module: api_info
author:
  - "Felix Fontein (@felixfontein)"
short_description: Retrieve information from API
version_added: 2.2.0
description:
  - Allows to retrieve information for a path using the API.
  - This can be used to backup a path to restore it with the M(community.routeros.api_modify) module.
  - Entries are normalized, dynamic and builtin entries are not returned. Use the I(handle_disabled) and
    I(hide_defaults) options to control normalization, the I(include_dynamic) and I(include_builtin) options to also return
    dynamic resp. builtin entries, and use I(unfiltered) to return all fields including counters.
  - B(Note) that this module is still heavily in development, and only supports B(some) paths.
    If you want to support new paths, or think you found problems with existing paths, please first
    L(create an issue in the community.routeros Issue Tracker,https://github.com/ansible-collections/community.routeros/issues/).
