Git Blobs

A Git blob (binary large object) is the object type used to store the contents of each file in a repository. The file's SHA-1 hash is computed and stored in the blob object. These endpoints allow you to read and write blob objects to your Git database on GitHub Enterprise. See the Git Database API for more details. Blobs leverage these custom media types. You can read more about the use of media types in the API here.

Note: To help with migrating from our REST API v3 to GraphQL API v4, we're introducing a preview period to include the GraphQL node_id in the response for many REST API v3 resources. See the blog post for full details. To access node_id during the preview period, you must provide a custom media type in the Accept header:

application/vnd.github.jean-grey-preview+json

Warning: The API may change without advance notice during the preview period. Preview features are not supported for production use. If you experience any issues, contact GitHub Enterprise Support.
