Hospitable Messages API

info:
  title: Hospitable Public Calendar Messages API
  description: The Hospitable Public API (v2) is a REST API for short-term and vacation rental hosts, property managers, and vendors. It exposes the core objects of the Hospitable platform - properties, channel listings, reservations, guest messages, calendar availability and pricing, and reviews - as resources manipulated with conventional HTTP methods (GET, POST, PUT, PATCH, DELETE) over HTTPS. Versioning is in the URL path (e.g. /v2/properties). Requests are authenticated with a Bearer token that is either a Personal Access Token (PAT) for personal use or an OAuth 2.0 access token for vendor integrations; PATs have access to all endpoints by default. Read access covers properties, reservations, and calendar; write access covers property calendar pricing and availability and sending guest messages. Hospitable was formerly known as Smartbnb. Note - the exact request/response schemas below are modeled from Hospitable's public documentation and community SDKs; verify field-level details against developer.hospitable.com.
