Stripe Webhooks Integration Not Working
Quick Answer
The most common root cause for this type of issue is a misconfigured integration, a missing credential, or a default setting that does not match production requirements. Start by isolating which system last touched the data before the failure.
Stripe webhook integrations fail in 2026 at four common points: registration (wrong URL or endpoint not created in the Dashboard), signature verification (using the wrong webhook secret — there are different secrets for test mode and live mode), event handling (subscribing to the wrong event names or not handling all required events), and idempotency (processing the same event twice when Stripe retries).
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 most common and destructive mistake: using the wrong webhook secret. Your Stripe Dashboard shows two signing secrets per endpoint — one for test mode and one for live mode. If your production code uses the test-mode secret, every live webhook will fail signature verification and be rejected. Check Dashboard → Developers → Webhooks → [endpoint] → Signing secret, then compare to what is in your environment variables.
