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.

Expedia Group Rapid API

Expedia's lodging inventory with shop, price check, book, change and cancel in one API. Partner application and site review before production, no self-serve keys.

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

Expedia Group Rapid API

  1. Build the SHA-512 signature from key, secret and the current epoch seconds in that order, per request
  2. Send Customer-Ip and the session headers the docs ask for, since fraud checks use them
  3. Point everything at test.ean.com until the site review is through; the paths match api.ean.com
  4. Follow the links in each response rather than building URLs; price check and book links carry tokens
  5. Read the Rate-Limit-Minute-Remaining and Rate-Limit-Day-Remaining headers, since the docs publish no ceilings
