DESCRIPTION
Get a behind-the-scenes look at development on the GitHub API team. Developers and businesses rely on the stability and consistency of the GitHub API for critical tasks. Changes to the API could break production deployments (or continuous integration, authentication, etc.) for thousands of businesses. And yet, GitHub.com continues to evolve, improving existing features, and adding new ones. The GitHub API needs to evolve as well. We'll explore the design philosophies and techniques that we use to provide a reliable API, while continuing to ship improvements every day.
