When a user verifies their email address, I want to receive some notification on my client app (iOS/Android).
I need this to ensure that I can unlock additional capabilities for those users whose address is verified. How can I achieve this?
Currently, the only way to do this is to call the reload method on the User object. However, it is not an ideal way of dealing with this situation – after all, I have no idea when they would click on the link. So, performing a reload every time my app becomes active seems excessive.
Maybe there is a trigger which I missed?
回答1:
Well, what I do is, each app launch I query the user object for its verification status; if it's not verified I send a verif request right there, if not sent before, and if it is and it's the first time, I show some thank you text and move on. I don't think there's an actual notification you can hook with for when the user clicks the link in the email, but alternatively you could build an admin node function server side to check every now and then for verifications and send pushes to the relevant devices.
