Build your hotel's own channel manager with the ONDA Connectivity API.
With the ONDA Connectivity API, anyone can build their own channel manager without separate OTA contracts. (Developers Center →)
Bidirectional Integration
A single integration lets data flow both ways between your PMS and ONDA — push content, rates, and inventory; receive reservations via webhooks.
Per-Channel Differential Control
Set different prices, inventory, or open dates for the same room across channels — applied simultaneously with a single API call.
Keep Operational Control
Your UX, your pricing, your sales policy — all stay with you. Only the channel infrastructure is abstracted into ONDA.
54,416 Connected Properties
The base of Korean supply. The moment your PMS plugs in to ONDA HUB, you share the same infrastructure.
75 Sales Channels
Reach search engines, global OTAs, domestic OTAs, open markets, B2B corporate stores, and mobility — with a single line of API call.
9 Years of Operating Track Record
Battle-tested stability on top of hundreds of channel contracts and hundreds of thousands of lines of integration code. Mutual NDA and SLA included.
