Download the PHP package league/oauth2-client without Composer

On this page you can find all versions of the php package league/oauth2-client. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.


After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

The OAuth 2.0 login flow, seen commonly around the web in the form of "Connect with Facebook/Google/etc." buttons, is a common integration added to web applications, but it can be tricky and tedious to do right. To help, we've created the league/oauth2-client package, which provides a base for integrating with various OAuth 2.0 providers, without overburdening your application with the concerns of RFC 6749.

This OAuth 2.0 client library will work with any OAuth 2.0 provider that conforms to the OAuth 2.0 Authorization Framework. Out-of-the-box, we provide a GenericProvider class to connect to any service provider that uses Bearer tokens. See our basic usage guide for examples using GenericProvider.

Many service providers provide additional functionality above and beyond the OAuth 2.0 specification. For this reason, you may extend and wrap this library to support additional behavior. There are already many official and third-party provider clients available (e.g., Facebook, GitHub, Google, Instagram, LinkedIn, etc.). If your provider isn't in the list, feel free to add it.

This package is compliant with PSR-1, PSR-2, PSR-4, and PSR-7. If you notice compliance oversights, please send a patch via pull request. If you're interested in contributing to this library, please take a look at our contributing guidelines.


We support the following versions of PHP:

Provider Clients
