Holidu is a Munich-based vacation-rental search engine and short-term-rental technology company that helps travellers find and book holiday homes and helps property owners and managers distribute their inventory. Holidu exposes a public Developer Hub with two production REST APIs: the Affiliate API, for searching offers, retrieving property details, checking real-time availability and syncing changes; and the Connectivity (provider) API, a v2 property-management surface of ~50 operations covering apartments, multi-unit listings, descriptions, photos, facilities, reviews, rates, length-of-stay pricing, availability, extra costs, discounts, booking terms, payment and cancellation configuration, and bookings. Authentication is via per-partner API keys (with an OAuth 2.0 security service and Bearer-JWT callbacks), sandbox and production hosts are separated, and Holidu runs a HackerOne bug-bounty program. Holidu is backed by EQT Ventures, HV Capital and Northzone.
