I'm trying to use an API which returns me a JSON so I can use it on my function.
Imports
I'm importing Jquery, instafeed.min.js and the API (instant-tokens.com).

Instafeed script
<script type="text/javascript">
$(document).ready(function () {
var instantTokenApiUrl = 'https://ig.instant-tokens.com/users/133af082-bd46-416f-8d95-b6ca28a08bee/instagram/17841406882807948/token.js?userSecret=slqh9w7letquro8mj056yi'
$.ajax({
url: instantTokenApiUrl,
dataType: 'json',
})
.done(function (response) {
if (!response.Token) {
console.log('Error :: ', response);
} else {
var feed = new Instafeed({
accessToken: response.Token
});
feed.run();
}
});
});
</script>
I'm trying to do what's in this post: https://github.com/codingbadger/instant-tokens.com/wiki/3.-Instafeed.js-Demo
But my feed still isn't displaying, and it gives me these CORS errors:
Access to XMLHttpRequest at 'https://ig.instant-tokens.com/users/133af082-bd46-416f-8d95-b6ca28a08bee/instagram/17841406882807948/token.js?userSecret=slqh9w7letquro8mj056yi' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

My question is: Is there a workaround for this? I'm fairly new to ajax and JSON, so I hope people can tell me what I'm doing wrong.
Update
For some reason, it worked after I added the instafeed function manually to my code, instead of linking it from an external source.
And at the end, I'm making an ajax request.
