API access to weight, body fat & calories from Garmin Connect

Hi everyone,

I'm working on a web app that automatically calculates calorie targets based on Garmin data (weight, body fat %, calorie expenditure). I already have access to Garmin Connect and I’m looking for a way to retrieve this data via an API.

  • Is there any way to retrieve weight & body fat % from Garmin Connect via an API?
  • Can I access daily calorie expenditure (e.g., from activity data or daily summary)?
  • Which API (Garmin Health, Connect IQ, another one?) would be best suited for this?

Thanks for any help! Blush
