G-Link Hotel API Overview

G-Link Hotel API provides hotel discovery, real-time product availability, booking, payment, order management, and status notifications through Open Platform.

Before you start

1. Create and activate your application in the target environment. Sandbox and production credentials are separate.
2. Obtain your App Key and App Secret. Never expose the App Secret in client-side code or documentation.
3. Add the outbound IP address to the allowlist when required.
4. Implement the HMAC-SHA256 request signature before calling any API.

Choose an integration path

Lightweight Integration

Recommended for a faster launch. Discover destinations and hotels in real time, then request product availability when the traveller enters the booking path.

Standard API Integration

Recommended when you maintain a local hotel catalogue and mappings. Synchronize saleable hotel IDs and static hotel data before selling.

Recommended next steps

• Read Authentication & Request Signing.
• Choose an integration flow.
• Complete a sandbox request before beginning booking integration.

Important: Business success is determined by the response code field. Do not rely on the HTTP status alone.
