Many of the device sources that Validic supports also allow the user to connect other apps, that we refer to as 3rd party apps, to that source. In many cases this does not cause any problems and the data from that 3rd party app flows through the supported source to the Validic API.
Garmin, however, does have some exceptions. Below is a list of known 3rd party apps that are able to populate their virtual workouts to a user’s Garmin account, but that data is not supported by the Garmin API and therefore will not be passed through to the Validic API.
