## Which one, for what

### Booking.com Demand API (E)

Good for: An affiliate that already holds Booking.com credentials and wants its agent to book stays, cars and attractions.

Watch for: Managed Affiliate Partner status required; no self-serve key

Ahead on:
- Security & auth, 48 against 36
- Payments & pricing, 25 against 5
- Maintenance & community, 60 against 28

Watch for: Keys are issued only after an application review and a commercial agreement, with a stated minimum of 100,000 monthly active users

## Verdicts

**Booking.com Demand API.** Search, look and book plus order management on Booking.com's accommodation inventory. Managed Affiliate Partner status required; no self-serve key.

**Skyscanner Travel APIs.** Thirteen documented search APIs cover flights, hotels and car hire behind one `x-api-key` header, with default rate limits published per endpoint and no usage fee. Access needs an approved application, an audience above 100,000 monthly users and a commercial agreement, and the usage guidelines bar live-price calls made without a user action. Booking happens on supplier sites.

## Before you call either

### Booking.com Demand API

1. Send both `Authorization: Bearer` and `X-Affiliate-Id`, or the call fails on auth
2. Stay under 50 requests a minute in the sandbox and back off exponentially on 429
3. Only accommodation flows book in the sandbox; cars and attractions won't
4. Store the key at creation, it's never shown again
5. Use filters and pagination on search to keep payloads small

### Skyscanner Travel APIs

1. Send the key in the `x-api-key` header on every call to `https://partners.api.skyscanner.net`. CORS is not supported, so call from a server
2. Create a live search only when a user has given origin, destination and exact dates. Use the indicative price endpoints for open-ended questions
3. Poll `/search/poll/{sessionToken}` until `status` is `RESULT_STATUS_COMPLETE`, and replace earlier results only when `action` is `RESULT_ACTION_REPLACED`
4. Start a new session when a poll returns 400. Flight session tokens last about an hour and hotel sessions at most 15 minutes
5. Pass each `deepLink` to the traveller unchanged, since altered encoding breaks Impact tracking, and never put personal data in `subid2`
