Why this integration matters

Many South African businesses already have a preferred payment gateway. With Illumi, you keep using what you know — and simply add a pay link to invoices.

Payments are handled by your connected provider.

How it works

  1. 1
    Connect PayFast in Settings > PayGate.
  2. 2
    Send invoices by email (or share a link).
  3. 3
    Clients pay online and invoice status updates automatically (provider dependent).

Credentials you’ll need

You can find these in your provider dashboard. In Illumi, go to Settings → PayGate, select PayFast, and paste the keys into Test or Live mode.
