Service Account OAuth2 - API always returns 401?

[Iker Gómez Eiras]

I'm trying to set up a service account to automatically create tickets in our ITSM service when servers trigger specific alerts in their monitoring.

But when I try to call the endpoint to create the issue, through this endpoint:
https://api.atlassian.com/ex/jira/<instanceid>/rest/api/3/servicedeskapi/request

I always get a "401 Unauthorized; scope does not match" error.

I've tried and created multiple OAuth2.0 tokens with different scopes, using only classic, only granular, and both. Always making sure they have the scopes specified in the documentation for that endpoint.

I've also made sure that the service account has Service Management license and I've also added it to a group that is part of the "Service Desk Team" role in our support projects.

But always the same 401 error.

Am I being a complete idiot and missing something, or are API calls to the servidedesk enpoints just broken for OAuth tokens?

Hi @Iker Gómez Eiras 

Is the instance ID correct, use: 

https://<my-site-name>.atlassian.net/_edge/tenant_info

Is the Service Account also a customer, as using the current API endpoint does require this.

Yup, that was it, thank you very much!
