userID for authentication

[Anish]

Is the UserID we recieve, the PSID?

If so does the PSID ever change? And can I use it for basic authentication to see if a user belongs to a segmented group of users or if the user is on a specific google sheet?

Thanks

Khashayar,
You mentioned account linking in the topic below. Could you provide some more details on how you ended up implementing it. Will it work on a page only bot or does it have to be page & app with it own permissions?

External authentication page

Good morning everyone, I would like to know if it is possible to open an external page so I can authenticate my user with a login and a password, if at all possible, how do I synchronize this page with Flow XO to get the authentication return ?. I recently opened a question about this by email, however I was informed that it is possible to do this, but I do not know how to do it. can you help me? Thank you

With gratitude.

It is indeed the page scoped user ID. We receive this direct from FB so you can be sure that when someone returns with the same PSID, that is the same person.

Actually that’s really how setting an attribute against the response path works.

Does that help?

Helps a hellalot! thanks. I just need to set up some basic user authentication.

In Python/Django I used to link a system user with a Messenger PSID and then I can keep a track of users on my side. Until I know, the Messenger PSID does not change even if user remove the conversation and come back.

Thanks, clears up some processes for me.

I think you may get a new PSID only if you delete a convo on web version of Facebook Messenger. If you delete on mobile I believe you get the same one back if you talk to the bot again.

Hey, sorry for not being around for a few days!

I never got account linking to work. I think since it needs a callback, flowxo doesn’t support it yet
