Ship Rush Browser Plugin Question

We are using the browser plugin in our lightweight web app. When we call the plugin with the order id how do we sent authentication? Do we need a token? Or is it basic auth which we need to tokenize? I can't seem to find any docs on the browser plugin.

Below is what my dev has started with but it's not actually logging anything or getting a 200 with the get request.

(obviousuly I just pasted the relevant info)

$(?form?).submit(function (e) {
var myShipRushWebsite = ?https://my.shiprush.com/ship/shipbutton?;
var dev_token="***************?;
var shipping_access_token=??shipping_access_token=? + dev_token;
var order_id = $(?#search_id?).val();
var order_json = ?{Order:{OrderNum:? + order_id + ?}}?;
var shipment_url_param = shipping_access_token + ?&shipment=? + encodeURIComponent(order_json);

var webShippingUrl = myShipRushWebsite + shipment_url_param;
alert(webShippingUrl);
var results = $.get(webShippingUrl);
console.log(results);
});


Thanks for your time.
