Read-only: nothing is joined, spent or written, and like accept it is resolved WITHOUT the automatic workspace every other admin route creates for someone who has none. The console shows this (the workspace, who sent the invite, the role) and joins only when the person clicks Join, so opening a link from anywhere never moves them into a workspace by itself. It is a POST so the token travels in the body, not the URL. Every token that accept would refuse as not found (wrong, expired, revoked, used by someone else, or whose creator could no longer create it) answers the same 404 with the same words. Whether the workspace is full or suspended is decided when joining. ## OpenAPI ````yaml /openapi.json post /admin/api/invites/preview 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. An endpoint URL files each payload into the endpoint's own dataset through the endpoint's own criteria and mappings (none means the whole payload, as one record); `/v1/ingest/{ingest_key}/{dataset}` stores the payload whole into the named dataset. Project mapping rules are evaluated on exactly one shape, `POST /v1/ingest/{ingest_key}` with no dataset segment, and never on an endpoint URL. **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. It also accepts an **admin API key** (`hk_…`, Settings → API keys) for CI, infrastructure-as-code and vendor backends: the key acts as the member who created it, capped at the key's role (viewer, developer or admin — never billing or platform administration), optionally limited to one project, with an optional expiry and IP allowlist. Keys are stored as a SHA-256 hash and shown once; if their creator leaves the workspace they stop working. The same key works on the hosted MCP server at `/mcp`. **A refused agent is told how to proceed.** An agent's grant is one rung of a ladder — `hookie:read` < `hookie:write` < `hookie:manage` — and a call above it answers 403 with `code: "agent_scope_insufficient"`, the `required_scope`, the `granted_scopes` and a `manage_url` to the console page where its user widens it. When the user's own role is the limit the code is `insufficient_role` and there is no link, because no grant can exceed the user; billing, platform admin, managing connected agents and destination signing secrets answer `agent_not_permitted` at every scope. A human in the console still reads `Insufficient role`. **A suspended workspace** (an operator action, for abuse or non-payment) answers every surface with 403 and `reason: "workspace_suspended"`: ingest (endpoint URLs and ingest keys), `/v1/data` and `/v1/stream` refuse before anything is stored or counted, and every admin API write — console, OAuth agent or hosted MCP alike — is refused except billing, platform admin, connected-agent management, revoking an API key, revoking an invite, removing a member or leaving, accepting an invite to another workspace, switching workspaces and the POST-bodied searches. The customer portal API is read-only in the same way: destination writes answer 403 `workspace_suspended`. Reads keep working. Nothing is sent while it is suspended: pending deliveries are paused, workflow runs already under way are paused, open `/v1/stream` connections are closed, and cron triggers, database sources and WebSocket listeners stop. Reinstating sends the paused deliveries, resumes the paused workflow runs where they stopped, and resumes the rest; no stored data is lost. **Rate limits.** `/admin/api/*` and `/mcp` allow about 100 requests every 10 seconds per credential — per API key, per connected agent, or per signed-in person. Over that, the answer is 429 with `Retry-After` (seconds). Like every burst limit here, ingest's included, it is a best-effort guard rather than an exact count: it is counted separately at each Cloudflare location and catches up within seconds, so a short burst can get through above it. The monthly event quota is the exact count. **Idempotency.** A `POST` to `/admin/api/*` may carry an `Idempotency-Key` header (1–255 printable characters, e.g. a UUID). The first request runs and its response is stored for 24 hours; a retry with the same key from the same credential, with the same path and body, gets that response back with `Idempotent-Replayed: true` and runs nothing. The same key with a different path, body or credential is refused with 422; a retry while the first request is still running gets 409. 5xx responses are not stored. `POST /admin/api/api-keys` refuses the header, because its response is a secret shown once and is never stored. **Versioning.** Every `/admin/api/*` and `/mcp` response carries `Hookie-Version` (currently `2026-09-29`). Additive changes — a new route, a new response field, a new optional parameter — ship under the current version, so clients must ignore fields they do not know. A breaking change gets a new dated version, announced in the changelog, and the previous version stays available for at least 12 months; a client pins one by sending `Hookie-Version` on its requests. A version this deployment does not serve is refused with 400 and the list of `supported_versions`. 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: >- The workspace itself: its name and slug, its members and their roles, shareable-link invites, ownership transfer, the switcher between the workspaces a person belongs to, admin API keys, data export and closure. - name: Data API description: >- Read-only access to the datasets and columns a project exposes, with per-project keys. - name: Broadcast Logs description: >- Forward a project's logs and traces over OTLP/HTTP (JSON) to Datadog, Grafana Cloud, an OpenTelemetry Collector, PostHog or Sentry. paths: /admin/api/invites/preview: post: tags: - Workspace summary: See what an invite link's token would join, without joining description: >- Any signed-in person, in the console (#308); never an agent or an API key.
