I'm writing an app in React Native that uses Amplify User Pools for the user to sign in/up with the withAuthenticator method. My intention is to use a unique user id to create a User object in my backend so I can create a new user or get the details of the user who just signed in. My understanding is that a unique userId I could use would be the Identity Pool Identifier.
My flow would be:
- Show signIn/signUp screen
- Once the user signs in I grab his unique identifier (Identity Pools Identifier?)
- Get the user details for a user with that id from the backend
- If no user with that id exists, create a new one with it.
It would seem quite standard, but I guess it's not because I can't find anywhere any clear detail of such an implementation. I would expect withIdentifier to have a sort of callback with the signed in user details, but I can't find anything of the sort.Am I missing something here?
