By setting up Xero according to the steps outlined here, the integration will handle the bank feeds automatically from our side and update your Xero systems when there are successful payments received, that were actioned from Xero. Additionally, it will notify Xero when a payout from PayFast is made.
In essence, the 'Get bank feeds' button is not operational for PayFast as a button for the user to press, but rather, PayFast will automatically handle the bank feeds.
