Webhook Guardian is a SaaS tool that monitors Stripe, Shopify, and GitHub webhook delivery failures by polling delivery logs every 5 minutes and alerting engineers via Slack or email with the full payload and a one-click replay link — without sitting in the delivery path.
What is Webhook Guardian?
Why we built this
Webhooks fail silently. Stripe retries for 72 hours before giving up. Shopify drops events with no notification. GitHub stops delivering to your CI endpoint and you find out when a customer notices their provisioning didn't happen.
Webhook Guardian is the layer between "it worked in testing" and "your customer found the bug." We poll the delivery logs that Stripe, Shopify, and GitHub already maintain — every 5 minutes — and fire an alert the moment something goes wrong.
How does Webhook Guardian monitor webhooks?
We connect to your platforms via read-only OAuth and poll their native delivery log APIs. We never sit in your webhook delivery path, never act as a proxy, and never require DNS changes. Your infrastructure is completely unchanged — we're a sidecar observer, not a middleman.
Which platforms does Webhook Guardian support?
We currently monitor delivery logs from Stripe, Shopify, and GitHub. Twilio and Paddle are in development. Each integration connects via its platform's official OAuth flow and requests the minimum read-only scopes needed to read delivery history.
What happens when a webhook fails?
Within 5 minutes of detecting a failure, we send a Slack alert (Block Kit format) and/or an email containing the event type, error code, retry count, full payload, and a direct link to replay the event from your platform's dashboard. On Business plans, PagerDuty alerts are available.
