Setup Learning Management System (LMS) with payment gateway

I need install a LMS system which supports South Africa payment gateway called "Payfast". Users who buy a program from me will then receive a username and password and can login to this portal. He can then watch the training videos. There are many LMS plugins but which is best and compatible to work with South Africa payment gateway called “payfast” ([login to view URL]) This how I want this flow. 1. User clicks button on my page to pay for course on my sales page. It will ask him for his name, surname details and then he will pay using “payfast” South African gateway to make payment. 2. Once he pays, he must receive email with login details. He will then be able to login to the LMS system to watch the online courses which he just paid for. Please check which LMS system can support payment gateway "payfast"
