postzen-dev Webhooks API is one of 13 APIs that [postzen-dev](https://apis.io/providers/postzen-dev/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. This API exposes 6 JSON Schema definitions. Tagged areas include Webhooks. The published artifact set on APIs.io includes an OpenAPI specification and 6 JSON Schemas.

Manage outbound webhook endpoints and retained delivery logs. PostZen sends an at-least-once JSON envelope `{ id, type, apiVersion, createdAt, data }` using `POST`; automatic retries and manual redeliveries keep the same event id and raw body. Requests include `X-PostZen-Event`, `X-PostZen-Event-Id`, `X-PostZen-Delivery-Id`, and `X-PostZen-Timestamp`. When a signing secret is configured, `X-PostZen-Signature` is `v1=<hex digest>` where the digest is HMAC-SHA256 over `<timestamp>.<raw request body>`. Production receivers should configure signing, compare signatures in constant time, reject timestamps older than five minutes, and deduplicate by event id.
