Handling a callback from an API

[TwoWheelDev]

I'm in the process of developing a module, that will need to handle callbacks from the third-party API.

The pages for the callback will need to be accessible from frontend without a login, what's the best way to handle this from a module. Is it possible to do without manually creating the pages... I guess some sort of registering a URL that processwire will send to the module to do the processing
