`, `date`, `enum`	yes
rir_field_names	list[string]	List of names used to initialize content from DE API predictions. If specified, the value of the first extracted field from the array is used, otherwise, no DE API initialization is done for the object.
default_value	string	Default value used either for fields that do not use hints from DE API predictions (i.e. `rir_field_names` are not specified), or DE API does not return any data for the field.
format	string	Enforces a format for `date` or `number` datapoint on the UI. See Date format and Number format.
constraints	object	A map of various constraints for the field. See Value constraints.
options	object	Attribute to specify available options. Only allowed for `enum` data type. See Enum options.
width_chars	integer	Expected width of content in characters. The client uses this attribute to create appropriate space for the content. Currently not supported in UI.
score_threshold	float [0;1]	Threshold used to validate field content by scores obtained from DE API prediction. These scores represents how confident the model is that the actual result is correct. It may be used to automate validation.
hidden	boolean	If set to `true`, the datapoint is not visible in the user interface, but remains stored in the database.

Date format

Example number format specification

{
  "id": "item_quantity",
  "type": "number",
  "label": "Quantity",
  "format": "#,##0.#",
  "category": "datapoint",
  ...
}

Example enum datapoint with options

{
  "id": "document_type",
  "type": "enum",
  "label": "Document type",
  "hidden": false,
  "category": "datapoint",
  "options": [
    {
      "label": "Invoice Received",
      "value": "21"
    },
    {
      "label": "Invoice Sent",
      "value": "22"
    },
    {
      "label": "Receipt",
      "value": "23"
    }
  ],
  "width_chars": 10,
  "default_value": "21",
  "rir_field_names": []
}

Example value constraints

  "id": "invoice_id",
  "type": "string",
  "label": "Invoice ID",
  "category": "datapoint",
  "constraints": {
    "length": {
      "max": 32,
      "min": 5
    },
    "required": false
  },
  "width_chars": 10,
  "default_value": null,
  "rir_field_names": [
    "invoice_id"
  ]
}

Date format supported: available tokens

Example date formats:

D/M/YYYY: e.g. 23/1/2019
MM/DD/YYYY: e.g. 01/23/2019
YYYY-MM-DD: e.g. 2019-01-23 (ISO date format)

Number format

For number data type, available format choices are # ##0,#, # ##0.#, #,##0.# and null. Default is # ##0.#.

Enum options

Specifies list of available options. Every option consists of an object with keys:

Attribute	Type	Description	Required
value	string	Value of the option.	yes
label	string	User-friendly label for the option, shown in the UI.	yes

Value constraints

Constraints limit allowed values. When constraints is not satisfied, annotation is considered invalid and cannot be exported.

Attribute	Type	Description
length	object	Defines minimum, maximum or exact length for the datapoint value. By default, minimum and maximum are `0` and infinity, respectively. Supported attributes: `min`, `max` and `exact`
regexp	object	When specified, content must match a regular expression. Supported attributes: `pattern`
required	boolean	Specifies if the datapoint is required by the schema. Default value is `true`.

Multivalue

Example of a multivalue:

{
  "category": "multivalue",
  "id": "line_item",
  "label": "Line Item",
  "children": {
    ...
  },
  "min_occurrences": null,
  "max_occurrences": null
}

Multivalue is list of datapoints or tuples of the same type. It represents a container for data with multiple occurrences (such as line items) and can contain only objects with the same id.

Attribute	Type	Description	Required
children	object	Object specifying type of children. It can contain only objects with categories `tuple` or `datapoint`.	yes
min_occurrences	integer	Minimum number of occurrences of nested objects. Minimum required value for the field is 0. If not specified, it is set to 0 by default.
max_occurrences	integer	Maximum number of occurrences of nested objects. Minimum required value for the field is 1. If not specified, it is set to infinity by default.

Tuple

Example of a tuple:

{
  "category": "tuple",
  "id": "tax_details",
  "label": "Tax Details",
  "children": [
    ...
  ],
  "rir_field_names": [
    "tax_details"
  ]
}

Container representing tabular data with related values, such as tax details. A tuple must be nested within a multivalue object, but unlike multivalue, it may consist of objects with different ids.

Attribute	Type	Description	Required
children	list[object]	Array specifying objects that belong to a given `tuple`. It can contain only objects with category `datapoint`.	yes
rir_field_names	list[string]	List of names used to initialize content from DE API predictions. If specified, the value of the first extracted field from the array is used, otherwise, no DE API initialization is done for the object.

