Hello, I am curently having problem with server to server Oauth app that i have created. App should be usable for useres that have been connected to main ac. Ap works when i am using main ac, but when i want to install app to different admin acc i get error as an (Redirect URL is required. (4,700)). Also i was contacting the support thay asked me if i did put redirection url and i dont have option to put the url when building the app.
Here is the app link : App Marketplace
