FAQ

How does schema diffing work?
Each incoming payload is analyzed to infer a JSON schema. We compare it against the previous schema for that endpoint and flag any removed fields, changed types, or structural regressions as breaking changes.
Which webhooks can I monitor?
Any HTTP webhook — Stripe, GitHub, Shopify, Twilio, or your own internal services. Just point the source at your unique monitor URL and we handle the rest.
What happens when a breaking change is detected?
You receive an immediate alert via email or Slack with a side-by-side diff showing exactly what changed, so you can fix integrations before they cause downtime.
