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. # Compute merge confidence > Score how close two or more guest profiles are before merging them The computation runs in the background. The response carries no body: read the `location` header, then poll the task it points at with [Read a task](/crm-api/build/reference/merge/get-task.md). The score lands in the task's `result`. ## OpenAPI ````yaml crm-api/open-api/crm-api.json POST /api/guestprofile/entities/{entity_id}/guests/compute-merge-confidence openapi: 3.0.3 info: description: >- D-EDGE CRM Guest Profile is a CDP (Customer Data Platform). Guest Profile API allows every authenticated user or third party system to interact with D-EDGE CRM Guest Profile data.
