How to get a link from an authorized facebook and twitter account?

Question

Facebook

Hello.
I want to give the opportunity to specify my account on facebook and twitter, but since not everyone knows which link to copy (and how something is copied in general), I would like it to happen in one click of a button.
Something like:
1) Clicked
2) Logged in
3) Link inserted
Is this possible?

Answer 1

It is quite possible, see the documentation for the relevant APIs
