No longer getting sleep data?

[Kevin_H]

As of 6/16/2021 my host stopped getting sleep data. We request sleep as follows:

REQ:Method: GET, RequestUri: 'https://api.fitbit.com/1/user/-/sleep/date/2021-03-03.json', Version: 1.1, Content: <null>, Headers:
{
Authorization: Bearer <REDACTED>
}

but the returned content is:

RSP: StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

The code for this area of our application hasn't been changed in years and was working fine up to 6/16/2021, although I'll be continuing to do isolated testing.

Hi @Kevin_H 

You're using a deprecated version of the Sleep API.   The current version is 1.2.   Please try this endpoint to see if the sleep data is returned.

Sorry, I couldn't find my original post to update after I found the answer.
This project is a research study that's just now going live. It's quite
common for researchers to "play the home game" basically acting as
subjects, but they tend to be super non-compliant. In past projects I found
that when they started participating again my Fitbit data retrieval code
would bog the system down, so I added a 2-weeks-at-a-time throttle.
Unfortunately sleep data will never fill in, so anyone with more than 2
weeks of no sleep data would never get past the throttle.

I was aware of the 1.2 mods, I may have copied the wrong request from the
log. The specs seem to suggest that original sleep data and 1.2 data can be
returned, so we record both for secondary analyses.

Thank you for your help, and please close this thread.

Hi @Kevin_H 

The devices store about 6-7 days of data.  I'd recommend reducing your throttle to maybe 4-5 days.
