RateHawk, part of Emerging Travel Group (ETG), is one of the world's leading B2B hotel booking platforms โ built for travel agents, OTAs, and tour operators. Its RESTful hotel API gives partners access to 2.9M+ accommodations across 220 countries, aggregated from 330+ suppliers plus tens of thousands of directly-contracted hotels.
The RateHawk API delivers rich multilingual content in 32+ languages, instant confirmation, and competitive net rates โ with three commercial models to choose from: net price, commission, or affiliate. It's a modern, developer-friendly REST API with a documented 4-step certification path.
RateHawk combines breadth (2.9M+ stays: city hotels, resorts, apartments, guest houses, campgrounds) with depth (directly-contracted inventory and exclusive rates). For travel agents and OTAs, it's one of the most competitive single sources of global hotel supply โ which is exactly why platforms integrate it.
This is where ZentrumHub is different. RateHawk doesn't just connect to us โ RateHawk sources hotel inventory through ZentrumHub's Zentrum Connect network too. It's a documented, bidirectional strategic partnership that drove +358% YoY booking growth and +300% partner adoption. Read the full RateHawk hotel API guide.
