Welcome to Holiday Extras
Holiday Extras is the UK market leader for airport hotels and other travel ancillaries including airport parking, lounges, insurance, resort transfer and car hire.
The purpose of this documentation is to enable you to quickly on-board with our API, so you can start searching for and booking our products in just a few hours.
Partner API 2026 (APIConnect)
Partner API 2026 (APIConnect) is the next step for our platform. It brings UK and EU integrations together in one place, with OAuth 2.0 authentication and standardised contracts defined using an OpenAPI schema. The platform is built to scale as we expand into more markets.
Further features, including a booking list capability to support reconciliation and recovery flows, as well as wider product coverage, will be introduced in later phases. Full technical documentation and migration guidance will be shared ahead of launch.
If you would like to learn more or discuss early access, please contact your account manager or the person who supported you with your implementation.
