Querying data remotely using New Relic API throwing "404 error"

Question

Im using the following AJAX request to send request to New Relic, however its always throws "404 Not Found" error.

Following is the code:

var client = new XMLHttpRequest();
client.open("GET", "https://insights-api.newrelic.com/v1/accounts/REMAINING.URL", true);
client.setRequestHeader("Accept", "application/json");
client.setRequestHeader("X-Query-Key", "QUERY.KEY");
client.send();

Answer 1

Since the origin of the XMLHttpRequest (XHR) or Ajax is different to the requested API's URL, Cross-origin resource sharing (CORS) prevents from accessing the API. Hence, this doesn't work. To implement this, the API will have to be requested by the back-end via .NET, JAVA, PHP, Python, etc. any server side technology and the result will have to be sent to the client Ajax calls.
