    :arg module:   The AnsibleModule (used to get url, api_version, api_token, etc).
    :arg endpoint: The API endpoint to be used.
    :kwarg data:   The data to be sent (in case of POST/PUT).
    :kwarg method: "POST", "PUT", etc.

    :returns: A tuple of (**response**, **info**). Use ``response.read()`` to read the data.
        The **info** contains the 'status' and other meta data. When a HttpError (status >= 400)
        occurred then ``info['body']`` contains the error response data::
