Expedia Group Rapid API vs Hotelbeds Hotel Booking API

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.

Hotelbeds Hotel Booking API

Free evaluation key on registration, no card and no sales call. 50 requests a day on evaluation, and the 51st returns a 403.

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

Hotelbeds Hotel Booking API

1. Compute X-Signature fresh per request from key, secret and the current epoch seconds, in that order
2. Budget the 50 daily evaluation calls; cache hotel content and only call availability for real dates
3. Run CheckRate on a rate before booking when the availability response says it needs rechecking
4. Read a 403 on the test host as the daily quota first, not a bad key
5. Simulate a cancellation before running it
