What is the use of GitLab API?

The GitLab API allows developers to automate tasks, integrate GitLab with other tools, and extend its functionality. It provides programmatic access to projects, repositories, issues, CI/CD pipelines, and user data. GitLab offers REST, GraphQL, and SCIM APIs for different use cases, such as project management, workflow automation, reporting, and security enforcement. This improves efficiency, integration, and scalability in DevOps workflows.
