I'm working on a custom payment plugin which is trying to accommodate non-instant IPN response. Unlike PayPal, where customer pays directly, my third party service (one that handles mark received payments as paid) might takes some time before they can confirm if a payment has been made for an invoice. So, I'm trying to find a way, to trigger the Tansaction_Incoming method when my third party service post the IPN request to my server. I have this in mind; Create a PHP file to handle the IPN post, and parse the request. In that file, I need to setup everything so it can work with my aMember. (I don't know what are *everything*) Then, trigger the plugin incoming transaction method from that file. Can somebody lead me to the accomplish this? Thanks in advance.
