Package com.azure.ai.formrecognizer

Class FormRecognizerClient

java.lang.Object
com.azure.ai.formrecognizer.FormRecognizerClient
public final class FormRecognizerClient extends Object

This class provides an synchronous client to connect to the Form Recognizer Azure Cognitive Service.

This client provides synchronous methods to perform:

  1. Custom Form Analysis: Extraction and analysis of data from forms and documents specific to distinct business data and use cases. Use the custom trained model by passing its modelId into the beginRecognizeCustomForms method.
  2. Prebuilt Model Analysis: Analyze receipts, business cards, invoices and other documents with supported prebuilt models Use the beginRecognizeReceipts method to recognize receipt information.
  3. Layout Analysis: Extraction and analysis of text, selection marks, tables, and bounding box coordinates, from forms and documents. Use beginRecognizeContent method tpo perform layout analysis.
  4. Polling and Callbacks: It includes mechanisms for polling the service to check the status of an analysis operation or registering callbacks to receive notifications when the analysis is complete.

Refer to the Migration guide to use API versions 2022-08-31 and up.

Service clients are the point of interaction for developers to use Azure Form Recognizer. FormRecognizerClient is the synchronous service client and FormRecognizerAsyncClient is the asynchronous service client. The examples shown in this document use a credential object named DefaultAzureCredential for authentication, which is appropriate for most scenarios, including local development and production environments. Additionally, we recommend using managed identity for authentication in production environments. You can find more information on different ways of authenticating and their corresponding credential types in the Azure Identity documentation".

Sample: Construct a FormRecognizerClient with DefaultAzureCredential

The following code sample demonstrates the creation of a FormRecognizerClient, using the `DefaultAzureCredentialBuilder` to configure it.

 FormRecognizerClient formRecognizerClient = new FormRecognizerClientBuilder()
     .endpoint("{endpoint}")
     .credential(new DefaultAzureCredentialBuilder().build())
     .buildClient();

Further, see the code sample below to use AzureKeyCredential for client creation.

 FormRecognizerClient formRecognizerClient = new FormRecognizerClientBuilder()
     .credential(new AzureKeyCredential("{key}"))
     .endpoint("{endpoint}")
     .buildClient();

      Throws:
      FormRecognizerException - If recognize operation fails and the AnalyzeOperationResult returned with an OperationStatus.FAILED.
      NullPointerException - If identityDocumentUrl is null.
