HRV Summary end point

[MattWebDev]

https://dev.fitbit.com/build/reference/web-api/heartrate-variability/get-hrv-summary-by-date/
I'm calling the HRV summary endpoint documented above but retrieve no data back.
Browsing here I'm seeing some say that HRV data isn't available via the Web API . If this is the case why is there a documented endpoint?
I'm looking to use these values as a part of scoring  fatigue/stress/readiness.
If this data is currently unavailable will become available later down the line?

Hi @MattWebDev,

Welcome to the forums!

The HRV endpoints are publicly available now on "Server" and "Client" application types. However, we've identified an issue with the "Personal" application setting for querying intraday data from the new endpoints (SpO2, HRV, and Breathing Rate), which is preventing the data from being accessed on this application type.

We're working with engineering to resolve this as soon as possible. In the meantime, you can use the Web API Explorer to pull the data from your account. For instructions on how to use the Web API Explorer, please refer to our documentation.

Let me know if you have any questions!

Hi JohnFitbit,

Cheers for your reply , I'm using a "Server" Application Type to call the HRV endpoints. I'm not calling the intraday endpoints only the summary. I don't receive any errors or messages  in the response just an empty array. 

Any advice welcome

@MattWebDev Do you have a sleep stage log recorded for the night of sleep you're querying? HRV is recorded only during sleep, and if you have a sleep stage log, theres a good chance you'll also have HRV data as well. It also takes about 15 minutes after a sleep log for HRV data to process, did you attempt to fetch the data before it was processed? Also, do you have an HRV supported device paired to your Fitbit account?
