requesting token for specific subset of data

[dataread400]

I just managed to get fitbitr working in RStudio. It helped to look here.

I am conducting a psychology study where I have participants wearing a Fitbit Charge 4 for 7 days and nights. I want to be able to extract their profile, heart rate, activity, sleep, and weight data, but not all the other stuff. Is there a way to tailor the authorization page to specify that, the way you can using Fitbit's own OAuth 2.0 Tutorial page? The Tutorial page generates code that I could cut-and-paste somewhere.

So, if I run the fitbitr token command and it leads me to the browser... can I email that link to my participant? I think this is currently set-up to help you access your own data, but I need a way to access participant data.

Let's say they authorize the token. How does fitbitr get that code?

Once I've got the code, I figure I can use fitbitr to extract the data. I do have my own Fitbit account, so I can try and do this...

Please advise, esp. is anyone has used fitbitr to access consenting participant data.

Thanks!
