I have created an embedded app. Now I want to integrate Billing API. My question is what will be the flow.
First user will land on the permission page, after selecting the app from App store.
Will I charge the user right after that authentication, or will I create a screen with a button showing user that now you will be charged. will the confirmation_url and return_url will work same as they are work for non-embedded apps?
It works the same. We put payment as part of the signature checking process or otherwise it can be bypassed if it is only in your install flow.
Yeah this is kinda of a hairy one
