Ok great. Yes I will sort the parameters. Thanks a ton! Going to go ahead and implement that into the CakePHP Plugin/Component this week.
I felt the need to create a new one, because the one on GitHub is a bit outdated and is not functioning correctly. In addition the Plugin I have created allows Developers to quickly get going with the ability to store Shop Owners in a database and manage "uninstall webhooks" via the Plugin, instead of having to implement it all into their APP.
Why are some APP passing the "code" parameter when linking out from /admin/apps? Just curious.
Thanks for your help.
