Requires scope `read:channels`. ## OpenAPI ````yaml /api-reference/openapi.yaml get /v1/channels openapi: 3.1.0 info: title: Casa Layer API version: 1.0.0 description: > Headless, read-only access to the guest context layer — the entire canonical data model over HTTP. Every endpoint is **scoped by the credential**: the default scope is the caller's property group, returning data across all of its properties. Auth sources resolve to the same credential: a user-generated **API key** (`casa_…`, created in Account settings — the recommended method for first-party machines), a **partner credential** access token (third-party agents, REST-only), a session JWT (the web app; org and role come from verified token claims), or a static token. (The MCP server also accepts read-only OAuth connector tokens, but those are rejected on these REST routes.) Send `X-Property-Id` to drill one request down to a single property. Personal API keys and partner credentials accept that header. A property-pinned API key ignores it. Tenant isolation holds by construction. The Model Context Protocol (MCP) server is exposed separately at `/mcp` and is documented under **MCP Server** in the guides — it is not a REST endpoint and is intentionally omitted from this reference. It accepts the same API keys. servers: - url: https://api.casa-layer.com description: Production Cloudflare Worker security: - bearerAuth: [] tags: - name: System description: Liveness, health, and the public welcome page. - name: Guests description: Canonical guest profiles as ingested from each source system. - name: Master Profiles description: >- Identity-resolved golden records — one entity per real guest, merged across sources and properties. - name: Reservations description: >- Reservation records linked to guest profiles, searchable by status, stay window, and channel. - name: Transactions description: >- Revenue lines (Pace Transactions V2–shaped) linked to guests and optionally reservations. - name: Consents description: > Contact-grain consent observations (contact method + value × purpose).

Token types resolve to the same scoped credential: a user-generated **API key** (`casa_…`, from Account settings — recommended for first-party machines and MCP clients), a **partner credential** access token (third-party agents; REST-only), a session JWT (the web app; org and role come from verified token claims), or a static token. API keys are group-scoped, optionally pinned to one property at creation. Personal API keys and partner credentials accept `X-Property-Id` to drill down to one property in the group. A property-pinned API key ignores that header. MCP OAuth connector tokens authenticate the MCP server only and are rejected on these REST routes. ````
