Pushover formatting error

Total newbie trying to get Pushover to work for system alerts.

The error message is not sufficiently specific to be helpful to me.

Can someone see and tell me what “is not properly formatted”?

Thanks in advance!

What automation are you using to send this notification? Can you please share a screenshot? For example, if using RM to send the notification, please share a screenshot of the specific Rule.

Also, can you just open the Pushover device and send a notification successfully?

Have you followed the directions to set up the Pushover device with your Pushover credentials/keys?

In the Preferences for the Pushover Virtual device you created you put in the API key and User key? At the top of that device you can put a test message in the Device Notification text field and click the Device Notification button to send a test message. If that doesn't work you need to look at the Preferences to make sure you got those all set correctly.
