Getting Http Status 0 when triggering REST Message to Get OAuth Access Token

[Mrman]

Hi ,

I create a Rest Message in ServiceNow to call a 3rd party endpoint to request access token .

I have included the client id, client secret , grant type as client credentials , and audience in the Body and tested in Postman . I am able to get the response and getting access token.

But the same configuration when I do in service now using REST message , I am getitng Http Status as 0 and Error code as 1. 

Error message as :Request not sent to uri=

Please suggest .

Hi, without any details of your configuration the forum can only guess at your issue.
Perhaps you can update this thread with clear and specific information?

Hi,

Share the configuration screenshots etc

If you are able to test via Postman then it should work fine in ServiceNow Rest Message as welll.

@Ankur Bawiskar I am now getting the below error when testing the Get Token Rest Message in Service Now.

The same client id , client secret and other parameters I am usng in Postman and I am getting the token.

Please let me know what additional parameters I need to add in ServiceNow rest message.

Http Status : 401
 Error message : Method failed: (/oauth/token) with code: 401 - Invalid username/password combo

Response : {"error":"access_denied","error_description":"Unauthorized"}

Rest Message Configuration :

====================

Iin POstman I am able to get the Token successfully when I am passing these parameters in the Body .

Please suggest.
