Introduction

liteAPI is an innovative and robust collection of infrastructure APIs that cater to the travel industry. It is designed to empower developers, offering them the fastest way to build and launch comprehensive travel applications.

At the heart of LiteAPI's power is its extensive network of over 2 million properties worldwide. By incorporating LiteAPI into an app, developers can effortlessly tap into the vast inventory, allowing users to search and book accommodations at these properties.

But that's not all. With LiteAPI, monetization is made even more simple. Developers can generate revenue through their hospitality products by selling accommodations from LiteAPI's broad portfolio of properties. This means that not only can developers launch their products quickly, they can also start generating profits in no time.

LiteAPI opens up a range of powerful functions for travel and hospitality applications. Its features include:

Hotel Search:

Developers can incorporate a robust search function that allows users to find hotels based on their preferred destination. This can help users discover accommodations that suit their travel plans.

Static Content for Hotels:

LiteAPI also provides access to static content for hotels, including descriptions, images, and amenity details. This is essential for developers to present comprehensive and accurate information to the end users, aiding their decision-making process.

Room Rates & Availability:

One of the most significant features of LiteAPI is the ability to pull data on room rates and availability for a selected set of hotels. This feature ensures users have real-time, accurate information to assist in their booking decisions.

Hotel Booking:

Beyond just providing information, LiteAPI also allows developers to integrate a seamless booking function. Users can select a specific hotel with room availability and proceed to make a booking directly within the app.

Booking Management:

With LiteAPI, managing bookings becomes a straightforward task. The booking management functions allow for the tracking and management of all bookings made through the app, ensuring users can keep track of their travel plans.

Booking Retrieval and Cancellation:

Lastly, LiteAPI offers the capability to retrieve and cancel existing bookings. This added flexibility is crucial for users who might need to alter their travel plans.

All these features make LiteAPI a comprehensive solution for travel app development, offering a plethora of functionalities, from search and booking to management and cancellation. Developers can harness these powerful tools to create high-quality, user-friendly travel applications.

Installing

Make sure your project is using Go Modules (it will have a go.mod file in its root if it already is):

go mod init

Run any of the normal go commands (build/install/test). The Go toolchain will resolve and fetch the liteapi-travel/go-sdk module automatically.

Alternatively, you can also explicitly go get the package into a project:

    go get -u github.com/liteapi-travel/go-sdk/v2

Then, reference liteapi in a Go program with import:

import (
	liteapi "github.com/liteapi-travel/go-sdk/v2"
)

Usage

After you have installed the LiteAPI package, you need to configure it with your API key. The API key is available in the liteAPI Dashboard. Here's the step to add the API key to the package.

	configuration := liteapi.NewConfiguration()
	configuration.AddDefaultHeader("X-API-KEY", "YOUR_API_KEY")
	apiClient := liteapi.NewAPIClient(configuration)

Static data

Static data can be directly fetched from the functions below. Alternatively, LiteAPI also provides an option to download static data directly from the Github URL.
