Webhook Validator
Check your Stripe webhook handling against best practice — signature verification, idempotency, retries, and dead-letter handling.
About this validator
Webhook handling is a small piece of code that carries an outsized share of billing bugs — not because the logic is complex, but because the failure modes (duplicate delivery, out-of-order events, silent drops during a deploy) are easy to overlook until they've already corrupted revenue data.
This validator checks your webhook architecture against a short list of best practices. Answer honestly, not aspirationally — an 'unsure' is more useful to you here than a guessed 'yes'.
Frequently Asked Questions
How is this different from the Stripe Integration Audit?
The audit scores your entire Stripe integration across many dimensions — webhooks, retries, pricing sync, customer data. This validator checks just webhook handling specifically, in under a minute, with an automatic verdict based on your answers rather than a self-scored checklist.
Why isn't this connected directly to my Stripe account?
Connecting your account would require OAuth access and inspecting your actual code or webhook logs — a much bigger ask for a free tool, and not necessary for a useful verdict. Answering based on how your system is built gives an accurate result without requiring access to your infrastructure.
Is my input data saved anywhere?
No. Everything is evaluated in your browser from your selections. Nothing is sent to or stored on our servers, and no account is required.
