Can we write data in Fitbit?

[よしだ]

Hi there. 

I am yoshi. I am in IT company.

I am making original app to scale my weight and save it. 

Is this possible to write data to Fitbit app from my app using API.

I tried to find a way but there is no document. 
If you guys have any solution, please share me.

Maybe you need to call `WebAPI` via `Companion API`.

(fitbit devie → phone → the Internet → FitbitAPI)

(I'm also a beginner, so I'm sorry if I make a mistake....)

Thank you for your response.

I checked these rinks. I am also a beginner too.

I would like to conform one thing.

My goal is that, scaled my weight data in my original app writes on fitbit application.

Is this possible?

(scale my app the weight data) → (use API ) → (show my weight data in fitbit app)

I have known that the weight data show my app from fitbit.

If you have known , Could you please let me know.
