Garmin Lifestyle Logging
“Garmin now has a way of recording daily tags from its app, and Venu 4 watch (other watches likely to support this in their next update). Given these devices are already integrated in our daily lives (e.g. evening report feature), this would be a very convenient way to report tags to Exist.”
I’ve looked at our API docs for Garmin and they don’t seem to make this data available to us.
