Marking mandatory fields

[ritu.jain]

Hi Fitbit Team,

I was trying to capture data from the fitbit device but at times few attributes do not come in the response message, for eg. with API call, https://api.fitbit.com/1/user/<user-id>/activities/heart/date/today/1d.json, the restingheartrate is not coming up at times. 

So I wanted to know if there's a place where I can find all the mandatory attributes which will always come in the response irrespective of any deviations in the dependencies? If so, please help me know. (Something like a DTD for an XML, anything for the JSON)?

Regards,

Ritu.

If resting heart rate is not returned, no value is available for that day.

Does this mean, any parameter which is not captured can be skipped altogether from the response message? How can I make sure that the parameters do not get skipped?

Do we have a list of mandatory parameters, which will appear in the message irrespective of anything.

@ritu.jain Not necessarily; you could have 0 steps for the day and it will still show up as:

"steps": 0,

@ritu.jain Check for them in the response.

@ritu.jain No, but the example responses in the docs should give you a pretty good idea of what to expect.
