# Booking Accommodation API Changes

## What is changing?

We are updating our API to modify a key value. Effective from 22 October 2024, the key "numOptionsPerRoom" will be changed to "numOptions" in the [getBookingAccommodationList](/venues/accommodation/get-booking-accommodation-list.md) and [addOrUpdateBookingAccommodation](/venues/accommodation/add-or-update-booking-accommodation.md) endpoints.

## How might you be affected?

If you currently use the [getBookingAccommodationList](/venues/accommodation/get-booking-accommodation-list.md) and [addOrUpdateBookingAccommodation](/venues/accommodation/add-or-update-booking-accommodation.md) endpoints, please be aware that the key "numOptionsPerRoom" will no longer be recognized.

## What is changing in the iVvy API?

* [getBookingAccommodationList](/venues/accommodation/get-booking-accommodation-list.md)
* [addOrUpdateBookingAccommodation](/venues/accommodation/add-or-update-booking-accommodation.md)

The key "numOptionsPerRoom" will be replaced with "numOptions".

## What should you do?

Please update your applications and integrations to use the new key "numOptions" in place of "numOptionsPerRoom" for the [getBookingAccommodationList](/venues/accommodation/get-booking-accommodation-list.md) and [addOrUpdateBookingAccommodation](/venues/accommodation/add-or-update-booking-accommodation.md) endpoints.
