The Git Database API gives you access to read and write raw Git objects to your Git database on {% data variables.product.product_name %} and to list and update your references (branch heads and tags). For more information about using the Git Database API, see "[Getting started with the Git data API](/rest/guides/getting-started-with-the-git-database-api)."