Updating Schema

When project evolves, it is a common practice to enhance or change extracted field set. This is done by creating new schema object and linking it to the queue (replacing previous schema object).

Elis supports multiple schema versions at the same time. Every annotation has a related schema that describes its shape and fields. This schema is linked to the annotation as soon as annotation is created or when it is opened in the verification UI. When queue schema object is replaced, annotation data is re-shaped and updated to match to match current queue's schema.

In order to transfer annotation field values properly during the schema update, a datapoint's category and schema_id must be preserved.

Supported operations that preserve fields data are:

adding a new datapoint (filled from Data Extractor, if available)
reordering datapoints on the same level
moving datapoints from section to another section
moving datapoints to and from a tuple
reordering datapoints inside a tuple
making datapoint a multivalue (original datapoint is the only value in a new multivalue container)
making datapoint non-multivalue (only first datapoint value is preserved)

Extracted field types

DE API currently automatically extracts the following fields at the all endpoint, subject to ongoing expansion.

Identifiers

Example of a schema with different identifiers:

[
  {
    "category": "section",
    "children": [
      {
        "category": "datapoint",
        "constraints": {
          "required": false
        },
        "default_value": null,
        "id": "invoice_id",
        "label": "Invoice number",
        "rir_field_names": [
          "invoice_id"
        ],
        "type": "string",
        "width_chars": 10
      },
      {
        "category": "datapoint",
        "constraints": {
          "required": false
        },
        "default_value": null,
        "format": "D/M/YYYY",
        "id": "date_issue",
        "label": "Issue date",
        "rir_field_names": [
          "date_issue"
        ],
        "type": "date",
        "width_chars": 10
      },
      {
        "category": "datapoint",

          "terms"
        ],
        "type": "string",
        "width_chars": 10
      }
    ],
    "icon": null,

DE API currently automatically extracts line item table content and recognizes row and column types as detailed below. Invoice line items come in a wide variety of different shapes and forms. The current implementation can deal with (or learn) most layouts, with borders or not, different spacings, header rows, etc. We currently make two further assumptions:

The table generally follows a grid structure - that is, columns and rows may be represented as rectangle spans. In practice, this means that we may currently cut off text that overlaps from one cell to the next column. We are also not optimizing for table rows that are wrapped to multiple physical lines.
The table contains just a flat structure of line items, without subsection headers, nested tables, etc.

We plan to gradually remove both assumptions in the future.

Attribute rir_field_names	Field label	Description
table_column_code	Item Code/Id	Can be the SKU, EAN, a custom code (string of letters/numbers) or even just the line number.
table_column_description	Item Description	Line item description. Can be multi-line with details.
table_column_quantity	Item Quantity	Quantity of the item.
table_column_uom	Item Unit of Measure	Unit of measure of the item (kg, container, piece, gallon, ...).
table_column_rate	Item Rate	Tax rate for the line item.
table_column_tax	Item Tax	Tax amount for the line. Rule of thumb: `tax = rate * amount_base`.
table_column_amount	Amount	Unit price with tax. Rule of thumb: `amount = amount_base + tax`.
table_column_amount_base	Amount Base	Unit price without tax.
table_column_amount_total	Amount Total	The total amount to be paid for all the items including the tax. Rule of thumb: `amount_total = amount * quantity`.
table_column_amount_total_base	Amount Total Base	The total amount to be paid for all the items excluding the tax. Rule of thumb: `amount_total_base = amount_base * quantity`.
table_column_other	Other	Unrecognized data type.

Document Lifecycle

Each document is submitted to Elis within a given queue. Then it goes through a variety of states as it is processed, and eventually exported.

State	Description
importing	Document is being processed by a neural network data extraction; initial state of the document.
failed_import	Import failed e.g. due to a malformed document file.
to_review	Initial extraction step is done and the document is waiting for user verification.
reviewing	Document is undergoing verification in the user interface.
postponed	Operator has chosen to postpone the document instead of exporting it.
exporting	Document is verified and is awaiting the connector export call.
exported	Document was exported through the connector; this is the typical terminal state of a document.
failed_export	When the connector returned an error.
deleted	When the document was deleted by the user.
purged	Only metadata was preserved after a deletion.

Extensions

Elis DM may be extended by integration of third-party services. Currently we support Connector extension type. We will build on connector functionality and generalize extensions in the future.

Connector Extension

The connector component typically takes care of integration of Elis with client systems that are to receive processed documents. It is called when a document is finally exported and it is also possible to hook it elsewhere in the process - particularly receiving on-the-fly verification callbacks e.g. for supplier matching or other customization purposes.

