'BAD REQUEST' When calling API using Fetch method in JavaScript

I'm trying to return some data from an API using the Fetch method, but I'm getting a 400 error. I'm probably missing something obvious, but I've been at this for so long I probably can't see the wood for the trees.

<script type="text/javascript">

function getJSON() {

    const API = 'https://API-URL-ENDPOINT';

    const QUERY = 'sample-query';

    const A_KEY = '{API Key}';

    const A_SEC = '{API Secret}';



    let headers = new Headers();

    headers.append('Authorization', 'Basic ' + USERNAME + ":" + PASSWORD);



    {/* Fetch Method Here */}

      fetch(API, {method: 'GET', headers: headers })

      .then(response => response.json())

      .then(json => console.log(json));

      }



      function parseJSON(response) {

          return response.json()

          }

</script>

If anyone can offer any hints, that would be great.

As written in the docs for the Authorization header, you need to encode it in base64.

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Authorization

So try headers.append('Authorization', 'Basic ' + btoa( USERNAME + ":" + PASSWORD ));

Thanks, fixed. Typos can even sneak into Basic questions if you're in a hurry. ;)
