Stripe Webhooks Setup Guide
Setting up Stripe webhooks in 2026 correctly from the start saves hours of debugging later. The four steps: (1) create an endpoint in your Stripe Dashboard with the correct URL and event types, (2) copy the webhook signing secret and store it in your environment variables, (3) write a handler that verifies the signature using `constructEvent()` before processing, and (4) test with the Stripe CLI before going to production.
Why This Happens
- Configuration gaps between tools or services
- Missing integrations or manual workarounds that weren't designed to scale
- Changes in vendor behavior, pricing, or API that weren't communicated clearly
What To Check First
- Verify your current setup matches the vendor's latest documentation
- Look for recent changes — platform updates, new team members, configuration drift
- Check if the problem is consistent or intermittent (different root causes, different fixes)
When To Escalate
- The problem is costing you money or customers per week
- You've spent more than 2 hours on it without progress
- A vendor quoted you more than $500 and you're not sure if it's necessary
Dealing with this right now?
The Stripe CLI makes webhook development dramatically faster: `stripe listen --forward-to localhost:3000/webhook` creates a secure tunnel and forwards all test events to your local server. Use `stripe trigger payment_intent.succeeded` to fire test events without making real transactions. When deploying to production, use a different webhook secret (each endpoint has its own signing secret — production and test secrets are different). Never hardcode secrets — always use environment variables.
