I have included the required files in the head as it says in the docs
<script src='https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js'></script>
<script src='https://cdn1.kongregate.com/javascripts/kongregate_api.js'></script>
And then right above my scripts i included the script that supposed to define the variable
<script>
kongregateAPI.loadAPI(function(){
window.kongregate = kongregateAPI.getAPI();
});
</script>
But in the console I am still getting this error
Uncaught ReferenceError: kongregate is not defined
