Auto-learned baselines
No need to write JSON Schema by hand — WebhookScout infers a contract from production traffic.
Schema Drift & Contract Validation
Catch breaking schema changes before they ship.
Lock the contract, learn from real traffic, and surface drift the moment a provider quietly renames a field.

What you actually get
Pin the expected shape of an event — manually, from a JSON Schema, or by learning from production traffic — and WebhookScout will alert you the instant a delivery drifts. Required field disappeared? New enum value? Type narrowed from string to number? You will know in seconds, not after the third support ticket.
- JSON Schema, OpenAPI, or learned baselines
- Severity-classified drift alerts (breaking, additive, cosmetic)
- Per-event-type and per-provider contracts
- Replay-able drift incidents for proof-of-fix
Why it matters
Built for the moments where minutes turn into hours.
Drift alerts that matter
Granular signal: required, breaking, additive, or cosmetic changes — each with a clear severity.
Per-provider contracts
Track separate contracts for each provider, each event type, even each tenant.
Use cases
What teams ship with this.
Real situations where schema validation replaces an afternoon of detective work with a single, decisive answer.
- 01
Stripe quietly added a field — get an additive-drift alert and update the type before it propagates.
- 02
A GitHub upgrade breaks one event type — see exactly which event, which field, in 30 seconds.
- 03
Catch a regression introduced by your own backend mid-deploy.
