Can I pull in someone's Facebook profile pic

Hi I’m new to and loving it so far.

Can I pull in their FB profile pic based on their email or phone match?

These are not users who sign up…it’s a crm so it’s users that I enter.

Yes you should be able too. But getting access to Facebook after the whole Russian interference scandal is another story. I had many customer that failed to get through the door

Yes,you can do this easily. Need a Facebook Developer account and certainly based on that users privacy settings
