Login check fitbit versa 3

[katerina00988]

Hello,

I'm having issues of how to check if I am login in fitbit. I mean i want to check if I am login when i select for example my profile data which i take from companion. If am I not, then see an error message that i need to login. I cannot understand which variable should i take to make the if statement. Have anyone any idea?

There's an example here of setting up oauth authentication to use the Web APIs from the companion. https://github.com/Fitbit/sdk-oauth
