Firebase Function Send User Data to API

Hello - I need a Firebase (node.js) function written for me that will: - run on creation of a new user (authentication) - extract certain user data such as display name, email, photo, uid - send that user data to a HTTPS endpoint (that I will create with PHP) - don't care how the payload comes, GET with URL parameters, POST with JSON or header data, whatever is easiest to send, I can intercept. (FYI Firebase project is all set up on my server I just need the [login to view URL] file)
