I am trying to make use of the "notify_url" setting so that I can handle the backend return to my "notify" page. Can someone please explain to me where I should place such a file and how do I get it to be send to the payfast payment site? The examples on the Payfast development page show it should be inside a <form> and I cannot see how it is done.
I tried added it inside a block in the "Checkout Pages" layout but it does not work.
I get the following error:
The supplied variables are not according to specification:
cancel_url : cancel_url must be a valid URL
notify_url : notify_url must be a valid URL
return_url : return_url must be a valid URL
