Stripe Webhooks Not Reaching WooCommerce
Payments were processed successfully, but failed webhook deliveries prevented orders from updating automatically.
A client's store was processing orders normally, or so it appeared. Every checkout completed, and every order appeared in WooCommerce. What wasn't visible was that Stripe was attempting to send a payment confirmation to WooCommerce after each transaction, and WooCommerce was rejecting it every time.
The store was one edge case away from losing critical payment events entirely.
A silent failure hiding in plain sight
Stripe confirms completed payments by sending webhook events to WooCommerce. WooCommerce verifies each event using a signing secret that must match on both sides of the integration.
When the signing secret falls out of sync, WooCommerce rejects the webhook. No error appears during checkout, and orders may still be created through a fallback mechanism. This masks the problem until a feature that depends on webhooks — such as refunds, disputes, or subscription renewals — fails unexpectedly.
Investigation
The first step was pulling the Stripe event delivery logs. Every webhook attempt was there — timestamp, endpoint, response code. WooCommerce was returning a 401 on every one. That told me the rejection was happening at the signature verification layer, not a networking or firewall issue.
I cross-referenced the signing secret stored in WooCommerce's Stripe gateway settings against the live secret in the Stripe dashboard. They didn't match. At some point during a plugin update or a settings migration, the stored secret had been overwritten with an outdated value. Stripe was signing events correctly. WooCommerce just couldn't verify them.
The fallback order creation mechanism had been quietly compensating for weeks, which is why the store appeared to be functioning normally. No alerts, no visible errors — just a payment integration running on a safety net nobody knew was there.
Resolution
I copied the correct signing secret from the Stripe dashboard webhook settings, updated the value in WooCommerce, and triggered a test webhook event. The 401 cleared immediately — WooCommerce returned a 200 and processed the event correctly. I ran the full Stripe test suite against the endpoint to confirm all event types were being received and acknowledged before closing the engagement.
| Metric | Before | After |
|---|---|---|
| Webhook delivery | Failing — 401 on every attempt | 100% success rate |
| Order status updates | Fallback mechanism only | Fully automated |
| Stripe event processing | 0 events acknowledged | All event types confirmed |
| Time to diagnose | — | Under 2 hours |
| Integration health | Running on silent fallback | Verified end-to-end |
Successful checkouts do not always mean a healthy payment integration. When Stripe payments succeed but WooCommerce behaves unexpectedly — slow order updates, missing confirmations, subscription issues — webhook delivery should be the first thing you check. The fallback mechanism exists for edge cases, not as a permanent operating mode.
