In order to use the API, you have to have Callback APIs. They're not hard to implement, but there's still some headaches if you want to use more than one Callback endpoint.
For example, an application I'm running currently uses a callback URL of http://localhost:8888/callback which is simply going to return the data that was passed in. This callback server is handled by the application itself as a small Flask app that it starts and stops independently in threads.
However, another application (Postman, for example), needs to use its own auth callback point and won't have access to the same callback 'app' that an app in development uses.
Which begs the question: does the StackApps system permit us to specify multiple callback domains for these special cases?
And if not, am I resigned to using multiple registered applications instead, one for each potential callback domain?
