Fixing Stripe Webhook Failures

When Stripe webhooks fail, invoices and subscriptions stop syncing. Here is the short checklist we use to fix them fast.

1. Verify the endpoint URL

Confirm the endpoint is live, uses HTTPS, and points to the correct environment (test vs live).

2. Check signature validation

Most 400 errors happen because the webhook signing secret is wrong or not loaded.

3. Reduce response time

Stripe expects quick responses. Move heavy work to a queue and return 200 fast.

4. Re-send failed events

Use Stripe dashboard to replay failed events and confirm your fixes.
