Webhook Studio
Ground truth for AI-written integrations

The types are from your real traffic. Not a guess.

Point any provider at Webhook Studio. It captures the real events, learns their exact shape from your account’s own traffic, and hands you — or your agent — verified types, breaking-change diffs, and byte-faithful replay. Over a REST API and MCP built to be driven end to end.

$ curl .../v1/schemas/<id>/types?lang=typescript

// derived from 1,204 real payment_intent.succeeded events
export interface PaymentIntentSucceeded {
  id: string;
  amount: number;
  currency: string;
  status: "succeeded";
  customer: string | null;      // null in 12% of events
  metadata: Record<string, string>;
}
The optional and nullable fields are the ones that were genuinely sometimes absent in your traffic — not what a model half-remembers from the docs.

Learn the shape
Every event updates a durable schema of what the provider actually sends your account. Generate TypeScript from real payloads, diff versions, and catch breaking changes — knowledge that outlives the events.
Capture & inspect
Every request is stored with full headers, raw body, source IP, and signature result — searchable and live-updating in the Inbox, over a REST API and MCP built for agents.
Route & forward
Forward matching events to your backend with AND/OR conditions and durable retries — a delivery interrupted by a crash is re-driven, not silently lost.
Replay & prove
Re-send any captured payload to localhost byte-for-byte — original signature intact, or re-signed with your own secret so your real verification code runs unmodified.
