Create a Translator resource

In this article, you learn how to create a Translator resource in the Azure portal. Azure AI Translator is a cloud-based machine translation service that is part of the Azure AI services family. Azure resources are instances of services that you create. All API requests to Azure AI services require an endpoint URL and a read-only key for authenticating access.


To get started, you need an active Azure account. If you don't have one, you can create a free 12-month subscription.

Create your resource

With your Azure account, you can access the Translator service through two different resource types:

  • Single-service resource types enable access to a single service API key and endpoint.

  • Multi-service resource types enable access to multiple Azure AI services by using a single API key and endpoint.

Complete your project and instance details

After you decide which resource type you want use to access the Translator service, you can enter the details for your project and instance.

  1. Subscription. Select one of your available Azure subscriptions.

  2. Resource Group. You can create a new resource group or add your resource to a pre-existing resource group that shares the same lifecycle, permissions, and policies.

  3. Resource Region. Choose Global unless your business or application requires a specific region. If you're planning on using the Document Translation feature with managed identity authorization, choose a geographic region such as East US.

  4. Name. Enter a name for your resource. The name you choose must be unique within Azure.


    If you're using a Translator feature that requires a custom domain endpoint, such as Document Translation, the value that you enter in the Name field will be the custom domain name parameter for the endpoint.

  5. Pricing tier. Select a pricing tier that meets your needs:

    • Each subscription has a free tier.
    • The free tier has the same features and functionality as the paid plans and doesn't expire.
    • Only one free tier resource is available per subscription.
    • Document Translation is supported in paid tiers. The Language Studio only supports the S1 or D3 instance tiers. If you just want to try Document Translation, select the Standard S1 instance tier.
  6. If you've created a multi-service resource, the links at the bottom of the Basics tab provides technical documentation regarding the appropriate operation of the service.

  7. Select Review + Create.

  8. Review the service terms, and select Create to deploy your resource.

  9. After your resource has successfully deployed, select Go to resource.

Authentication keys and endpoint URL

All Azure AI services API requests require an endpoint URL and a read-only key for authentication.

  • Authentication keys. Your key is a unique string that is passed on every request to the Translation service. You can pass your key through a query-string parameter or by specifying it in the HTTP request header.

  • Endpoint URL. Use the Global endpoint in your API request unless you need a specific Azure region or custom endpoint. For more information, see Base URLs. The Global endpoint URL is

Get your authentication keys and endpoint

To authenitcate your connection to your Translator resource, you'll need to find its keys and endpoint.

  1. After your new resource deploys, select Go to resource or go to your resource page.
  2. In the left navigation pane, under Resource Management, select Keys and Endpoint.
  3. Copy and paste your keys and endpoint URL in a convenient location, such as Notepad.

Create a Text Translation client

Text Translation supports both global and regional endpoints. Once you have your authentication keys, you need to create an instance of the TextTranslationClient, using an AzureKeyCredential for authentication, to interact with the Text Translation service:

  • To create a TextTranslationClient using a global resource endpoint, you need your resource API key:

      AzureKeyCredential credential = new('<apiKey>');
      TextTranslationClient client = new(credential);
  • To create a TextTranslationClient using a regional resource endpoint, you need your resource API key and the name of the region where your resource is located:

     AzureKeyCredential credential = new('<apiKey>');
     TextTranslationClient client = new(credential, '<region>');

How to delete a resource or resource group


Deleting a resource group also deletes all resources contained in the group.

To delete the resource:

  1. Search and select Resource groups in the Azure portal, and select your resource group.
  2. Select the resources to be deleted by selecting the adjacent check box.
  3. Select Delete from the top menu near the right edge.
  4. Enter delete in the Delete Resources dialog box.
  5. Select Delete.

To delete the resource group:

  1. Go to your Resource Group in the Azure portal.
  2. Select Delete resource group from the top menu bar.
  3. Confirm the deletion request by entering the resource group name and selecting Delete.
