Can request SpO2 but not HRV and breathing rate

[KULKver]

I am using the Fitbit API for Python (by Orcas). Recently, breathing rate, SpO2 and HRV have been added to the Web API but I am only able to request SpO2. I have added respiratory_rate and oxygen_saturation to the scope of my session and the Fitbit device is a Charge 4. The following url request for SpO2 gets returned successfully with a JSON:

https://api.fitbit.com/1/user/-/spo2/date/2021-10-20/2022-06-22.json

However, if I do the same for breathing rate and HRV as in the following requests hereunder, I receive a 404 Not Found exception. I'm not able to find any explanation since the url has the same structure as on the official Web API examples. I would be very grateful for a solution! 😁

Hi @KULKver 

The new interval endpoints only support a date range of 30 days.   See https://dev.fitbit.com/build/reference/web-api/breathing-rate/get-br-summary-by-interval/.   Please reduce your interval period and let me know if that works.
