Stats API & CustomVariable

General questions
1

I have a rather specific question. I am calling the reports to get a JSON object using module UserId.getUsers, let’s say I wanted to also get a CustomVariable ‘Division’

Can I write this using a call similar to below or is another module needed to show it?

stats.myserver.com/piwik/?module=API&site=123&method=UserId.getUsers&period=day&date=2021-01-01,2021-02-09&expanded=true&format=json=token_auth=abc123

Response:
{“2020-02-09”:[{“label”:“Kevin”,“Division”: 'Analytics Department"}]}
