Api Bearer access token from OAuth

[trondwn]

I have an issue when retrieving access token with client_credentials subsequent calls using token fails with error 500, but access token from refresh_token works as expected.

seems like token is valid because it timeout and concur reports it.

Any ideas on what the problem might be?

@trondwn Thank you for the post. I am sorry for your experience. Is this when you are logging into SAP Concur on the web or mobile app? Do you have a screenshot of the error, if you see one that you can share?

I look forward to hearing from you.

hi @leedau ,

this is connecting from SAP PO with REST adapter( same with Postman) to use Concur API.

And using OAuth2 flow with grant_type client_credentials .

{
"Error": {
"Message": "Internal Server Error",
"Server-Time": "2023-09-08T03:24:44",
"Id": "7D79C1D5-9A67-45BC-A385-6923E20D794D"
}
}

using refresh_token return the expected respons.

@trondwn Thanks for the additional information. It appears that an Authorized Support Contact has opened a Support Request with the SAP Concur Support team for assistance. The case has been assigned and updated. See below. For additional questions, please continue to work with your Authorized Support Contact at your company, as there is an assigned Web Service expert assigned to the support request. 

Our APIs will only work with Password grant type or Refresh Token grant type. The Client Credentials grant type is for Event Subscription Service (ESS) v4. The access token will not work for our APIs if password/refresh_token grant type is missing.
