Scenario
Shopify sends an order webhook, Webhook Guard forwards it, and the destination returns 200. The ERP order is still missing.
Operational problem
Teams often treat the 200 as proof that the order synced. It only proves that the component returning the response accepted the HTTP request.
Incorrect implementation
- Return 200 before recording or queueing the event.
- Mark the order synced when the endpoint receives the request.
- Use delivery success as the only alerting signal.
Safer implementation
- Persist or enqueue the event before acknowledgment.
- Track received, delivered, processing, committed, failed, and reconciled states separately.
- Alert when delivery succeeds but business completion does not appear.
Evidence and observability
- Delivery attempt status and response time.
- Queue message ID and worker trace.
- Database commit record and downstream system identifier.
Stage-by-stage timeline
| Stage | Status to record | Evidence owner | Failure signal |
|---|---|---|---|
| Provider delivery | Shopify attempted delivery and received a response | Shopify delivery logs | No attempt, non-2xx, redirect, timeout, or signature failure |
| Intake status | Webhook Guard received and authenticated the event | Webhook Guard Event Detail | Missing event, invalid signature, or rejected intake |
| Downstream delivery | Webhook Guard delivered to the configured destination | Delivery Attempts | 401, 403, 429, 5xx, timeout, or retry exhaustion |
| Application processing | The destination persisted, queued, and processed the work | Application logs and database | No queue message, worker failure, rollback, or validation error |
| Final business state | ERP, OMS, WMS, or database reflects the operation | Downstream system | Missing or partial external record |
What each status proves
A status is trustworthy only for the boundary that emitted it. The safest incident model keeps provider delivery, intake, downstream delivery, application processing, and final business-state status separate.
| Observed status | Proves | Does not prove |
|---|---|---|
| Shopify received 2xx | The provider request reached an endpoint that returned success | Webhook Guard routed it or the ERP processed it |
| Webhook Guard event exists | Webhook Guard received and recorded the event | Any configured destination accepted it |
| Destination returned 2xx | The destination HTTP boundary accepted the request | A worker committed database or ERP state |
| Worker completed | Application processing reached a known terminal state | External ERP state is correct unless verified |
| ERP record exists | The business state was created or updated | The local sync status or mapping is correct |
Example: delivery succeeded but ERP processing failed
- Shopify delivered an order webhook and received HTTP 200.
- Webhook Guard recorded the event, matched the ERP integration, and received HTTP 200 from the destination.
- The destination returned before enqueueing the ERP job.
- No queue message, worker trace, or ERP order exists.
- The correct diagnosis is application processing failure after downstream delivery, not provider delivery failure.
Recommended status model
- Provider delivery status: delivery ID, response code, response time, and retry count.
- Intake status: authenticated, invalid, recorded, and matched.
- Downstream delivery status: destination, attempt number, response code, response time, and retry state.
- Application processing status: persisted, queued, processing, committed, failed, and reconciled.
- Final business-state status: ERP, OMS, WMS, inventory, fulfillment, and local mapping verified.
Monitoring and correlation requirements
- Propagate Shopify delivery identifiers, Webhook Guard event IDs, queue IDs, worker trace IDs, and downstream request IDs.
- Alert when delivery succeeds but final business state does not appear within the expected operational window.
- Store enough evidence to distinguish retryable endpoint delivery from non-retryable business validation failure.
Pipeline context
Text equivalent: diagnose the event from source action, subscription, provider delivery, intake, routing, downstream delivery, customer processing, and final business state.
Product visibility
Webhook Guard visibility boundary
- Webhook Guard records downstream delivery attempts, response status, response time, and attempt number.
Need the event history before you can diagnose the failure? Webhook Guard helps record received events, matched integrations, delivery attempts, retry activity, duplicate classification, and invalid-signature evidence. It does not replace downstream application logs or ERP reconciliation.
