Google drive get list of users for an ID using a Server API Key
<p>How do I elevate writes to a server API Key so that it can get all user's groups?</p>

<p>I get a 403 permissions error whenever I try it. Which makes me think I'm missing some step where I give the API Key admin rights. </p>

<p>I have navigated in the Google api console every which way and I cannot find a way to assign group directory list authority to a user. </p>

<p>Anyone know how to assign this ability to list a given Google apps user's groups? </p>
