Service Catalog Get logged in user's account

I am currently trying to get the logged in user's account using this Field and Form rule script:

var user_id = $CS.getLoggedInUserId();

jQuery.ajax({

type: 'GET',

url: './sdpapi/admin/requester/' + user_id,

cache: false,

data: {'format':'json'},

success: function(user_data){

console.log("Account: " + user_data.operation.details[0].account);

error: function(response){

throw response.responseText;

}

});

However, this will only work on technician side. If I want this to work on the requester side, it'll require me to expose a TECHNICIAN_KEY which will be a security risk. I need this to run some rules depending on the logged in user's account.

Is there any other method that I can use?
