Calling joget JSON API from external website

Hi, I am calling joget JSON API from external website. After I click the button in my external page, I got this result {"activityId":"","processId":"1003_BPM_onlineinspection"} . I want to ask, why the activityId is empty? and how do I display the run process form after the API is triggered?

here is my javascript:

<script type="text/javascript">
			function UserAction(){
				var data = null;
				var xhr = new XMLHttpRequest();
				xhr.withCredentials = true;
				xhr.addEventListener("readystatechange", function () {
				  if (this.readyState == 4 && this.status == 200) {
				    document.getElementById("demo").innerHTML =
				    this.responseText;
				  }
				});
				xhr.open("POST", "http://localhost:8080/jw/web/json/workflow/process/start/BPM:8:onlineinspection?j_username=admin&j_password=admin");
				xhr.setRequestHeader("content-type", "application/javascript");
				xhr.setRequestHeader("cache-control", "no-cache");
				xhr.setRequestHeader("postman-token", "36eee796-48be-b719-bcbf-dbd467a1af42");
				xhr.send(data);
			}
</script>
