FAQ
How does payload diffing work?
Each incoming webhook payload is stored and its JSON schema is extracted. When a new payload arrives for the same endpoint, we run a structural diff and flag added, removed, or type-changed fields.
When do I get alerted?
Alerts are sent via Resend email the moment a breaking change is detected — removed fields, type changes, or renamed keys — so you can act before your integration fails.
Which webhook providers are supported?
Any provider that sends HTTP POST webhooks — Stripe, GitHub, Shopify, Twilio, and more. You point your webhook URL at us and we handle the rest.
