I am trying to use Azure Text Translation Service, but it give me 401 unauthorized when I try to use barerr token

I am trying to use Azure AI Text Translation. With the Ocp-Apim-Subscription-Key method, it's working fine.

However, when I try to use the barrier token, it gives me 401 unauthorized. I have already added my web App as managed Identity in Translator service to give permission to my web app on translation service..

my document translation is working fine, my web app can access and translate documents. But my text translation is not working.

My question is, does the text translation service have limited authentication types?

End point: https://api.cognitive.microsofttranslator.com/translate?api-version=3.0&to=de

I also tried postman also, to send a barrier token, but it's not working.

my C# code that is deployed in web app is using below method:

var credentials = new DefaultAzureCredential();

var tokenResult = await credentials.GetTokenAsync(new TokenRequestContext(new[] { _translationConfigOptions.TranslatorEndpoint }), CancellationToken.None);

And token is sent to Azure translation service. that throws 401.

Thanks for the question, All Azure AI Translator 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 api.cognitive.microsofttranslator.com.

Here is the document for the same.

Yes, with Ocp-Apim-Subscription-Key method and End point, the text translation is working fine... My Concern is that i don't want to use the subscription key method.
What other authentication options does it support?
