Activity post problem

[jschrimshire]

I am trying to post walking but the actual values posted are different than the values passed. The documentation doesn't explain why this is. In the post parameters I am passing a distance=6, steps=10000, and durationMillis=7200000. What gets posted is: steps=8620, distance = 3.73 miles. Can someone please explain what is going on?

6km is 3.7miles

So I guess you're posting in metric units (if not specified I think the API guesses this from the language), but displaying in imperial?

The Fitbit Web API always assumes metric units. If you want to use other unit systems, check out the localization documentation.

Yeah unfortunately the documentation just tells you that you need to Accept-Header=en_Us but doesn't tell you how to do it or where to do it.

Headers are a part of every HTTP request. You should consult the documentation for the HTTP library you're using on how to add a header.
