In any case, if you revoke the token, the information will not be valid anymore, so no need to delete the attachment.

If I revoke the token, will it effect on the other connected system via this account because CRM has connected with other system via this client id?

Could you please help me delete this attachment only?

I got refresh token with C# code with your help.
But, when I try to invoke CRM OAuth Token API, it returns 400 the below status code.

ResponseStatusCode='400' - ResponseContent: {"error":"invalid_request","error_description":"AADSTS900144: The request body must contain the following parameter: 'grant_type'.\r\nTrace ID: d4c1910d-b0b4-4ec6-93f3-c190887d0201\r\nCorrelation ID: da5a9348-f3e1-416e-90b5-9b10b1e6789b\r\nTimestamp: 2022-03-23 10:55:19Z","error_codes":[900144],"timestamp":"2022-03-23 10:55:19Z","trace_id":"d4c1910d-b0b4-4ec6-93f3-c190887d0201","correlation_id":"da5a9348-f3e1-416e-90b5-9b10b1e6789b","error_uri":"https://login.microsoftonline.com/error?code=900144"}


This is my content to invoice API. grant_type has included.

 

[edossantos]

The Content Type should be set to application/x-www-form-urlencoded, it's not JSON.

Maybe that confuses their server...

Now in this request you should be sending JSON, but you're sending URL encoded form data.... Check the API specification to understand the payload you need to include in your request.

Yes, the Content Type is fine, but the Content is not JSON.

@edossantos

So, what should I do to be Content Type is JSON at CFD?
I see only that entry point at Web Service Rest Component of CFD
