Azure Text Translation is a cloud-based REST API feature of the Azure AI Translator service. The Text Translation API enables quick and accurate source-to-target text translations in real time. The Text Translation software development kit (SDK) is a set of libraries and tools that enable you to easily integrate Text Translation REST API capabilities into your applications. Text Translation SDK is available across programming platforms in C#/.NET, Java, JavaScript, and Python.

Supported languages

Text Translation SDK supports the programming languages and platforms:

Language → SDK version	Package	Client library	Supported API version
.NET/C# → 1.0.0	NuGet	Azure SDK for .NET	Translator v3.0

Use Text Translation SDK in your applications

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

1. Install the SDK client library

dotnet add package Azure.AI.Translation.Text --version 1.0.0-beta.1

Install-Package Azure.AI.Translation.Text -Version 1.0.0-beta.1

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-ai-translation-text</artifactId>
    <version>1.0.0-beta.1</version>
</dependency>

implementation("com.azure:azure-ai-translation-text:1.0.0-beta.1")

npm i @azure-rest/ai-translation-text@1.0.0-beta.1

pip install azure-ai-translation-text==1.0.0b1

2. Import the SDK client library into your application

using Azure;
using Azure.AI.Translation.Text;

import java.util.List;
import java.util.ArrayList;
import com.azure.ai.translation.text.models.*;
import com.azure.ai.translation.text.TextTranslationClientBuilder;
import com.azure.ai.translation.text.TextTranslationClient;

import com.azure.core.credential.AzureKeyCredential;

const {TextTranslationClient } = require("@azure-rest/ai-translation-text").default;

from azure.core.credentials import AzureKeyCredential
from azure.ai.translation.text import TextTranslationClient

3. Authenticate the client

Interaction with the Translator service using the client library begins with creating an instance of the TextTranslationClientclass. You need your API key and region to instantiate a client object. The Text Translation API key is found in the Azure portal:

Using a regional endpoint


Uri endpoint = new("<your-endpoint>");
string key = "<your-key>";
string region = "<region>";

AzureKeyCredential credential = new(key);
TextTranslationClient client = new(credential, region);

Using a regional endpoint

String apiKey = "<your-key>";
String endpoint = "<your-endpoint>";
String region = "<region>";

AzureKeyCredential credential = new AzureKeyCredential(apiKey);

TextTranslationClient client = new TextTranslationClientBuilder()
.credential(credential)
.region(region)
.endpoint(endpoint)
.buildClient();


const TextTranslationClient = require("@azure-rest/ai-translation-text").default,

const apiKey = "<your-key>";
const endpoint = "<your-endpoint>";
const region = "<region>";


from azure.ai.translation.text import TextTranslationClient, TranslatorCredential
from azure.ai.translation.text.models import InputTextItem
from azure.core.exceptions import HttpResponseError

key = "<your-key>"
endpoint = "<your-endpoint>"
region = "<region>"


credential = TranslatorCredential(key, region)
text_translator = TextTranslationClient(endpoint=endpoint, credential=credential)

4. Build your application

Create a client object to interact with the Text Translation 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, see the Text Translation sample repository for .NET/C#.
