I've been successfully issuing "read" requests to JIRA's REST cloud API (version 2) for the past week.
As of yesterday afternoon, a request like:
https://api.atlassian.com/ex/jira/{ MY_CLOUD_ID }/rest/api/2/search?fields=summary&jql=status=done
results in this error:
Forbidden (403)
Encountered a "403 - Forbidden" error while loading this page
The strange thing is that this only happens for v2 API methods.
My calls to v1 API methods still work as expected with the same token.
I'm using the "OAuth 2.0 authorization code grants (3LO) for apps" based approach to acquire an auth token. The App that I have setup in the app console (https://developer.atlassian.com/apps/) has all grants setup as required:
Any assistance would be greatly appreciated!
