Pontos de extremidade da API REST para referências Git

Sobre referências do Git

Uma referência do Git (git ref) é um arquivo que contém um hash SHA-1 de commit do Git. Ao referir-se a um commit do Git, você pode usar a referência do Git, que é um nome fácil de lembrar, em vez do hash. A referência do Git pode ser reescrita para apontar para um novo commit. Um branch é uma referência do Git que armazena o novo hash de commit do Git. Esses pontos de extremidade permitem que você leia e escreva referências ao seu banco de dados Git em 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".
