Steps to Implement Pay it @POST




 

Technical Tasks


Overview

The structure of the Pay it @POST web site provides considerable flexibility.

We accept a range of parameters when you direct the customer browser to our web site. These control how we handle the payment referral. Default values can be registered for most of these parameters.

We allow you to nominate up to three return points to handle the cases where the customer completed a payment slip, the customer cancelled, or our server believes the parameters you passed are in error. These return points can be pre-registered, or supplied with an individual payment referral.

Optionally, you can request our server to directly advise your server when the customer has either accepted or rejected our invitation to Pay it @POST. This helps to guard against situations where a customer becomes confused and cancels their session without returning to your web site.

You can determine the current status of your payments at any time by requesting an XML document from our server. The enquiry can target an individual payment or all payments that have changed status in a nominated date range.

This section provides complete technical details of the interface between a merchant's e-Commerce system and Australia Post's Pay it @POST service. There are four main interfaces to consider:

1.

How to refer your customer to Australia Post so we can collect payment on your behalf.

2.

How to confirm your customer has completed the order slip.

3.

How to determine when Australia Post has collected the payment from your customer.

4.

How to get a detailed settlement report listing the payments collected on your behalf and the fees charged by Australia Post.

All four interfaces are implemented as links to the Pay it @POST web site.
