How can users purchase credits for my app? (e.g. via PayPal)
I am starting a website that will provide various services that our clients will (hopefully) pay for.
I thought it would be best if my clients could for instance buy 100 "credits" for $100 via PayPal. Somehow PayPal would let me know which user made the purchase and I would store those 100 credits in my database. This user could then purchase 100 credits (i.e. $100) worth of my services.
Could you tell me the best way to achieve that? Does PayPal offer something like that?
One more thing: Is it even possible to make everything this "automated". Can PayPal run one of my scripts with specific parameters (user ID, amount, ...) after the purchase has been done, so I can handle this user's request automatically (or add credits to his account).
Thank you very much for your answers!
