This documentation is for the Payfast Gateway found on the WooCommerce.com marketplace.
Sandbox Mode Only
This gateway does not support refunds via the REST API and therefore Robot Ninja does not ever take any real payment and can only be tested in sandbox mode.
Make sure you have the latest version of the Robot Ninja Helper plugin so that Robot Ninja knows when this gateway is in sandbox mode.
The Payfast gateway has Subscriptions support and so Robot Ninja also supports testing the checkout with Subscription products.
To specify a subscription product, you can set the Subscription Product ID within the store settings found in RobotNinja.com > Settings.
