What is a Hotel CRS API?

A Hotel CRS API (Application Programming Interface) is a set of programming instructions that allows external systems to access and interact with the functionality of a Hotel CRS. This allows third-party software, such as a hotel’s website or a PMS, distributed OTAs, and internal reservation services, to communicate with the CRS and update room inventory, rates, availability, guest information, and reservations in real-time.
