After a while I got the time to publish this first (and incomplete, sorry) library for Paypal v2 which is including at this moment orders and payments.
It’s now battle tested and I can ensure it’s working perfectly for the funcionts that are implemented however, I’ll be adding more parts of the API and publishing new improvements and fixes (if any). Don’t hesitate to use it or even help with documentation, testing, or adding what you need for it.
