Hey everyone,
I don't know why, but I can't seem to get how you pay for invoices that are issued after the initial purchase?
I've got my own payment gateway module, which works just fine with the first purchase, but after clients start getting reminders to pay their bills, how do they pay them exactly, as the link in the email message points them to the invoice, but it has no "Pay" button and the "Pay To" part (the part on the right side) is empty.
Any quick tips or ideas would be very much appreciated.
Let me explain how my gateway works: the client is redirected to the payment gateways website, which allows for online bank transactions, creditcards and even wire transfer. It then comes back to WHMCS and does some authentication and if all's good, marks the invoice paid and activates the account.
Now, how can I use that in new/upcoming invoices, since some of my clients will be paying monthly and some yearly?
There has to be a way to do the same kind of redirection as with the initial purchase, right?!
