Power Platform Community Forum Thread Details

I am trying to authenticate to Azure and generate a Bearer token in PAD. For which, I have passed all the necessary details in the "Invoke web service" action, like URL, Content type, Request body etc. But I am getting the error:

"error":"invalid_request","error_description":"****: The request body must contain the following parameter: 'grant_type'.

But I have already provided the grant_type in the request body (as you can see in the screenshot below). The same request is working fine in Postman. What am I missing?
