Quick Start Checklist

Use a different Order ID for every test

Before You Test

Requirements

Public IP Address

Not localhost or private IP

PHP 5.4.8+

Or higher version

URL_Notify Setup

Use HTTPS for your notification endpoint

HTTP is not allowed — using it will cancel the transaction

When myPOS calls your endpoint, reply with:

Status: HTTP 200 OK

Body: OK

If you return a different status, an empty body, or an error, the transaction will be cancelled.
