How can I pay an invoice using some payment gateway?
In my case payment gateway is Payeezy. I know I can install a module to have a payment acquirer for Payeezy, but this would just add the option for the customer to pay herself using the gateway.
I have saved customer credit card, and I want to pay the invoice using her card via Payeezy API.
If I click "Register Payment" button in invoice I only get method "Cash" and "Bank". Can I add a new payment method?
