# General design

**Reservation Notification Process**:

* **OTA\_HotelResNotifRQ**:
  * OTA will push the bookings to DirectConnect using the reservation notification request message `OTA_HotelResNotifRQ`.
  * Each reservation notification request will hold a single reservation record.

**Response from DirectConnect**:

* DirectConnect will send either a success response or an error response with reasons for failure.

**Handling Different Reservation States**:

* **Commit, Modified, and Canceled Reservations**:
  * All types of reservations (commit, modified, and canceled) are pushed by sending an `OTA_HotelResNotifRQ` message.
  * DirectConnect responds with an `OTA_HotelResNotifRS` message.

## 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.

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/our-products/channel-manager/direct-connect-demand-push/interface-specifications-reservation-notification-service/technical-overview/general-design.md?ask=<question>&goal=<endgoal>
```

`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.
