Microsoft Translator API Error Message: The received token is of incorrect token type

Question

I am getting 400 error message as shown in image below, when I try out the Translation API using Try it out link http://docs.microsofttranslator.com/text-translate.html

I am using the Access Key generated from Azure Portal for Cognitive Services Free trial.

MS Azure Portal Link

I have read on MS support blogs and I tried all the suggestions mentioned in them. But everytime, I get the 400 Status error as shown below. Can someone please help me to resolve this issue??

Answer 1

You need to get an access token first (docs here) by doing a POST request:

curl --header 'Ocp-Apim-Subscription-Key: <YOUR-API-KEY>' --data "" 'https://api.cognitive.microsoft.com/sts/v1.0/issueToken'

And then use that token in the Authorization header. (appId has been deprecated).

curl -X GET --header 'Accept: application/xml' --header 'Authorization: Bearer <YOUR-TOKEN>' 'https://api.microsofttranslator.com/v2/http.svc/Translate?&text=this%20is%20my%20name&from=en&to=af'

Answer 2

You can use Microsoft Translator API in 2 ways (see the docs):

• in 1 step: invoke (GET) https://api.microsofttranslator.com/V2/Http.svc/Translate?text=Neoliberismo&from=it&to=en, passing Ocp-Apim-Subscription-Key: your_subscription_key as request header
• in 2 steps, with OAuth:
  • invoke (POST) https://api.cognitive.microsoft.com/sts/v1.0/issueToken, passing Subscription-Key=your_subscription_key as query parameter or better passing Ocp-Apim-Subscription-Key: your_subscription_key as request header
  • you'll get a token that expires after 10 minutes
  • invoke (GET) https://api.microsofttranslator.com/V2/Http.svc/Translate?text=Neoliberismo&from=it&to=en, passing Authorization: Bearer the_token as request header