Connector is designed to be implemented using a push-model using common HTTPS protocol. When annotation data is changed, or when data export is triggered, specific connector endpoint is called with annotation data as a request payload.

Setup a connector

In Elis, a connector object defines service_url and params for construction of HTTPS requests and authorization_token that is passed in every request to authenticate the caller as the actual Elis server. It may also uniquely identify the organization when multiple Elis organizations share the same connector server.

The authorization token is passed as an Authorizaton HTTP header: Authorization secret_key {authorization_token}

To set-up a connector for a queue, create a connector object with URL of the remote.

Connector may be related to one or more queues.

}

All connector endpoints, representing hooks at particular points in the document lifetime, are simple verbs that receive a JSON POSTed and potentially expect a JSON returned in turn.

Errors

If a connector does not implement an endpoint, it may return HTTP status 404. An endpoint may fail, returning either HTTP 4xx or HTTP 5xx; for some hooks (like validate and save), this may trigger a user interface message; either the error key of a JSON response is used, or the response body itself in case it is not JSON. The connector hook save can be called in asynchronous (default) as well as synchronous mode (useful for embedded mode).

Data format

The received JSON object contains two keys, meta carrying the metadata and content carrying endpoint-specific content.

The metadata identify the concerned document, containing attributes:

Key	Type	Description
document_url	URL	document URL
arrived_at	timestamp	A time of document arrival in Elis (ISO 8601)
original_file	URL	Permanent URL for the document original file
original_filename	string	Filename of the document on arrival in Elis
queue_name	string	Name of the document's queue
workspace_name	string	Name of the document's workspace
organization_name	string	Name of the document's organization
annotation	URL	Annotation URL
queue	URL	Document's queue URL
workspace	URL	Document's workspace URL
organization	URL	Document's organization URL
modifier	URL	Modifier URL

A common class of content is the annotation tree, which is a JSON object that can contain nested datapoint objects, and matches the schema datapoint tree.

Intermediate nodes have the following structure:

Key	Type	Description
id	integer	A unique id of the given node
schema_id	string	Reference mapping the node to the schema tree
category	string	One of section, multivalue, tuple
content	list	A list of other nodes

Datapoint (leaf) nodes structure contains actual data:

Key	Type	Description
id	integer	A unique id of the given node
schema_id	string	Reference mapping the node to the schema tree
category	string	datapoint
type	string	One of string, date or number, as specified in the schema
value	string	The datapoint value, string represented but normalizes, to that they are machine readable: ISO format for dates, a decimal for numbers
page	integer	A 1-based integer index of the page, optional
position	[float]	List of four floats describing the x1, y1, x2, y2 bounding box coordinates

Note that for both meta and content the set of keys returned is subject to extension.

Hook: validate

This hook is called after operator updates a field in the Elis verification interface.

It may:

validate the given annotation tree and return a list of messages commenting on it (e.g. pointing out errors or showing matched suppliers).
update the annotation tree by returning a list of datapoints to update.

Both the messages and the updated datapoints are shown in the verification interface. Moreover, the messages may block export in the case of errors. This hook should be fast as it is part of an interactive workflow.

Receives an annotation tree as content.

Example of validate response

{
  "messages": [
    {
      "content": "Invalid invoice number format",
      "id": "197467",
      "type": "error"
    }
  ],
  "updated_datapoints": [
    {
      "id": "198142",
      "value": "1532.00"
    }
  ]
}

Returns a JSON object with two lists: messages (required) and updated_datapoints (optional).

The message object contains attributes:

For example, you may use error for fatals like a missing required field, whereas info is suitable to decorate a supplier company id with its name as looked up in the suppliers database.

The updated datapoint object contains attributes:

Key | Type | Description ---------------------+----------------- id | string | A unique id of the concerned datapoint, currently only datapoints of category datapoint can be updated value | string | New value of the datapoint. Value is formatted according to the datapoint type (e.g. date is string representation of ISO 8601 format). hidden | boolean | Toggle for hiding/showing of the datapoint, see datapoint options | [object] | Options of the datapoint -- valid only for type=enum, see enum options position | [float] | New position of the datapoint, list of four numbers.

Validate endpoint should always return 200 OK status.

An error message returned from the connector prevents user from exporting the document.

The hook is also called when document processing has finished (on importing => to_review status change). It may be used to update or enhance annotation data before user starts to validate the document. This initial validate hook is marked with initial=true URL parameter.

Hook: save

This hook is called when the invoice transitions to the exporting state. Connector may process the final document annotation and save it to the target system. It receives an annotation tree as content.

