GitHub REST API

The GitHub REST API enables programmatic control over repositories, issues, and pull requests via standard HTTP methods and JSON payloads.

Engineers use this interface to automate workflows across the entire SDLC. It provides granular access to over 300 endpoints, including the Repositories API for file management and the Actions API for CI/CD orchestration. By leveraging OAuth2 tokens and rate limits (5,000 requests per hour for authenticated users), teams build custom integrations that sync Jira tickets, trigger deployments, or audit organization-level security logs. The API follows REST constraints strictly: use GET to fetch commit history, POST to open a new issue, and PATCH to update a pull request status.
