Reservation calls allow a third party application to create, modify, or cancel a housing reservations. These messages are based on the OpenTravel (OTA) standards and the order in which these messages are used must be followed. For example, you cannot use the create reservation call to modify an existing reservation. It is also important to note that once a reservation is canceled, it cannot be made active again (reinstated). Many of the required elements for reservation messages can be received from the response from an availability call.
