title: How to list a subgroup's projects using the GitLab API?
body: <p>In GitLab you can create subgroups within a group and projects within those subgroups. The GitLab documentation allows you to list the subgroups of a group and the projects of a group, but I cannot find anything about listing projects of a subgroup. Does anyone know the curl command for this, or at least know that it's not supported yet?</p>
  
  <p>I've tried:<br>
  <code>curl -s -H 'PRIVATE-TOKEN: xxxxx' https://gitlab.com/api/v4/groups/mygroup/subgroups/mysubgroup/projects</code><br>
  <code>curl -s -H 'PRIVATE-TOKEN: xxxxx' https://gitlab.com/api/v4/subgroups/mysubgroup/projects</code><br>
  and other similar variations with no luck so far.</p>
