Authentication issue

[squirrelB]

Hi, I've tried using both teramonagi/fitbitr and Avsecz/fitbitr, and both times I'm getting an error message:
"The app you're trying to connect did not provide valid information to Fitbit. Please report this issue to them.
Developer information: invalid_request - Invalid redirect_uri parameter value"
Not sure why. Callback URL is http://localhost:1410, "read-only" access type. Have tried going to the www.fitbit/oauth2/authorize... and allowed and got message "Authentication complete. Please close this page and return to R." Can't figure out what I'm doing wrong and how to fix.

Hey @squirrelB ,
the problem was in R's httr library - it always append a slash (/, %2F in the url code) to the redirect_uri:

https://www.fitbit.com/oauth2/authorize?client_id=....&redirect_uri=http%3A%2F%2Flocalhost%3A1410%2F&response_type...

In order to make it work, you have to put a slash to your app configuration as well:

I'll update the README.md
