Is it possible to post promotional activities to the social media accounts of users who have logged in via Firebase Social media authentication?

Question

I have implemented the social media sign up/Log in via firebase authentication . I get the User UID from the Firebase-SDK when a user is authenticated . Can this ID be used for targeted ad campaign to those particular users ? If it's not feasible then how I can achieve that ?

Answer 1

Firebase Authentication asks for the minimal set of scopes that it needs to sign the user in (read-access to name, email, profile picture URL). This does not allow your code to make any posts on the user's behalf.

On adding more scopes, see:
