Get users email

[jaksz]

We can get the users profile with chat.getUserProfile(), but how can we get the email?

Here's an article about it. It looks like a real pain. Look in the comments, there's some good stuff.

Also look here https://developers.facebook.com/docs/messenger-platform/webview/permissions
I can't see anything about email here: https://developers.facebook.com/docs/messenger-platform/identity/user-profile

It looks like it's a bit of a black art.

@jaksz I'm quite certain that e-mail is not something you can get directly from the userProfile, and that is by design. Your best option is to ask the user to enter their e-mail directly in some way, though most users will most likely not do that.

Yeah, I don't think it's possible to get the user's email address from Facebook. This might change in the future, but right now your best option is to ask the user directly.
