Extracting the code for an Oauth 2 Call


I have successfully created a post call to pickup a token.

When I click the code snippet and put it my code, I am getting a

Access to XMLHttpRequest at ‘Https://test.company/auth/token’ from origin test’ 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.

The javascript code snippet generated does not contain all things neccessary.
var settings = {
“async”: true,
“crossDomain”: true,
“url”: “https://testcompany.com/API/Auth/Token”,
“method”: “POST”,
“headers”: {

“data”: {
“grant_type”: “client_credentials”,
“client_id”: " 12345-abcdeftest",
“client_secret”: “2345-abcdefgh”

$.ajax(settings).done(function (response) {
