Hi @Faridh
Here is the documentation on querying the Sleep Log using the Web APIs, https://dev.fitbit.com/build/reference/web-api/sleep/. It doesn't look like our logs state if the entry was manual. But, if you see only 1 piece of data in the levels section (meaning sleep stages or patterns does not exist), then you can assume the sleep log was manually entered.
