# Points to remember #### OTA\_HotelAvailNotifRQ Operation **Usage**: * The `OTA_HotelAvailNotifRQ` operation is used to send both Inventory (BookingLimit) and Restrictions (Arrival/Departure/Master Status/LOS restrictions/AdvPurchase) updates. * Allocation/InventoryCount/BookingLimit is manageable at the room level only by a CRS/PMS partner. **Separate Messages for Inventory and Restrictions**: * If both inventory and restriction need to be updated for the same room type and date, two separate messages must be sent to the RG Bridge ARI service. Partners should implement this use case accordingly. **Compact ARI Updates**: * ARI updates for a range of dates should be prepared compactly, covering multiple days using `StartDate` and `EndDate` in a single element (i.e., `AvailStatusMessage` / `RateAmountMessage` block), if the same ARI data needs to be updated for a range of dates. **Delta Updates Recommendation**: * Partners should always send delta updates after a full refresh is made initially for a new hotel connected to the interface. * Example: If a booking/cancellation is made for a particular HotelProduct (RoomType + RatePlan), partners should send updates for the corresponding HotelProduct and specific dates affected by the new booking/cancellation. * It is not allowed to send updates for all HotelProducts or larger date ranges that are not part of the recent booking/cancellation received for a hotel. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
