# Parameters:
#   cursor - string - Used for pagination.  Send a cursor value to resume an existing list from the point at which you left off.  Get a cursor from an existing list via the X-Files-Cursor-Next header.
#   per_page - int64 - Number of records to show per page.  (Max: 10,000, 1,000 or less is recommended).
#   sort_by - object - If set, sort records by the specified field in either 'asc' or 'desc' direction (e.g. sort_by[last_login_at]=desc). Valid fields are `group_id`, `path`, `user_id` or `permission`.
#   filter - object - If set, return records where the specifiied field is equal to the supplied value. Valid fields are `group_id`, `user_id` or `path`.
#   filter_gt - object - If set, return records where the specifiied field is greater than the supplied value. Valid fields are `group_id`, `user_id` or `path`.
#   filter_gteq - object - If set, return records where the specifiied field is greater than or equal to the supplied value. Valid fields are `group_id`, `user_id` or `path`.
#   filter_like - object - If set, return records where the specifiied field is equal to the supplied value. Valid fields are `group_id`, `user_id` or `path`.
#   filter_lt - object - If set, return records where the specifiied field is less than the supplied value. Valid fields are `group_id`, `user_id` or `path`.
#   filter_lteq - object - If set, return records where the specifiied field is less than or equal to the supplied value. Valid fields are `group_id`, `user_id` or `path`.
#   path - string - DEPRECATED: Permission path.  If provided, will scope permissions to this path. Use `filter[path]` instead.
#   group_id - string - DEPRECATED: Group ID.  If provided, will scope permissions to this group. Use `filter[group_id]` instead.`
#   user_id - string - DEPRECATED: User ID.  If provided, will scope permissions to this user. Use `filter[user_id]` instead.`
#   include_groups - boolean - If searching by user or group, also include user's permissions that are inherited from its groups?
