Confluence API OAuth error: Current user not permitted to use Confluence

I’m not sure what I’m doing wrong: I have successfully authenticated with my Confluence through the 3LO app auth flow, but when I try to run any API commands, like, I get a “Current user not permitted to use Confluence” error. If my admin goes to look at the authorizations for my user for this app, it’s definitely authorized…anyone have any ideas what I’m doing wrong?

I’m getting the same error, but only on some instances. Have you found any solution for the issue?

If you authenticate using the Atlassian Oauth2 (3LO) you can access the Confluence REST API by using this URL format as your base URL.{cloud_id}/rest/api/

To get the cloud_id you should send a request to this endpoint.
Here you should provide the token you generated by the oauth flow.
