Stripe Webhooks Slow Performance Fix
Stripe webhook timeouts in 2026 happen when your endpoint takes more than 30 seconds to respond. Stripe marks the delivery as failed and retries. If your handler does heavy processing synchronously (database writes, sending emails, calling other APIs), it will regularly exceed this limit under load.
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 solution: decouple receipt from processing. When a webhook arrives, write the raw event JSON to a queue (Redis, SQS, a database table) and return 200 immediately — this takes under 100ms. A separate worker processes the queue at whatever speed your system can handle. This pattern handles any volume of incoming events, survives bursts, and ensures no events are lost even if processing temporarily falls behind. Never do heavy work synchronously in a webhook handler.
