Stripe BillingStripe: webhook events fail to deliver to your endpoint

Rather not fix it yourself? Stripe Billing Fix and Setup handles it at a fixed price, agreed before work starts.

Why Stripe can’t deliver the event, and the fix

1. 01

   The URL redirects

   “We consider redirect responses to webhook requests as failures.” Stripe, Debug webhook deliveries

   http to https, the bare domain to www, or a missing trailing slash all send a redirect. Save the exact final URL as the endpoint.

2. 02

   Your app blocks the request

   “you might need to exempt the webhooks route from CSRF protection.” Stripe, Webhooks (CSRF)

   A 401 or 403 usually means login middleware, deployment protection on a preview URL, or CSRF checks. A 405 means the route doesn’t accept POST, and a 404 means the path is wrong. Make the endpoint public and let POST through.

3. 03

   The handler times out

   “Make sure you defer complex logic and return a successful response immediately in your webhook handling code.” Stripe, Debug webhook deliveries (timed out)

   Sending emails or updating several systems before you respond can run past the time limit. Save the event, return 200, then do the work. On serverless hosts, work after the response may be cut off, so run it from a queue or a scheduled job.

   app.post('/webhooks/stripe', express.raw({ type: 'application/json' }), async (req, res) => {
     let event;
     try {
       event = stripe.webhooks.constructEvent(req.body, req.headers['stripe-signature'], process.env.STRIPE_WEBHOOK_SECRET);
     } catch (err) {
       return res.sendStatus(400);
     }
     await saveEvent(event);
     res.sendStatus(200);
     processEvent(event.id).catch(console.error);
   });

4. 04

   Events were missed while it was down

   “Set to false to return only events that failed delivery to at least one of your endpoints.” Stripe, Process undelivered events

   After the fix, list the failed events and run them through your handler, skipping any event ID you already processed. Stripe returns only events from the last 30 days, and 10 per page by default, so page through the rest.

   const failed = await stripe.events.list({ delivery_success: false, limit: 100 });
