PHP paypal billing agreement

Question

This is very general question.
I want my user to sign a Paypal billing agreement with me and bill his PayPal account in the end of the month by usage.
All the code examples I had encountered are using predefined packages, while I need to bill the user by the usage which changed from month to month.

Does anyone knows a PHP code example for this? Or do you have any link with good How To / code example?

Thanks!

Answer 1

For variable amounts you'll need to use Reference Transactions or Preapproved Payments .

Since you're using PHP I'd recommend taking a look at my class library for PayPal . It will make this very simple for you, and comes with samples as well as empty templates you just have to fill in.
