Both URL's will work for making REST API calls to our Sandbox environment.
Hi Lee,
I definitely do have the permission, here is a screenshot: https://prnt.sc/oj5jgm. But quick question, when you say I 'need to perform a sync before the changes take effect', what do you mean? I've re-authed to make sure that the permissions are up to date.
If you change the permission after the app is installed to a merchant you must uninstall, re-install the app to get the new permission.
