How can I retrieve the gps data (such as altitude and longitude)

[ust]

How can I retrieve it from the fitbit api? Is it possible?

See the Get Activity TCX endpoint.

Thanks for response. But how can I retrieve the log id by api without manually looking for the web log page?

[JeremiahFitbit]

Use the Get Activity Log List endpoint.

[ust]

https://api.fitbit.com/1/user/-/activities/list.json

in this endpoint it doesn't have a encoded user_id 

how to I let the system know I am getting the specific user_id log?

@ust Which oauth flow are you using? Because user_id is included in the token endpoint. Otherwise, you can get encodedId from the profile endpoint.

I can get the encoded user_id from the oauth, but the log api doesn't seems have a place to put the user_id to get the correspond user_id log
