How to recover the user phone after login ?

Good question, we are at least 2 others in the same situation. Problem hasn't been answered yet.

What I did is an httpbin get request to retrieve the email set in the login page and put it again in the postlogin page

no problem for the email, it works very well but for the phone ?

Well..
These are the variables supported by bravo
https://docs.bravostudio.app/connnec-api/request-url-variables#built-in-variables

What if you create yours, name it user.phone and then do a get request :
https://httpbin.org/get?name=${user.phone}

Yes, the phone variable is not yet in the supported variables. I tried the https://httpbin.org/get?name=${user.phone} and https://httpbin.org/get?name=${user.number} queries but it doesn't work!

I've been able to solve the post-login issue for Phone now. But I still don't know how to setup an API for conditional display of the post-login page. 

I also asked the Bravo Team about the variable for phone number like how we have for email but they said that there's no variable for that at the moment.

Can you explain then ?

Maybe attend this Q&A today.

It will be about variables ! Si tu trouves une solution n'hésite pas à commenter le post et le mettre en [SOLVED]

Yes, I'll look into it! Thanks for your feedback 👍

I would like to know too. Stuck in there for few weeks.

, I apologize, I got caught up in some work.

So for post-login to work for Firebase phone login you'll need to have a screen in which you show users options for login methods, even if you have only one login method that you're going for (you can list just that one). On this screen you need to put both the [post-login:action] tag and the [page:login] tag, even if the actual login is on another screen.

Then you can setup post-login based on the success or error status codes, but that's where I'm struggling. My Airtable request is sending status code 200 - OK even if the user.id doesn't exist in the table.

As of now to test the post-login screen I've set it to show both in case of success or error and it works fine.

I've been told by the Bravo team that for Airtable it's better to use a tool like Make or Zapier for custom status codes to pull this off but I haven't been able to make that work yet because of the dynamic element which is the $user.id variable. If you guys can figure that out, please let me know. 

Hope this helped and thanks in advance!
