OAuth 2.0 isn’t easy, and everyone has a slightly different implementation, making interoperability a nightmare. Fortunately, the PHP League of Extraordinary Packages provides league/oauth2-client. Aiming for simplicity and ease-of-use, league/oauth2-client provides a common way to access providers. This talk introduces OAuth concepts and demonstrates how to perform OAuth flows with league/oauth2-client, using Instagram as an example.
