In order to buy points, we need to pay, and to do that, we need a “Payment Gateway”. Gateways are bridges that connect the buyCRED add-on with popular online payment operators, such as PayPal or Payza.
The add-on comes with built-in support for five online payment operators and a manual gateway for bank transfers. Once the add-on has been enabled, all gateways you have installed will become available on the “Payment Gateways” page in the myCRED menu.
If the built-in gateways are not to your liking, the myCRED store has an ever growing number of gateways that you could use instead. You can also find a growing list of free plugins here.
