  • SDK support for Document Intelligence API v2.0 Public Preview - This month we expanded our service support to include a preview SDK for Document Intelligence v2.0 release. Use these links to get started with your language of choice:
  • .NET SDK
  • Java SDK
  • Python SDK
  • JavaScript SDK

The new SDK supports all the features of the v2.0 REST API for Document Intelligence. You can share your feedback on the client libraries through the SDK Feedback form.

  • Copy Custom Model You can now copy models between regions and subscriptions using the new Copy Custom Model feature. Before invoking the Copy Custom Model API, you must first obtain authorization to copy into the target resource. This authorization is secured by calling the Copy Authorization operation against the target resource endpoint.

  • Generate a copy authorization REST API.

  • Copy a custom model REST API.

  • Security improvements.

  • Customer-Managed Keys are now available for FormRecognizer. For more information, see Data encryption at rest for Document Intelligence.

  • Use Managed Identities for access to Azure resources with Azure Active Directory. For more information, see Authorize access to managed identities.

March 2020

  • Value types for labeling You can now specify the types of values you're labeling with the Document Intelligence Sample Labeling tool. The following value types and variations are currently supported:
  • string
    • default, no-whitespaces, alphanumeric
  • number
    • default, currency
  • date
    • default, dmy, mdy, ymd
  • time
  • integer

See the Sample Labeling tool guide to learn how to use this feature.

  • Table visualization The Sample Labeling tool now displays tables that were recognized in the document. This feature lets you view recognized and extracted tables from the document before labeling and analyzing. This feature can be toggled on/off using the layers option.

  • The following image is an example of how tables are recognized and extracted:

    Screenshot of table visualization using the Sample Labeling tool.

  • The extracted tables are available in the JSON output under "pageResults".


    Labeling tables isn't supported. If tables are not recognized and extracted automatically, you can only label them as key/value pairs. When labeling tables as key/value pairs, label each cell as a unique value.

  • Extraction enhancements.

  • This release includes extraction enhancements and accuracy improvements, specifically, the capability to label and extract multiple key/value pairs in the same line of text.

  • Sample Labeling tool is now open-source.

  • The Document Intelligence Sample Labeling tool is now available as an open-source project. You can integrate it within your solutions and make customer-specific changes to meet your needs.

  • For more information about the Document Intelligence Sample Labeling tool, review the documentation available on GitHub.

  • TLS 1.2 enforcement.

  • TLS 1.2 is now enforced for all HTTP requests to this service. For more information, see Azure AI services security.

January 2020

This release introduces the Document Intelligence 2.0. In the next sections, you'll find more information about new features, enhancements, and changes.

  • New features

    • Custom model

      • Train with labels You can now train a custom model with manually labeled data. This method results in better-performing models and can produce models that work with complex forms or forms containing values without keys.
      • Asynchronous API You can use async API calls to train with and analyze large data sets and files.
      • TIFF file support You can now train with and extract data from TIFF documents.
      • Extraction accuracy improvements.
    • Prebuilt receipt model

      • Tip amounts You can now extract tip amounts and other handwritten values.
      • Line item extraction You can extract line item values from receipts.
      • Confidence values You can view the model's confidence for each extracted value.
      • Extraction accuracy improvements.
      • Layout extraction You can now use the Layout API to extract text data and table data from your forms.
  • Custom model API changes

    All of the APIs for training and using custom models are renamed, and some synchronous methods are now asynchronous. The following are major changes:

    • The process of training a model is now asynchronous. You initiate training through the /custom/models API call. This call returns an operation ID, which you can pass into custom/models/{modelID} to return the training results.
    • Key/value extraction is now initiated by the /custom/models/{modelID}/analyze API call. This call returns an operation ID, which you can pass into custom/models/{modelID}/analyzeResults/{resultID} to return the extraction results.
    • Operation IDs for the Train operation are now found in the Location header of HTTP responses, not the Operation-Location header.
  • Receipt API changes

    • The APIs for reading sales receipts are renamed.

    • Receipt data extraction is now initiated by the /prebuilt/receipt/analyze API call. This call returns an operation ID, which you can pass into /prebuilt/receipt/analyzeResults/{resultID} to return the extraction results.

  • Output format changes

    • The JSON responses for all API calls have new formats. Some keys and values are added, removed, or renamed. See the quickstarts for examples of the current JSON formats.
