I am currently developing an application using the Fitbit Web API and have some questions regarding the uniqueness of the logId for sleep records. I have reviewed the API documentation, including the following page:
However, I could not find detailed information about the uniqueness of logId.
Does anyone know the answers to the following questions?
- Is the logId globally unique across all users?
- Is the logId unique only within each individual user’s data?
- If logId is unique per user, is it still unique across different dates for the same user?
I would appreciate any insights on this matter. Thank you!

Hi @kazu098
We do not duplicate the sleep log Ids. They are unique across all logs, all users and all dates.
