Ask HN: Keeping endpoints version in sync with a mobile app

Hey HN!

I have a question.

I have a mobile app in react native that depends on a backend that I made.

The thing is that sometimes I want to change what data a backend endpoints receives. But I don't know how many users have updated their app to the latest version.

This seems like an extremely hard problem.

Should I start versioning my endpoints with /v1 ... /v2, etc? And then keeping track of when they stop being used in order to delete the old ones?
