Yeah that’s outdated. Thanks for pointing it out. We’ll get that fixed.
The code with the listener and callback is what I’m referring to.
The first endpoint allows you to send a message to one or more devices at a time using your API key or username and password as credentials and to any port on the devices.
The second one doesn’t require any extra credentials and has a port locked in, but only works on a single device at a time.
Both of those should work to send a message to the Dash.
