Hi John, thank you for this really great guide. I've done all the steps, trying to call an end-point from APEX on my OCI ADB and I get ORA-01031: insufficient privileges. In my case my principal is APEX\_240100. The end-pont works fine from the browser or Postman, has no authentication required and it's an HTTPS address.

Any idea that can help me figure it out? Thanks a lot in advance.

Hi, with ADB you should not need to setup ACLs. The error indicates that it is an ACL issue though. It could be that Oracle is blocking that particular URL for some reason.
