Developer Developer Platform APIs for travel infrastructure

Build on the supply network behind travel.

G-Link and F-Link expose FCG's hotel and air supply through one connection — 4.35M+ hotel records, plus GDS, NDC & LCC air, deduplicated and bookable. Integrate by API, SDK, or Skills on the ADDN network.

API surface

Two supply APIs. One connection.

Authenticate once, search across every connected supplier, confirm bookings, and manage the full lifecycle. The supply complexity is resolved before it reaches your product.

G-LinkHotel supply

4.35M+ deduplicated hotel records. GDS, direct hotel, bedbank, and Asia-direct supply resolved into one feed — with corporate-rate routing and content normalised across sources.

GET/v2/hotels/availabilitySearch every source
POST/v2/bookings/createConfirm a reservation
GET/v2/bookings/{id}Manage the lifecycle
F-LinkAir supply

GDS, NDC & LCC through one connection. F-Link aggregates GDS, NDC direct, and LCC direct into one normalised feed, with China-route coverage through Travelsky where global air APIs fall short.

GET/v2/flights/searchGDS · NDC · LCC
POST/v2/flights/priceFare-family pricing
POST/v2/flights/ticketPNR + ticketing
Request · Response

One call queries every supplier.

Search G-Link, select a rate, and confirm — modifications, cancellations, and reporting run through the same connection.

Quickstart

Sandbox to production in four steps.

Move from a sandbox key to your first production booking — documentation, test environments, and webhook-ready workflows from the start.

01 / 04

Get your API key

Request sandbox access and receive your key and test credentials within 24 hours.

02 / 04

Read the docs

Request and response examples, authentication, error handling — or integrate by Skills and let AI write the code.

03 / 04

Make a test booking

Run a hotel search against G-Link, select a rate, and confirm a sandbox booking in a realistic environment.

04 / 04

Go live

Switch to production credentials once validated, with commercial terms and supplier activation handled in parallel.

Build on the Developer Platform

One integration to the supply behind travel.

Connect to G-Link and F-Link through the Developer Platform — by API, SDK, or Skills, on the ADDN network.

Connect every source

4.35M+ hotels across GDS, direct, bedbank, and Asia-direct — deduplicated and bookable through one endpoint.

Add air supply

F-Link aggregates GDS, NDC, and LCC into one feed, with China-route coverage through Travelsky.

Integrate by Skills

Describe the integration in natural language; AI reads the docs and writes the code. API and SDK still supported.

Resolve errors fast

AI-assisted error resolution reads the request context and suggests a fix — most issues never need a human.

Ship your first integration.

Get sandbox access to G-Link and F-Link and run a real search-to-book flow without waiting for a long contract cycle.
