API Periodic Bills

API PERIODIC BILLS



Below are examples for periodic bills (recurring transactions).
Please make sure you do not set threshold to be more than 5.
Threshold is the amount of times it fails before you are sent an email notification.
You can set "installments" to -1 so that the periodic bill continues billing for an infinite amount of times.

Below are XML examples for different transaction types.

Why don't my transaction show up in the reports when I set RESULT to GOOD?

When ever you set RESULT to GOOD, the transactions will not show up on the LinkPoint Central reports. You will need to change it to LIVE for the transactions to show up in the reports.

Why do I keep getting an invalid XML error for a periodic bill?
