CORS Policy

Anyone know how to do an API get request from the iparams page?  I keep getting this error when trying to pull in the groups to a dropdown for mapping between two systems.

Access to XMLHttpRequest at '' from origin '' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Yes, i have added this to my headers.  It works from everywhere but the app.

This the code I am currently using:


dataType: "json",

type: "Get",

beforeSend: function(request) {

request.withCredentials = true;

request.setRequestHeader("Authorization", "Basic " + btoa($("#fs_api_key").val() + ":X"));

request.setRequestHeader("Access-Control-Allow-Origin", "*");

request.setRequestHeader('X-Requested-With', 'XMLHttpRequest');


url: "https://" + $("#fs_subdomain").val() + "",

success: function(data) {

results = JSON.stringify(data.ticket_fields);

groups = getProperty(results, "group", "choices");


var select = $(dropdown).empty();

$.each(groups, function(key, value) {

select.append('<option value="'+ value +'">'+ key +'</option>');
