Reference for all Bookmarks (template variables) supported in Event action fields.
Bookmarks are template variables you can embed in text fields of Event actions. When an event fires, Ubidots replaces each bookmark with the actual value from the triggering context — the device, variable, and data point that caused the event to activate.
For example, {{variable.name}} was {{last_value}} becomes Temperature was 35.2 at the moment the event fires.
