Thanks for your support in advance. I would like to get a hint where to enter the code for a "payment-resource“ in Wordpress. I´m using "pure" Wordpress installation without any plugin or shop system. What I understand is, that I need to transfer the payment parameters to Paypal via a REST API transfer. My question is: where and how do I enter the code (like example code https://developer.paypal.com/docs/paypal-plus/germany/integrate/create-payment-resource/) on the wordpress page or the "buy" button? This would be the first step of paypal interaction. Would be great if there is any documentation describing this in more details with Wordpress. I set up a test site at https://ame-test.de/checkout-service-a/ for testing purposes.
Thanks for your support!
