Cart and Paypal integration

i once did integrate PayPal into a php framework using paypay restAPI ; that was a few years ago .

I remember it well since i got James Turing a living descendant of Alan Turing to test it by buying something.

The display of items , with hidden ID and then coding so items were removed after someone bought something was bad enough. But the nail in the coffin for me was a shift in the level of support from Paypal.

There was an obvious bug in paypay code; to communicate with Paypal was a nightmare and then they updated
things without any decent documentation. Basically the quality of developers working on the code and help from them went downhill dramatically.

I don't know if that has changed but i for one wouldn't rush back to PayPal
