Bitly SDKs & Libraries: Official and Community Integrations (2026)

SDKs overview

Bitly offers a developer API that allows programmatic access to its core services, including URL shortening, custom branded links, and QR code generation. While Bitly maintains a focus on direct API interaction through its comprehensive Bitly API reference documentation, a selection of official and community-contcontributed Software Development Kits (SDKs) and libraries are available to streamline integration. These SDKs typically handle the complexities of HTTP requests, JSON parsing, and OAuth 2.0 authentication, allowing developers to focus on application logic rather than low-level API communication. The Bitly developer experience emphasizes clear documentation and a playground for testing API calls.

Integrating with Bitly's API through an SDK can accelerate development by providing idiomatic language constructs for common operations like creating a short link or retrieving link analytics. OAuth 2.0 is the standard authentication method, ensuring secure access to user data and API functionality. Developers can obtain an access token by following the Bitly authentication guide, which is then used to authorize API requests made through an SDK or direct HTTP calls.

Official SDKs by language

Bitly provides official SDKs for specific programming languages to facilitate integration. These SDKs are maintained by Bitly and are designed to offer robust, up-to-date functionality that aligns with the latest API versions. They typically include methods for all major API endpoints, error handling, and support for OAuth 2.0 authentication. The official SDKs are the recommended approach for new integrations due to their reliability and direct support from Bitly's development team. Developers can find detailed information and usage examples within the Bitly developer documentation.

The following table outlines the officially supported SDKs:

Installation

Installing a Bitly SDK typically involves using the package manager specific to your programming language. These commands fetch the necessary library files and their dependencies, making them available for use in your project. Ensure you have the respective package manager installed and configured in your development environment.

Python

To install the official Python SDK, use pip:

pip install python-bitly-api

This command downloads the python-bitly-api package from the Python Package Index (PyPI) and installs it into your Python environment. You can then import it into your Python scripts using import bitly_api.

Node.js

For Node.js projects, use npm or yarn to install the bitly package:

npm install bitly
# or
yarn add bitly

This adds the Bitly library to your node_modules directory and updates your package.json file. You can then require it in your JavaScript files: const BitlyClient = require('bitly');.

PHP

PHP developers can install the Bitly API client using Composer:

composer require bitly/bitly-api

This command adds the bitly/bitly-api package to your project's vendor directory and registers it in Composer's autoloader. You will need to include Composer's autoloader in your PHP script: require 'vendor/autoload.php';.

Quickstart example

This quickstart example demonstrates how to use the official Node.js SDK to shorten a URL. Before running this code, ensure you have installed the Node.js SDK and obtained an OAuth 2.0 access token from Bitly. Replace YOUR_BITLY_ACCESS_TOKEN with your actual token.

const { BitlyClient } = require('bitly');

const bitly = new BitlyClient('YOUR_BITLY_ACCESS_TOKEN');

async function shortenUrl() {
  try {
    const longUrl = 'https://www.example.com/very/long/url/that/needs/to/be/shortened';
    const response = await bitly.shorten(longUrl);
    console.log('Shortened URL:', response.link);
  } catch (error) {
    console.error('Error shortening URL:', error);
  }
}

shortenUrl();

This example initializes the Bitly client with your access token and then calls the shorten method with the long URL. The response object contains the shortened link, which is then printed to the console. Error handling is included to catch potential issues during the API call, such as invalid tokens or network errors. For more detailed examples and available methods, consult the Bitly API reference documentation.

Community libraries

Beyond the officially supported SDKs, the developer community has created and maintained various libraries for integrating with the Bitly API across different programming languages and frameworks. These community-driven projects can offer alternatives for languages not officially supported or provide additional features and abstractions tailored to specific use cases. While not directly supported by Bitly, many are actively maintained and widely used. Developers should evaluate the maturity, documentation, and community support of these libraries before integrating them into production systems.

Notable community-contributed libraries include:

• Ruby: Several Ruby gems are available, such as bitly-rb, which provides an object-oriented interface to the Bitly API. These libraries often leverage Ruby's metaprogramming capabilities to create a clean and expressive API client.
• Java: While not an official SDK, several open-source Java clients exist on platforms like GitHub, offering methods to interact with Bitly's endpoints. Developers frequently use general-purpose HTTP clients like Apache HttpClient or OkHttp alongside JSON parsing libraries to build their own Bitly integrations in Java, as detailed in various HTTP status code documentation.
• Go: Go language users often rely on direct HTTP request libraries combined with JSON marshaling/unmarshaling to interact with RESTful APIs. Community libraries for Bitly in Go typically wrap these functionalities into a more convenient package, providing Go-idiomatic structs and functions for API calls.
• C#/.NET: Developers in the .NET ecosystem can find community-maintained NuGet packages that encapsulate Bitly API calls. These libraries often integrate with .NET's asynchronous programming model and provide strong typing for API request and response objects.

When choosing a community library, it is advisable to check its last update date, the number of contributors, and its issue tracker to gauge its ongoing support and compatibility with the latest Bitly API version. The Bitly developer portal remains the authoritative source for API specifications, which should be cross-referenced with any third-party library's implementation.
