Looking at the API bindings:

class RepositoriesApi(object):

    def repositories_versions_create(self, href, data, **kwargs):  # noqa: E501
        """repositories_versions_create  # noqa: E501

        :param str href: A relative URI for the resource. (required)
        :param RepositoryVersion data: (required)
        :return: AsnycOperationResponse
                 If the method is called asynchronously,
                 returns the request thread.
        """
        pass

    def repositories_versions_delete(self, href, **kwargs):  # noqa: E501                               
        """repositories_versions_delete  # noqa: E501                                                   

        :param int href: A relative URI for the resource. (required)                                    
        :return: AsnycOperationResponse
                 If the method is called asynchronously,
                 returns the request thread.
        """

It's not totally clear what href means. Also, for repositories_versions_delete() it says the href type is an int.
