Room OS Auth in xmlHTTPRequest

[stevenmoran]

does anyone have a method of providing auth credentials to a room kit pro  os 10.15.3 so that you don't get prompted with a username password request when trying to push a OBTP booking. I tried providing it in a request header with 'Authorization', 'Basic 64bitEnc' but no luck

xmlHttp.open('POST', url, true);
xmlHttp.setRequestHeader('Content-Type', mimeType);
xmlHttp.withCredentials = true;
xmlHttp.send(xml);

xmlHTTPRequest.open() seems to accept 'user' and 'password' parameters (rather than supplying an 'Authorization' header): https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/open ... did you happen to try that way?
The RoomOS API does use Basic Auth, so you're on the right track.  What's the symptom/error of the problem?
