Can you help with my OB config?

[strydez]

I'm trying to get into fitbit but I'm getting this response from the API

{"errors":[{"errorType":"invalid_grant","message":"Invalid username/password. Visit

You do not have permission to view the link please Log in or Register

for more information on the Fitbit Web API authorization process."}],"success":false}

I've checked the logins and ensured that it was right ( I tested it on the site ) but no luck still in trying to get past this

This is my request block loli code
