Write role required. ## OpenAPI ````yaml /openapi.json post /admin/api/projects/{pid}/webhooks/{id}/versions openapi: 3.1.0 info: title: Hookie API version: 1.0.0 summary: Capture, route and deliver webhooks. description: >- Hookie exposes three HTTP surfaces. **Ingest + streaming** is the public plane. A path-form endpoint URL authenticates by its own high-entropy slug — there is no key, token or cookie — and an `ik_live_…` ingest key authenticates the `/v1/*` routes. Whenever the URL names a dataset the payload is stored whole into it; project mapping rules are evaluated on exactly one shape, `POST /v1/ingest/{ingest_key}` with no dataset segment. **The customer portal API** is a separate, token-authed surface for your end customers, scoped to one portal and one customer. **The admin API** drives the console. It accepts either a browser session or an OAuth bearer token from a connected coding agent — the same routes, the same validation, the same audit trail. An agent's authority is its user's workspace role narrowed to the scopes granted in the console. This document is generated from the request handlers and adversarially verified against them. contact: name: Hookie url: https://hookie.ai license: name: Proprietary url: https://hookie.ai/legal/terms servers: - url: https://app.hookie.ai description: Production - url: https://app.preview.hookie.ai description: Preview security: [] tags: - name: Ingest description: Send events to Hookie. - name: Streaming description: Tail events in real time over SSE or WebSocket. - name: Portal description: Token-authed surface for your end customers. - name: Projects description: Projects and their settings. - name: Routing description: Rules, endpoints, datasets and records. - name: Delivery description: Destinations, deliveries and replay. - name: Workflows description: Multi-step workflows, triggers and AI agents. - name: Observability description: Search, correlation, stats and the audit log. - name: Workspace description: Members, connected agents, SSO and billing. paths: /admin/api/projects/{pid}/webhooks/{id}/versions: post: tags: - Webhooks summary: Publish a new version of a webhook description: >- Top-level alias: POST /admin/api/webhooks/{id}/versions.
