Configure the notification
Disable the out-of-the-box payment retry in your Zuora tenant before you run Configurable Payment Retry (CPR) to avoid disruption to the retry service.
You have configured a callout template for CPR with the Payment Run Completion event. For more information, see Configure the callout template for CPR.
Zuora creates the notification. When Active is switched on, CPR receives a callout each time a payment run completes and starts retrying failed payments.
