I am currently developing a health platform that utilizes the Garmin Developer APIs to access athlete activity and wellness data. I have successfully implemented the following API endpoints:
apis.garmin.com/.../userMetrics
apis.garmin.com/.../activities
I have observed that I can successfully retrieve data for approximately 18 days(or probably the current month, if start from today i got the data till 30th march 2025). However, when attempting to fetch older data (up to 180 days), the API returns a 200 status code but with no data in the response.
what am i missing here?
