Skip to main content
This endpoint fires a synthetic webhook event to your subscription’s destination immediately, without waiting for any on-chain activity. The event flows through the same delivery pipeline as a real event — Standard Webhooks signing, retry logic, and all delivery headers — so you can verify your full handler stack end to end. With no request body, the endpoint sends a service.ping event. With a body, you can specify the event kind and provide your own data payload to simulate a real event shape.
