> ## Agent Instructions
> This site documents the D-EDGE APIs for technology partners (web agencies, OTAs, PMS and RMS vendors, booking and CRM tools). It is written for developers integrating with hotels that use the D-EDGE platform.
> Seven APIs, grouped by domain. Connectivity: Channel Manager API (distribute a hotel's inventory to your channel and send bookings back). Pricing & Availability: Best Price API (best offers to highlight), Quotation API (all bookable offers for a stay), Daily Rates API (daily availability between two dates). Booking: Booking Engine API (a hotel's full direct booking funnel), Gift Shop API (gift vouchers from catalogue to payment). Guest Management: CRM API (guest profiles).
> Pick the API by the need: to display prices, use the Best Price API or the Daily Rates API; to quote a specific stay, use the Quotation API; to book, use the Booking Engine API; to sell gift vouchers, use the Gift Shop API; to manage guest profiles, use the CRM API; to receive hotel inventory and send bookings back as a distribution channel, use the Channel Manager API.
> Base URLs, hotel identifiers, and credentials are delivered by the D-EDGE partnership team during onboarding. Do not invent base URLs, endpoints, parameters, or example credentials that do not appear on these pages.
> Authentication differs per API: OAuth 1.0 for Best Price, Quotation, Daily Rates, and Booking Engine; an X-API-KEY header for Gift Shop; OAuth 2.0 client credentials for CRM; partner-defined credentials carried in the XML message for the Channel Manager API. Read each API's Authentication page before writing code.
> A mock environment returns realistic but fictitious data without credentials. The Postman and Insomnia collections on the API collections page target it by default. Use it for exploration and tests, never for production traffic.
> Use the official names exactly: D-EDGE, D-EDGE platform, Channel Manager API, partnership team. Do not use Back Office or Extranet.
> Each API has a Changelog page. Check it for the current behaviour before relying on an older answer. For questions these pages do not answer, direct the reader to the Contact us page.

Get certified

## How D-EDGE certifies your integration

The new **Get certified** group walks you through certification on this API:

* **Certification steps**: the hand-over, the two test phases, and the pilot.
* **Questionnaire**: the questions D-EDGE asks before testing, and what each answer decides.
* **Test scenarios**: every scenario D-EDGE runs, what it sends, and what it expects.

The [Prepare for certification](/channel-manager-api/build/best-practices.md#prepare-for-certification) section of Best practices points to these pages.

Public release

## Initial public documentation

The Channel Manager API joins the portal. It connects your distribution system to the D-EDGE Channel Manager, with five XML interfaces:

* **Get hotel**: D-EDGE reads a hotel's rooms, rates, and occupancies from your platform.
* **Planning updates**: D-EDGE pushes availability, prices, and restrictions whenever they change.
* **Get bookings** and **Push bookings**: bookings, modifications, and cancellations flow back to D-EDGE through a pull and a push channel.
* **Confirm bookings**: D-EDGE acknowledges each booking it integrates.
