• Some channels like Naver, Kakao, and Goodchoice allow transferring existing information and reviews.

Transfer time depends on channel policies — as fast as 1 day, up to 10 business days. Once connected, you can manage all channels from a single system, making the initial investment highly efficient.

A channel manager is a tool that lets you manage multiple online sales platforms (OTAs) through a single system.

With ONDA's channel manager: - Manage inventory (rooms), pricing, and content (photos, descriptions) across channels from one place - Changes made in one place are automatically reflected across all connected channels - Phone or messenger bookings can be manually registered for unified management

No need to log into each channel separately—saving significant operational time.

ONDA has directly integrated 70+ channels over 9 years. All channels are Live with millions of bookings processed annually in real time. Eight categories:

• Global OTAs · Metasearch (8) — Booking.com, Airbnb, Trip.com, Agoda, Fliggy, Google Hotel, HotelsCombined, AllStay
• Korean OTAs · E-commerce (12) — Goodchoice (여기어때), Naver, Coupang, 11st, SSG, Gmarket, Kakao, Hana Tour Business, Noranbubble, Tonight, etc.

By the numbers: 70+ channels · 48,000+ connected properties · 2M+ bookings/year

A single contract lists you on all channels simultaneously, with new channels continuously added. Korean OTAs, B2E corporate marketplaces, and regional tourism portals — areas where global channel managers are weak — are ONDA's 9-year operational moat.

Yes, they are automatically blocked.

When a booking occurs on any channel, ONDA's system automatically deducts inventory across all connected channels within 2 seconds. You can operate with confidence, free from overbooking worries.

No. Just make changes once in the ONDA partner page, and they're automatically synced across all connected channels.

Photo updates, room description edits, rate changes, inventory adjustments—just modify in one place and you're done.

Tax Related: - Sales data for VAT filing can be downloaded in Excel (monthly / quarterly / semi-annually)

It depends on the channel:

By opening through ONDA, your property gets simultaneously listed on numerous domestic and international channels. This exposes your property to a much wider range of travelers compared to relying on a single channel.

Additionally, through the booking engine, you get direct exposure on Google Hotels and AI searches.

The AI phone assistant launches Korea-first when ONDA Plus officially launches as one of its five modules (launch date to be announced).

How it works: - When guests call your property, ONDA's AI assistant handles the call in Korean or English - Quotes available rooms and rates, check-in time, arrival guidance - Hands off seamlessly to the booking engine when payment/confirmation is needed - Escalates to operator's mobile if unanswerable

Why it helps: - Captures booking opportunities outside business hours - Reduces the burden of handling foreign-language inquiries - Call transcripts and summaries available in the partner dashboard

Included in Pro and Premium plans. Other regions will roll out in phases.

OTA Guest Reply is an ONDA Plus module that auto-responds with AI to guest messages, inquiries, and reviews on Booking.com · Agoda · Expedia · Trip.com and other major OTAs.

Handles: - Check-in/check-out time inquiries - Facility info (parking, Wi-Fi, breakfast, etc.) - Arrival guidance and location questions - Thank-you messages for reviews

Why it matters: - Fast response = decisive for OTA ranking algorithms - 100% response rate even on weekends and overnight - Frees operators from repetitive inquiries to focus on core operations

Included in Pro and Premium plans, with three tone levels (Basic/Pro/Premium) adjustable to match your property's brand.

Global channel managers excel at global OTA integration but have weak coverage of Korean channels (Yanolja, Goodchoice, domestic B2B corporate marketplaces).

ONDA has focused on the Korean market for 9 years and built 70+ channels + 48,000+ property inventory with native Korean operational support.

→ For the Korean market, ONDA is the fastest path — global OTAs + Korean OTAs + domestic B2B in one integration.

First reference: an IT subsidiary of a domestic hotel chain — 150 directly operated hotels, going live July 2026.

A hybrid integration case combining the customer's own CMS with the ONDA Vendor API.

Additional cases will be disclosed from Q3 2026. After NDA, we share anonymized cases — segment, property scale, challenges, outcomes — in detail during sales meetings.

Yes, ONDA provides a RESTful API.

What you can build with our API: - Property search and lookup - Real-time pricing / inventory check - Booking creation and management - Payment processing

API documentation and technical support are available at the ONDA Developer Center.

ONDA MCP is an LLM-native integration method that enables AI agents and chatbots to process accommodation bookings in natural language.

Usage Examples: - "Find a 2-person accommodation near Gangnam, Seoul" - "Book a pension in Jeju this weekend" - "Compare hotel prices in Busan for 3 nights"

Optimized for AI service development over traditional REST APIs, ideal for developers building their own AI travel services.

Yes, ONDA's booking engine and websites are designed to be LLM-friendly.

Applied Technologies: - Automatic Schema.org structured data - AI crawler access (GPTBot, Claude-Web, etc.) - llms.txt standard support

This ensures accurate property information appears in AI searches like ChatGPT, Claude, and Perplexity, allowing you to reach travelers who receive accommodation recommendations through AI.

ONDA guarantees 99.9% service uptime.

We maintain service stability through a 24-hour monitoring system and respond promptly to any incidents.

API integration is ideal when you want to fully integrate ONDA's property data and booking features into your own service. ASP is suitable when you want to provide accommodation booking services without development.

Yes. You can build your own channel manager and start operating with officially integrated OTAs immediately.

We open the 70+ channel infrastructure ONDA built over 9 years as a single standard API set. A hotel SaaS startup launching its own-brand channel manager in 6 weeks is an actual scenario.

👉 [Build your own — `/developers/connectivity-api`](https://global.onda.me/en/developers/connectivity-api)

It works over standard HTTP REST + JSON, so it's callable from any language or framework.

From the OpenAPI 3.1 spec, you can auto-generate client code in nearly any language — Java, TypeScript, Python, Go, etc. Auth is Bearer token, and webhooks are plain HTTP POST so the receiving side is implementation-free.

👉 API docs: [`vendor.dapi.tport.dev`](https://vendor.dapi.tport.dev/docs/thehyoosik)

Currently we provide a 1:1 sandbox account after NDA following a sales meeting.

By Q4 2026 we'll have a self-service sandbox → automatic API key issuance → interactive docs demo. Until then, 1:1 ONDA PM support delivers the same effect.

API communication is protected via HTTPS + Bearer token. Data is processed in-transit only and not permanently stored at ONDA.

Webhooks operate over standard HTTP POST and are backed by 9 years of operational reliability. Our standard SLA specifies availability %, recovery time, and liability cap.

API and tech-asset IP belongs to ONDA, while the partner's sales · customer · operational data IP remains the partner's asset.

The standard contract includes a mutual NDA for 5 years, and on termination, a reasonable transition period is guaranteed for channel mapping and booking data export. No lock-in.
