access to heart rate raw data

[LisaSimon]

Hello everyone,

I'm a master degree student at Haifa University. 

I'm interested in using Fitbit bracelets (Alta HR) in my research in order to monitor heart rate variability every hour during 5/7 days of real-life activity. 

I was wondering what kind of raw data of heart rate can I extract from the user's data? and in what way? Is there any external app I can use in order to have access to this kind of data?

I discussed this topic with Fitbit customer services and they told me that there is no access to the heart rate raw data and I should ask in this forum.

Best Regards,

Lisa Simon

I just implemented the WebApi for a client and heart rate data is accessible. It appears though you aren't looking to develop something but looking for a system that provides this data to you? There is an excellent working examples created by Aaron Coleman(https://github.com/aarondcoleman/Fitbit.NET). Check out the description of the Api at: https://dev.fitbit.com/build/reference/web-api/heart-rate/ 

Hope this helps

Thank you, @MurfRocks.  I'd like to add that the Web APIs will return the pre-defined heart rate zones and custom heart rate zones, how much time a person has been in each zone, your resting heart rate, and the heart rate can return your heart beat over a date/time range based on the detail-level specified in the API call.  You can use the Web API Explorer Tool, https://dev.fitbit.com/reference/web-api/explore/, to test the Web APIs and see what output is generated.

@Gordon-C how can I access historical data from Fitbit web api for HeartRate? 

I have a Fitbit Flex2 which does not detect HeartRate, can you please share sample response, so that I can get an idea how data from the device would look like.

Thanks in advance 🙂

Hi @ayush-tr,

Have you checked out the Heart Rate APIs?  The link to the documentation is https://dev.fitbit.com/build/reference/web-api/heart-rate/.  You can reference a specific date or date range.  The documentation provides some sample outputs.  Also, the Web Explorer, https://dev.fitbit.com/reference/web-api/explore/, is a good tool for providing sample output.  The heart rate endpoints in the Web Explorer can be found under "Time Series".

Let me know if this doesn't provide you the information you need.
