Quick answer
A webhook delivery can appear successful even though the destination never created the expected record. Inspect the response and any redirect, then verify the receiver's processing result. WooCommerce's current webhook guide treats 2xx, 301, and 302 responses as non-failures for its automatic-disabling logic. That does not establish that your CRM or fulfillment system stored the event.
Define success at the right layer
Write down the required business result before debugging: a specific order record, a stock update, or a support task. Give it a stable source identifier. Then separate four checkpoints: the event occurred, an HTTP request was sent, the receiver accepted it, and the destination applied it.
An acknowledgement may mean the receiver queued work for later. A generic 200 HTML page may belong to a login screen or a website redirect, not the integration handler. A transport status is useful evidence, but it cannot replace a lookup for the promised business record.
Inspect the configured destination
Read the webhook Delivery URL in WooCommerce and compare it with the receiver's documented endpoint. Check hostnames, path prefixes, trailing-slash behavior, and HTTP-to-HTTPS redirects. Do not forward a real order payload to a guessed endpoint or a public request-inspection service.
Ask the receiver owner whether the endpoint moved. A website migration may preserve browser navigation through a redirect while breaking the original webhook contract. Request-method handling and authentication can differ across redirects. Record the actual observed route rather than assuming every client follows redirects in the same way.
Join the store log to the receiver
Use the webhook identifier, delivery identifier, and timestamp to find the request on both sides. Keep time zones explicit. The receiver should show which handler processed it, whether authentication succeeded, and whether the payload was accepted or rejected.
If the receiver has no matching request, investigate routing, proxy, or access-control logs. If it accepted the request but no destination record exists, inspect its worker and validation results. This division keeps the WordPress team from repeatedly resending an event that is already waiting in a downstream queue.
Test with one harmless fixture
Create a fictional record in a staging store connected to a test receiver. Give the fixture a distinctive identifier that does not contain personal data. Trigger one event and record the status, response content type, receiver request ID, and final destination key.
Check the actual fields, not only that a row exists. A receiver may create a record under an unexpected account, discard an unsupported field, or quarantine the payload after acknowledging it. A destination search under the wrong environment can also make a successful test look missing.
Repair the contract without broad retries
When a redirect is the cause, change to the approved direct endpoint through the supported configuration process. When receiver validation is the cause, correct that mapping before replay. Preserve webhook authentication and HTTPS; do not disable signature checking to make the request appear accepted.
For asynchronous receivers, agree on what an accepted response guarantees and how later failures are reported. Reconcile missed records by source key before retrying. A timeout after a successful destination write is especially important: repeating it without idempotency can create a second business action.
Verify the negative path too
On a test environment, confirm that an intentionally invalid fixture is rejected or quarantined visibly and does not create a normal record. The integration should not silently convert errors into success. Keep tests free of payment, shipping, or customer-email side effects.
Finish with one valid delivery, one visible invalid-data result, and a documented recovery procedure for uncertain outcomes. Close the incident only when the store event and the destination record can be joined. A green status in the delivery list is one checkpoint, not the entire transaction.
Illustrative diagnostic example. Use your own redacted evidence.One final acceptance check
Check receiver environment labels before searching the destination. A test request accepted by a sandbox can never prove that a production record exists. Record the environment beside every request identifier, especially when the same source order number can appear in a cloned store.
When to bring in help
Ask for WooCommerce webhook diagnostics when the store and receiver show different outcomes. Bring the delivery ID, time, redacted response, and destination record key so both teams can join the same event.
