How this service works
Event relay. Register a webhook, trigger events.
Output
A confirmation response indicating the event was received and relayed to registered webhook listeners, typically including delivery status or acknowledgment details.
Example use cases
E-commerce order status notification
“Fire a webhook event called 'order.shipped' with a payload that includes the orderId 'ORD-9912' and the tracking number 'UPS123456' so our fulfillment listeners get notified.”
CI/CD pipeline event dispatch
“Trigger a 'build.success' event on the webhook relay with payload data showing the repo as 'my-app' and the commit hash 'a3f9b2c' so the deployment automation kicks off.”
IoT device state change relay
“Send a webhook relay event named 'sensor.threshold_exceeded' with a payload containing the device ID 'sensor-42' and the temperature reading '98.6' to alert the monitoring pipeline.”
Technical details
Endpoint
POSThttps://webhook-api-production-4378.up.railway.app/trigger?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-use webhook relay to dispatch named events to pre-registered listeners without managing your own webhook infrastructure. Ideal for automation pipelines, event-driven integrations, and IoT or CI/CD notification workflows where you want to fire-and-forward events on demand.
Side effects
- Missing required 'event' field returns a 400 validation error
- Unregistered or inactive webhook destination may cause silent delivery failure
- Malformed payload object may cause a 422 or parsing error
- Network timeout on downstream relay delivery may result in partial delivery
- Payment failure (x402) prevents the trigger from executing
