we have a website and it generates username and password for users.
We're thinking to use Paypal for payment portal. But we need it in a way so that when payment is interrupted, access to website gets denied.
(for example, if credit card expired or maxes out or when credit card gets canceled).
For this, Paypal requires customization (I think) with some sort of a Perl script.
Is this correct? I have the paypal documentation and there's something on page 148 mentioning this.
