How to Integrate a Hotel API, Complete Guide

Prerequisites

• A booking engine or search product that needs hotel inventory.
• A commercial relationship with at least one supplier (or a Vervotech account to skip per-supplier commercial).
• Backend engineering capacity to consume REST APIs and cache responses.

Step 1: Pick your supplier(s)

The right supplier depends on your buyer type and geographic focus. For B2B travel agencies, bedbanks like Hotelbeds and WebBeds are usually first choice. For consumer-facing metasearch, OTAs like Expedia Rapid and Booking.com fit. For corporate travel, GDS like Amadeus and Sabre matter.

Step 2: Sign commercial and get sandbox access

Direct: negotiate contract, get credentials, receive sandbox URL and API docs. Typical time: 2-6 weeks.

Via Vervotech: sign up for the trial, receive credentials immediately, sandbox access to every mapped supplier included.

Step 3: Authenticate and call the search endpoint

Authentication patterns vary: API key + secret, OAuth 2.0, HMAC signature. Follow the supplier documentation exactly. Test with a known destination and date range.

Step 4: Handle content and rates separately

Static hotel content (descriptions, images, amenities) changes weekly to monthly. Cache it in your database. Availability and rates change per request; do not cache beyond the supplier-recommended TTL.

Step 5: Test the full booking flow

Execute search, pre-book price check, booking creation, confirmation retrieval, and cancellation in sandbox. Log every response and every error code.

Step 6: Move to production

Some suppliers require certification before production access. Once certified, switch credentials, deploy, and monitor error rates and booking success rates for the first 30 days.
