Can payment gateways other than PayFast be used on Shopify?

Internationally, Shopify can integrate with many popular payment gateways such as PayPal, Google Checkout, 2Checkout, etc.

In South Africa however, we don't have access to those same payment gateways.

PayFast and PayGate are the two credit card and InstantEFT gateways that will integrate with your South African online store and you can also use SnapScan and Zapper as 'Alternative Payment Methods'.
