**The problem it solves** Vacation rental software vendors need to connect with dozens of property management systems to reach the full market, but building and maintaining individual PMS connectors consumes engineering resources that should go toward core product development. **What Calry does** Calry is a unified API infrastructure platform that lets vacation rental software vendors integrate with 40-plus property management systems (including Hostaway, Guesty, and Hostfully) through a single standardized connection. **How it works** The Calry API covers core PMS data models: reservations, listings, availability, rates, guests, and operational events. It continuously syncs with each PMS and delivers updates via webhooks. Authentication is handled centrally with a native 1-click integration experience for end customers, including OAuth token management. Passthrough requests allow direct access to PMS source system endpoints not yet unified. API security and governance tooling, account management with automated issue detection, and an app marketplace layer for vendor discovery are included. Vendors ship integrations in weeks rather than months and eliminate ongoing connector maintenance. **Who it's for** Software companies building tools for the STR sector (guest experience platforms, revenue management tools, housekeeping software, analytics vendors) that need broad PMS reach without a dedicated integration engineering team.
