Git references

The Git references API lets you read and write references to your Git database on GitHub Enterprise Server

About the Git references API

A Git reference (git ref) is a file that contains a Git commit SHA-1 hash. When referring to a Git commit, you can use the Git reference, which is an easy-to-remember name, rather than the hash. The Git reference can be rewritten to point to a new commit. A branch is a Git reference that stores the new Git commit hash. These endpoints allow you to read and write references to your Git database on GitHub Enterprise Server.

List matching references

Works with GitHub Apps

Returns an array of references from your Git database that match the supplied name. The :ref in the URL must be formatted as heads/<branch name> for branches and tags/<tag name> for tags. If the :ref doesn't exist in the repository, but existing refs start with :ref, they will be returned as an array.

When you use this endpoint without providing a :ref, it will return an array of all the references from your Git database, including notes and stashes if they exist on the server. Anything in the namespace is returned, not just heads and tags.

Note: You need to explicitly request a pull request to trigger a test merge commit, which checks the mergeability of pull requests. For more information, see "Checking mergeability of pull requests".

If you request matching references for a branch named feature but the branch feature doesn't exist, the response can still include other matching head refs that start with the word feature, such as featureA and featureB.

Note: You need to explicitly request a pull request to trigger a test merge commit, which checks the mergeability of pull requests. For more information, see "Checking mergeability of pull requests".

Create a reference

Works with GitHub Apps

Creates a reference for your repository. You are unable to create new references for empty repositories, even if the commit SHA-1 hash used exists. Empty repositories are repositories without branches.

Parameters

Headers
Name, Type, Description
`accept`string Setting to `application/vnd.github.v3+json` is recommended.
Path parameters
Name, Type, Description
`owner`stringRequired The account owner of the repository. The name is not case sensitive.
`repo`stringRequired The name of the repository. The name is not case sensitive.
Body parameters
Name, Type, Description
`ref`stringRequired The name of the fully qualified reference (ie: `refs/heads/master`). If it doesn't start with 'refs' and have at least two slashes, it will be rejected.
`sha`stringRequired The SHA1 value for this reference.
`key`string
