Https://id.atlassian.com/error - how to troubleshoot?

Hi All,
https://developer.atlassian.com/cloud/jira/service-desk/oauth-2-authorization-code-grants-3lo-for-apps/

I would like to do some troubleshooting with id atlassian com/error

I believe I created valid OAuth credentials.

Based on the error_description the Callback URL is the problem.

connection=&lang=&error=unauthorized_client&error_description=Callback%20URL%20mismatch.%20https%3A%2F%2Fnourl.example.com%20is%20not%20in%20the%20list%20of%20allowed%20callback%20URLs&tracking=5a5de670233324cc5b05

Do we have a list of known, valid callback URLs, would localhost work?
Or a list of known disallowed domains.

Hi @matjung,

would localhost work?

Yes - localhost will work.

Does the value that you’re providing in the redirect_uri query parameter match the value you entered in the field labelled Callback URL in your app at https://developer.atlassian.com/apps?
