Transaction Notification

This code steps you through the basics of configuring Web Hooks to handle data that gets posted to a URL that's associated with your BluePay Platform Account. When you're using this code in "test mode," only test transactions are returned.

Please contact our integration team with your gateway account ID & the URL of your receiving script to have this feature enabled.

The following sample code calls a routine from our Code Library.
