Role remove API call

https://community/vc/roles/name/Analytics/users/remove?role.user=id/1286

I've checked the user I'm logged in as as have permission to add/remove roles, but when I copy/paste this into the brower nav bar the action is not performed. 

Background

We are apply a role to new users to restrict from adding a signature/DM without first acheiving a high role of activity (to cut down on spam). The mod team wants the ability to remove the role on a case by case basis. The role of the mod team does allow read/write of API calls. 

Ask

I would like the mod team to be able on a case by case basis locate the Id of the impacted users and remove the role through the browser using this call. 

What other settings am I missing to now allow this call to complete in my testing? Is there an extensionon Chrome/Firefox I should be using to make POST calls? 

Appreciate the clarification.
