I'm really struggling to understand the options available on PayPal. In short, I want to be able to register the payment with PayPal (from the server - so the variables are never visible on the client) and then redirect the customer to the PayPal website to complete that purchase... with a webhook/IPN in the background to confirm a successful payment. Obviously there is the "cmd=upload" option, but it seems a bit simple and prone to meddling because the variables have to be written out to a self-posting form on the client... yuk! I've been looking at the RESTful API, but the documentation is hard to follow for a new-comer. It seems that you have to capture card details on the website itself and pass them. Is that correct? Is there not a way to register the payment details from the server, get a unique link and then simply redirect the customer to that link?
