Hi @pieter. Thanks for this awesome plugin. When PayFast sends a notification to your notify_url (for example https://mysite.co.za/api/1.1/wf/itn_notification) how do I read the parameters and pull them into my database? For example, when the customer orders an order is created with a unique order number in the database and the status set as pending (per the demo app). How do I update this status now from the notify_url to say complete?
