Notification via Browser

I tried to do the following:

- Open up a website with the browser on my desktop PC

- That website contains a javascript that tries to send a notification to my LaMetric Time using basic authentication (knowing the local IP and API key)

- The browser decides to send an OPTIONS request first because of CORS

- The browser declines the request, as:

"No 'Access-Control-Allow-Origin' header is present on the requested resource."

Any advice?

Thanks for the quick reply.

Well, I have this backoffice-webpage that displays all kinds of internal information for my client. This webpage handles all kinds of security and logic in order to know who sees what information. So this webpage would have been my prefered place to send notifications to the user's LaMetric Time.

All it would have to do is respond to a OPTIONS HTTP request with the response header

access-control-allow-origin: *


Dear Martin,

Thanks for reaching out to us.

Unfortunately, currently, LaMetric Time doesn't support this.

But in order we had better understanding could you please share with us the purpose of your case? It will be helpful for our further investigations.

Thanks in advance.