The save hook is called asynchronously (unless synchronous mode is set in related connector object. Timeout of the save hook endpoint is 60 seconds.

It should return an empty response with 204 No Content status for success.

For graceful failure with error message return 422 Unprocessable Entity or 500 Internal Server Error status with response with same format as in validate hook. If the hook fails with an HTTP error, the document transitions to the failed_export state and is available to the operators for review.

Embedded Mode

In some use-cases, it is desirable to use only annotation-related functionality of the Elis document management interface. Elis may be integrated with other systems using so-called embedded mode.

In embedded mode, special URL is constructed and then used in iframe or popup browser window to show Elis annotation view. Some view navigation widgets are hidden (such as home, postpone and delete buttons), so that user is only allowed to update and confirm all field values.

Embedded mode workflow

The host application first uploads a document using standard Elis document management API. During this process, an annotation object is created. It is possible to obtain a status of the annotation object and wait for the status to became to_review (ready for checking) using annotation endpoint.

As soon as importing of the annotation object has finished, an authenticated user may call start_embedded endpoint to obtain a URL that is to be included in iframe or popup browser window of the host application. Parameters of the call are return_url and cancel_url that are used to redirect to in a browser when user finishes the annotation.

The URL contains security token that is used by embedded Elis application to access Elis document management API. When the checking of the document has finished, user clicks on done button and host application is notified about finished annotation through save endpoint of the connector HTTP API. By default, this call is made asynchronously, which causes a lag (up to a few seconds) between the click on done button and the call to save endpoint. However, it is possible to switch the calls to synchronous mode by switching the connector asynchronous toggle to false (see connector for reference).

    },
    ...
  ]
}

In order to decrease the number of requests necessary for obtaining useful information about annotations, modifiers and documents can be sideloaded using query parameter sideload. This parameter accepts comma-separated list of keywords: modifiers, documents. Then the response is enriched by the requested keys, which contain lists of the sideloaded objects.

Annotation data is used by the Elis UI to display annotation data properly. Be aware that values are not normalized (e.g. numbers, dates) and data structure may be changed to accommodate UI requirements.

Top level content contains a list of section objects. results is currently a copy of content and is deprecated.

Section objects:

Attribute	Type	Description	Read-only
id	int	A unique ID of a given section.	true
url	URL	URL of the section.	true
category	string	`section`

children	list	Array specifying child objects. Only available for `multivalue` and `tuple` categories.	true
content	dict	A dictionary of the attributes of a given datapoint.	true
value	string	The extracted data of a given node.
page	int	Number of page where the data is situated (see position).
position	list	List of the coordinates of the label box of the given node.
rir_text	string	The extracted text, used as a reference for data extraction models.	true
connector_text	string	Text set by the connector.	true

PATCH /v1/annotations/{id}/content/{id of the child node}

A patch of the annotation data can be used as a provisional substitute feature for sending feedback on incorrectly extracted data. This process is done also during the verification process in an Elis account automatically. Clients or integrators who are not using Elis interface for the verification process but would like to send feedback to this API on the incorrectly extracted data, can integrate the following process to their programs:

start the annotation. start only works for the annotations with one of the following statuses: to_review, reviewing and postponed.
patch the annotation with the right data. Only value, position (and page if relevant) attributes should be sent in the request. (Note: To find the right annotation node more easily, you can refer to the schema_id attribute of the node to filter the correct object.)
confirm the annotation.

In case you would like to cancel the changes, cancel the annotation. The annotation will be reset to the status to_review or postponed, depending on the status it had had when start was called.

Response

Status: 200

Returns updated annotation data for the given node.

Page

Example page object

{
  "id": 558598,
  "annotation": "https://api.elis.rossum.ai/v1/annotations/314528",
  "number": 1,
  "rotation_deg": 0,

  "content": "https://api.elis.rossum.ai/v1/pages/558598/content",
  "metadata": {}
}

A page object contains information about one page of the annotation (we render pages separately for every annotation, but this will change in the future).

Page objects are created automatically during document import and cannot be created through the API, you need to use queue upload endpoint. Pages cannot be deleted directly -- they are deleted on parent annotation delete.

Attribute	Type	Default	Description	Read-only
id	integer		Id of the page	true
url	URL		URL of the page.	true
annotation	URL		Annotation that page belongs to.
number	integer		Page index, first page has index 1.
rotation_deg	integer		Page rotation.
mime_type	string		MIME type of the page (`image/png`).	true
s3_name	string		Internal	true
content	URL		Link to the page raw content (pdf file).
metadata	object	`{}`	Client data, see metadata.
