The IPN system
Here you will find the specific variables our payment checkout system forwards via IPN immediately upon a transaction is processed. Note that the IPN system is for advanced users only and it requires programming skills on your end.
Some general notes to consider:
1. Please configure your IPN pointing to a .php file (recommended to be hosted on a secure https:// domain) from where you can grab all the IPN variables we send from POST.
2. Any variable with an empty value will be posted as “N/A”.
