All chains support this. #### **Example cancel request:** ```xml ``` #### Example Cancel response: ```xml ``` * A successful Cancel response will contain a CancellationNumber="1809822537". * In the case of a reservation for multiple rooms made through a single transaction (i.e., the confirmation number covers multiple rooms), the cancellation request cancels ALL rooms under that confirmation number, and the cancellation number applies to ALL rooms. * Where multiple rooms exist under a single confirmation number and the desire is to cancel one room only, the options are to use “Modify Reservation” or to cancel the original reservation and re-book the remaining rooms. * It is not possible to cancel a reservation booked through a distributor with a different SGA code. * When using the optional attribute Title in the booking request, this will need to be passed in the cancel request or the cancel will fail. * Demand Partners need to store the confirmation number, property id, the guest name, and stay dates internally as this is not retrievable through RateGain and is required to modify or cancel. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://developer.rategain.com/ultradirect/ultradirect-transaction-samples-and-usage/cancellation.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
