Webhook payload schemas

Every webhook event carries its full payload schema in the same document, under the top-level webhooks map — the OpenAPI 3.1 feature designed for exactly this.

If you have previously had to reverse-engineer webhook payloads from example JSON, this is the structured description you were missing. application_offered alone documents 17 fields.

Using it with tooling

Import → Link, then paste https://lending-api-docs.iwoca.co.uk/openapi.json. Postman generates a collection covering every endpoint.

The schema is fully dereferenced — every $ref is expanded in place, so there is no components/schemas section. Generated clients will therefore produce inline anonymous types rather than named, reusable models. If that causes you a problem, tell us.
