Could someone provide an explanation (with an example) for the recurring payments URL field found on the Add Payment Processor form when using Vanco Payment Processor? It is my understanding it is used for processing the Instant Payment Notification (IPN), a message service that notifies you of events related to your payment transactions.
Mike, as pkeogan stated, the field does not need to be populated for Vanco.
I believe that some payment processors have different URL's to submit recurring payments to, thus the need for this field. In Vanco's case, all transactions should be submitted to the one, single URL.
If the Recurring URL is not specified, CiviCRM defaults to the API url.
