Puntos de conexión de la API de REST para referencias de Git

Acerca de las referencias de Git

Una referencia de Git (git ref) es un archivo que contiene un hash SHA-1 de una confirmación de Git. Al hacer referencia a una confirmación de Git, puede usar la referencia de Git, que es un nombre fácil de recordar, en lugar del hash. La referencia de Git se puede reescribir para apuntar a una confirmación nueva. Una rama es una referencia de Git que almacena el hash de la nueva confirmación de Git. Estos puntos de conexión permiten leer y escribir referencias en la base de datos de Git en GitHub.

List matching references

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.

Get a reference

Returns a single reference from your Git database. 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 match an existing ref, a 404 is returned.

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".
