GitHub Apps making server-to-server requests use the installation's minimum rate limit of 5,000 requests per hour. If an application is installed on an organization with more than 20 users, the application receives another 50 requests per hour for each user. Installations that have more than 20 repositories receive another 50 requests per hour for each repository. The maximum rate limit for an installation is 12,500 requests per hour.
GitHub Apps and OAuth Apps can also act on behalf of a user, making user-to-server requests after the user authorizes the app. For more information, see "Authorizing GitHub Apps" and "Authorizing OAuth Apps."
User-to-server requests from OAuth Apps are authenticated with an OAuth token. User-to-server requests from GitHub Apps are authenticated with either an OAuth token or an expiring user access token. For more information, see "Identifying and authorizing users for GitHub Apps" and "Authorizing OAuth Apps."
User-to-server requests are limited to 15,000 requests per hour and per authenticated user. All requests from OAuth applications authorized by a user or a personal access token owned by the user, and requests authenticated with any of the user's authentication credentials, share the same quota of 15,000 requests per hour for that user.
