Call API on button click

[YZsoft]

Hi,

i’d like to have a button to call an API. I just need to call an URL, not to open it.
I used action Open URL, the URL is called but it opens a new tab in my navigator, that’s not what I want.
I tried to use a function to make a HTTP request, but nothing happens (i don’t the URL call on the server).
This is the code I used with the execute action :

function request() {
    var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function() {
        if (xhr.readyState === XMLHttpRequest.HEADERS_RECEIVED) {
            print('HEADERS_RECEIVED');
        } else if(xhr.readyState === XMLHttpRequest.DONE) {
            print('DONE');
        }
    }
    xhr.open("GET", "http://example.com");
    xhr.send();
}
(from documentation)

Thanks for your help.

Best regards

YZ
