Vrbo Availability Calendar
Use the Rapid Availability Calendar API to give a snapshot of daily availability for a property
Overview
The Rapid Availability Calendar API provides a snapshot of daily availability for a given property over a period of time, which can be used to assist a guest viewing the property details page. If the guest has other stay dates in mind, or the property is not available on the selected date, they can easily see when they could revise their search criteria to find availability. The Availability Calendar API will also return the minimum stay requirement for the property, and an explanation for why a given date is ineligible for check-in/out.
Note: Maximum stays are limited to Rapid’s 28 night limit.
