Webhooks for Google/Facebook

Hi all,

I'm interested in the idea of setting up webhooks for lead campaigns on Google and Facebook, getting prospective customers to sign up to our e-news. In the past we've only set up a lead campaign on Facebook where we'd export a CSV and import the data back into Tessitura manually.

Has anyone attempted to set up a webhook for this function before, and if so: any hints on setup and how to map these fields?
We'd probably only capture first name, last name, and email address. 

Thanks!
