OAuth Token error in REST Message

[Dominik15]

Hi,

I am trying to integrate Ansible with ServiceNow, however all the time I keep getting this error: oauth access or refresh tokens are not available. verify the oauth configuration and click the 'get oauth token' link below to request a new token. After clicking Get OAuth token I face error : Unauthorized - http 401 error.  I attatched config of my application registry. Can you kindly help me resolve the issue?

Hi, unfortunately a partial screenshot doesn't do much to assist diagnostics and a 401 error code doesn't indicate anything other than authentication failed.
Are you sure that your URL's\endpoints are correct?
Often api/ is followed by the API version and /o/ seems a little unusual?
Are you able to authenticate to the target platform using Postman or similar REST application?

Hi Tony, I have done everything as shown in this tutorial Ansible + ServiceNow Part 3: Making outbound RESTful API calls to Red Hat Ansible Tower up to step 12, where I can't get token. I believe url and endpoints are correct according to the tutorial, same goes for api/o/authorize.

Please check this Ansible document and check you have configured the application for ServiceNow.
