I have a server based application that will cycle through registered users to do fitbit team competitions. The refresh token call is failing with a 400. Here is the problem. I authorize the user. If i wait a few minutes and call the refresh token, i get the error shown below. I am positive that the authorization has not been revoked. Any help is appreciated as this is stopping me from going live with my application.
{"errors":[{"errorType":"invalid_grant","message":"Refresh token invalid: REMOVED TOKEN FOR EMAIL. Visit https://dev.fitbit.com/docs/oauth2 for more information on the Fitbit Web API authorization process."}],"success":false}
