I am new to the elasticsearch and JavaScript development. I am trying to use the code below, so I can do regular REST calls and get JSON back.

Here is my code that I am using in section

function myFunction() {

var xhr = new XMLHttpRequest();  
xhr.open('GET', '[http://d77511xxx.us-central1.gcp.cloud.es.io:9243](http://d77511xxx.us-central1.gcp.cloud.es.io:9243)', true);  
xhr.withCredentials = true;  
xhr.setRequestHeader('Content-Type', 'application/json');  
xhr.setRequestHeader('Authorization', 'Basic ' + btoa('user:password'));  
xhr.send('{"query":{"match\_all":{}}}');  
}

Here is my additional setting that I am using in elasticsearch.yml

http.cors.enabled: true  
http.cors.allow-origin: "/.\*/"  
http.cors.allow-credentials: true  
http.cors.allow-headers: "X-Requested-With, Content-Type, Content-Length, Authorization"

But for some reason I am getting 401 or other issues.

Here is my ElasticSearch Server Link: [http://d77511xxx.us-central1.gcp.cloud.es.io:9243](http://d77511xxx.us-central1.gcp.cloud.es.io:9243)

Hi @danreut89

Note that I removed some chars from your cluster id (we recommend only including the first 6). Note also that we offer direct support for cloud - login and visit [https://cloud.elastic.co/help](https://cloud.elastic.co/help)

Very quickly though the first thing I noticed is that you have `http` but `9243` is an https port. So try `https://` instead.

401 is normally an bad user/password combo. Are you using the `elastic` and the password generated when you created the cluster (or when you reset it from the security tab)

eg Does the same call work from a `curl`, if you do

`curl -vv -u user:password 'https://d77511xxx.us-central1.gcp.cloud.es.io:9243' -d '{ "query": { "match_all": {} }' -H 'Content-Type: application/json'`

(with the correct user+password and the full cluster id)
