Authorizations

Authorization · string · header · required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Path Parameters

repo_name · string · required

Repository name. Names that contain / or any other character that is not safe in a URL path segment must be URL encoded so the value occupies a single path segment. For example pierre/example is sent as pierre%2Fexample. Plain names such as example can be sent as-is. The server URL-decodes the value before resolving the repository.
