Problem with GET /roles

I’m testing the GET /roles and i’m getting this response:

"success": false,
"error": "You do not have permissions to do this.",
"error_info": "Please check for more information about Pipedrive API.",
"data": null,
"additional_data": null

How do i get the permission to see all the list of roles?

Are you using an Admin API token when requesting these Roles?
