Use Document Intelligence SDK in your applications

The Document Intelligence SDK enables the use and management of the Document Intelligence service in your application. The SDK builds on the underlying Document Intelligence REST API allowing you to easily use those APIs within your programming language paradigm. Here's how you use the Document Intelligence SDK for your preferred language:

1. Install the SDK client library

C#/.NET

dotnet add package Azure.AI.FormRecognizer --version 4.0.0

Install-Package Azure.AI.FormRecognizer -Version 4.0.0

Java

<dependency>
<groupId>com.azure</groupId>
<artifactId>azure-ai-formrecognizer</artifactId>
<version>4.0.6</version>
</dependency>

implementation("com.azure:azure-ai-formrecognizer:4.0.6")

JavaScript

npm i @azure/ai-form-recognizer@4.0.0

Python

pip install azure-ai-formrecognizer==3.2.0

2. Import the SDK client library into your application

C#/.NET

using Azure;
using Azure.AI.FormRecognizer.DocumentAnalysis;

Java

import com.azure.ai.formrecognizer.*;
import com.azure.ai.formrecognizer.models.*;
import com.azure.ai.formrecognizer.DocumentAnalysisClient.*;

import com.azure.core.credential.AzureKeyCredential;

JavaScript

const { AzureKeyCredential, DocumentAnalysisClient } = require("@azure/ai-form-recognizer");

Python

from azure.ai.formrecognizer import DocumentAnalysisClient
from azure.core.credentials import AzureKeyCredential

3. Set up authentication

There are two supported methods for authentication

• Use a Document Intelligence API key with AzureKeyCredential from azure.core.credentials.

• Use a token credential from azure-identity to authenticate with Azure Active Directory.

Use your API key

Here's where to find your Document Intelligence API key in the Azure portal:

C#/.NET

//set `<your-endpoint>` and `<your-key>` variables with the values from the Azure portal to create your `AzureKeyCredential` and `DocumentAnalysisClient` instance
string key = "<your-key>";
string endpoint = "<your-endpoint>";
AzureKeyCredential credential = new AzureKeyCredential(key);
DocumentAnalysisClient client = new DocumentAnalysisClient(new Uri(endpoint), credential);

Java

// create your `DocumentAnalysisClient` instance and `AzureKeyCredential` variable
DocumentAnalysisClient client = new DocumentAnalysisClientBuilder()
            .credential(new AzureKeyCredential("<your-key>"))
            .endpoint("<your-endpoint>")
            .buildClient();

JavaScript

// create your `DocumentAnalysisClient` instance and `AzureKeyCredential` variable
async function main() {
    const client = new DocumentAnalysisClient("<your-endpoint>", new AzureKeyCredential("<your-key>"));

Python

# create your `DocumentAnalysisClient` instance and `AzureKeyCredential` variable
    document_analysis_client = DocumentAnalysisClient(endpoint="<your-endpoint>", credential=AzureKeyCredential("<your-key>"))

Use an Azure Active Directory (Azure AD) token credential

Note

Regional endpoints do not support AAD authentication. Create a custom subdomain for your resource in order to use this type of authentication.

Authorization is easiest using the DefaultAzureCredential. It provides a default token credential, based upon the running environment, capable of handling most Azure authentication scenarios.

C#/.NET

Here's how to acquire and use the DefaultAzureCredential for .NET applications:

1. Install the Azure Identity library for .NET:

       dotnet add package Azure.Identity
   

       Install-Package Azure.Identity
   

2. Register an Azure AD application and create a new service principal.

3. Grant access to Document Intelligence by assigning the Cognitive Services User role to your service principal.

4. Set the values of the client ID, tenant ID, and client secret in the Azure AD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, and AZURE_CLIENT_SECRET, respectively.

5. Create your DocumentAnalysisClient instance including the DefaultAzureCredential:

   string endpoint = "<your-endpoint>";
   var client = new DocumentAnalysisClient(new Uri(endpoint), new DefaultAzureCredential());
   

For more information, see Authenticate the client

Java

Here's how to acquire and use the DefaultAzureCredential for Java applications:

1. Install the Azure Identity library for Java:

   <dependency>
       <groupId>com.azure</groupId>
       <artifactId>azure-identity</artifactId>
       <version>1.5.3</version>
   </dependency>
   

2. Register an Azure AD application and create a new service principal.

3. Grant access to Document Intelligence by assigning the Cognitive Services User role to your service principal.

4. Set the values of the client ID, tenant ID, and client secret of the Azure AD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, and AZURE_CLIENT_SECRET, respectively.

5. Create your DocumentAnalysisClient instance and TokenCredential variable:

   TokenCredential credential = new DefaultAzureCredentialBuilder().build();
   DocumentAnalysisClient documentAnalysisClient = new DocumentAnalysisClientBuilder()
       .endpoint("{your-endpoint}")
       .credential(credential)
       .buildClient();

JavaScript

Here's how to acquire and use the DefaultAzureCredential for JavaScript applications:

1. Install the Azure Identity library for JavaScript:

   npm install @azure/identity
   

2. Register an Azure AD application and create a new service principal.

3. Grant access to Document Intelligence by assigning the Cognitive Services User role to your service principal.

4. Set the values of the client ID, tenant ID, and client secret of the Azure AD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, and AZURE_CLIENT_SECRET, respectively.

5. Create your DocumentAnalysisClient instance including the DefaultAzureCredential:

   const { DocumentAnalysisClient } = require("@azure/ai-form-recognizer");
   const { DefaultAzureCredential } = require("@azure/identity");
   
   const client = new DocumentAnalysisClient("<your-endpoint>", new DefaultAzureCredential());
   

For more information, see Create and authenticate a client.

Python

Here's how to acquire and use the DefaultAzureCredential for Python applications.

1. Install the Azure Identity library for Python:

   pip install azure-identity
   

2. Register an Azure AD application and create a new service principal.

3. Grant access to Document Intelligence by assigning the Cognitive Services User role to your service principal.

4. Set the values of the client ID, tenant ID, and client secret of the Azure AD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, and AZURE_CLIENT_SECRET, respectively.

5. Create your DocumentAnalysisClient instance including the DefaultAzureCredential:

   from azure.identity import DefaultAzureCredential
   from azure.ai.formrecognizer import DocumentAnalysisClient
   
   credential = DefaultAzureCredential()
   document_analysis_client = DocumentAnalysisClient(
       endpoint="https://<my-custom-subdomain>.cognitiveservices.azure.com/",
       credential=credential
   )

4. Build your application

Create a client object to interact with the Document Intelligence SDK, and then call methods on that client object to interact with the service. The SDKs provide both synchronous and asynchronous methods. For more insight, try a quickstart in a language of your choice.
