Zuora callouts and incoming events

When you connect Stigg to Zuora, Stigg automatically configures Zuora to send certain billing events back to Stigg in real time. This enables Stigg to stay in sync with payment and subscription state changes that originate in Zuora. This page documents every event category Zuora sends to Stigg, the data fields Stigg reads from each callout, and what Stigg does when it receives the event.

​

How incoming events work

Stigg processes events from Zuora in two groups: Automatically configured by Stigg — when you connect the Zuora integration, Stigg creates the following objects in your Zuora tenant for each custom event:

• Event trigger — a condition-based rule that fires when a specific change is detected
• Callout template — defines the HTTP POST Zuora sends to Stigg’s incoming webhook URL, including the payload fields
• Notification definition — links the event trigger to the callout template, activating delivery

Stigg automatically sets up seven custom events: StiggInvoicePaidEvent, StiggInvoicePostedEvent, StiggSubscriptionCancelledEvent, StiggSubscriptionUpdatedEvent, StiggScheduledOrderCompletedEvent, StiggCustomerCanceledEvent, and StiggPaymentFailedEvent. When the integration is removed, Stigg deletes these callouts, notifications, and event triggers from Zuora. Processed by Stigg if received — Customer and Subscription events are standard Zuora change notifications. Stigg’s webhook endpoint handles them when Zuora sends them, but Stigg does not automatically create or manage their callout configuration in Zuora.

Event categories

​

Customer — account payment method updated

Stigg listens for account updates to keep customer payment method information current. When a customer adds or replaces their default payment method in Zuora, Stigg receives the update and reflects it. Data fields Stigg reads What Stigg does Stigg compares the incoming DefaultPaymentMethodId with the one stored on the customer record. If it has changed, Stigg updates the customer’s stored default payment method (type, last 4 digits, expiration month/year) or clears it if the new value is empty.

Subscription — subscription status changed

Stigg listens for subscription status changes so that cancellations initiated in Zuora are reflected in Stigg automatically.

If the Stigg subscription was already cancelled or expired, Stigg moves the billing ID to a historical field and no further action is taken.
