I'm following https://developer.paypal.com/docs/checkout/integrate/ to integrate a Payment Button using Checkout
All works very nicely until I get to STEP 6 Verify the Transaction.
Client side is OK - I can see it uses fetch to invoke the paypal-transaction-complete end-point - seems logical
But then the next bit of code (2. Server) neither the Javascript nor the PHP - are these supposed to be implementing the end-point mentioned in the client side?
I'm very confused...
