Payment Gateway For South African Companies

Hi folks,

I desperately need to setup a local (South African) payment gateway. 

PayFast is THE MOST popular payment processor in South Africa.  Here are the details:

PayFast - http://payfast.co.za/

Their documentation - https://www.payfast.co.za/documentation

Our local currency is ZAR (South African Rand)

Please advise the process involved to set this up.

Thanks,

Peter
