The `OTA_HotelInvNotif` (HIN) endpoint is now under deprecation for Home providers
The `OTA_HotelInvNotif` (HIN) endpoint was deprecated for Home providers in December 2024. We will sunset this endpoint for Home providers on **December 31, 2026**. For more information on the deprecation and sunsetting timeline, see [OTA_HotelInvNotif (HIN) endpoint in Content API](/connectivity/docs/deprecation-policy/deprecation-and-sunsetting#ota_hotelinvnotif-hin-endpoint-in-content-api-for-home-providers).

We strongly encourage Home providers to implement the [Rooms API](/connectivity/docs/rooms-api/introduction-to-rooms-api) and the Facilities API (the [room facilities](/connectivity/docs/content-api-modules/facilities-api/manage-room-facilities#managing-room-facilities) and [bathroom](/connectivity/docs/content-api-modules/facilities-api/manage-bathrooms#managing-bathroom-facilities) endpoints) at their earliest convenience.

To learn more about our new modular APIs, see our guide on [Making property onboarding easier](https://connectivity.booking.com/s/solution-article/content-api-modernisation-MCP2RH5PDI6VHN5HU3ECL2FER2TY?language=en_US).

* Room type and rate plan API: You can use the endpoint to [create, modify, or remove room types.](/connectivity/docs/room-type-and-rate-plan-management/managing-room-types/#what-falls-under-managing-room-types)
