Get list of all dashboards/cubes from REST API

I am trying to come up with an automated way to document which of our users and groups have access to which dashboards and cubes. Using the REST API, I was pulling a list of elasticubes using the /v1/elasticubes/getElasticubes endpoint and a list of dashboards using the /v1/dashboards endpoint. However, it looks like this is only pulling the dashboards/cubes for the current user (me).

Is there a way to pull a list of ALL dashboards and elasticubes regardless of user from the API, or will I need to do something where I loop through each user to accomplish this?
