But I'm not beign able to get the access token to interact with the Twitter API on user's behalf. I already checked all the provider properties and the mAuth object but I can't seem to find the token. How can I retrieve that after the successful login? The docsdoesn'tseem to sayanything about that token

You’re welcome, these questions should probably be for stack overflow and Google… However, as my last bit of advice, check out the twitter documentation (you don’t need to add the dependency because firebase ui already has it, but you probably should to ensure you always get the latest version). The rest is pretty clear to compose a tweet. Hope this helps!

BTW, you don’t need your users to log into twitter for what you’re trying to do. The consumer key and secret are found here: https://apps.twitter.com/ which is all you really need. Firebase-UI is meant to let users authenticate with Firebase services such as the database and storage. It also gives you a unique uid to let you identify your users.

@SUPERCILEX thanks for chiming in, @juanlet I am going to close this issue as what’s left has more to do with the Twitter API than FirebaseUI. Hope you get it all working.
