About apps
You can build integrations with the GitHub APIs to add flexibility and reduce friction in your own workflow. You can also share integrations with others on GitHub Marketplace.
Differences between GitHub Apps and OAuth Apps
Understanding the differences between GitHub Apps and OAuth Apps will help you decide which app you want to create. An OAuth App acts as a GitHub user, whereas a GitHub App uses its own identity when installed on an organization or on repositories within an organization.
Creating a GitHub App
You can create and register a GitHub App under your personal account or under any organization you have administrative access to.
About authentication with a GitHub App
Your GitHub App can authenticate as itself, as an app installation, or on behalf of a user.
