weight.update for historical weight data

[Andrew L]

Hi,

I've been wanting to move my weigh in data to fatsecret.  I have an export of historical weight from a previous tool (fitbit) and wrote a python script to update it, however it seems the weight.update method is limited to within 2 days of the current date.

Is there another way to load historical weight data into the app via the API?

    params = {

        'method': 'weight.update',

        'current_weight_kg': weight_kg,

        'date': date_int,

        'format': 'json'

    }

But I get the following:
Error for 2026-02-20: Date must be within 2 days from today: please check your date (current date 20508)
Error for 2026-02-19: Date must be within 2 days from today: please check your date (current date 20508)
Error for 2026-02-18: Date must be within 2 days from today: please check your date (current date 20508)
Error for 2026-02-17: Date must be within 2 days from today: please check your date (current date 20508)
Error for 2026-02-16: Date must be within 2 days from today: please check your date (current date 20508)

Thanks in advance!

Hi Andrew,

Thanks for reaching out. There is currently no other facility or way of importing historic weight data for a fatsecret user account
