Git blobs

Use the REST API to interact with a Git blob (binary large object), the object type used to store the contents of each file in a repository.

About 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 Server. Blobs leverage these custom media types. You can read more about the use of media types in the API here.
