NPrinting: How to call NPrinting API with javascript ?

• NPrinting Server April 2018 and later

var url  = "https://qlikserver1:4993/api/v1/tasks/35818c86-7f4e-4170-9684-6b1b7762f51b/executions";
var xhr  = new XMLHttpRequest()

xhr.open('POST', url, true)
xhr.setRequestHeader('Authorization','Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6Ikp......EUtP2eu8YDxBsvOJCwC9D0ercMrrV-6zDiwJ6ySVgfOMoEtY5gCrhRSuKLg');
xhr.onload = function () {
    var tasks = JSON.parse(xhr.responseText);
    if (xhr.readyState == 4 && xhr.status == "200") {
        console.table(tasks);
    } else {
        console.error(tasks);
    }
}

xhr.send(null);

If the header does not get send, check that the web server hosting the code is set up correctly to allow the headers sent (CORS issue)
