Fitbit Authentication Error: "Sorry, the page is following a different trail"

[sunil_openxcell]

Hello,

Currently I'm integrating Fitbit API in iOS. During authentication getting error page "Sorry, the page is following a different trail" [Error Page Link] when call authorize api "https://www.fitbit.com/oauth2/authorize". I follow all instruction as mentioned on fitbit oauth page. I created app on dev.fitbit.com and setup Demo accordingly.

Also I searched this error but not able to find relatable solution.

Here is mentioned details which I used for,

Platform: iOS

Swift: 5

OAuth2.0 Library: OAuthSwift 

AuthorizeUrl: "https://www.fitbit.com/oauth2/authorize"

AccessTokenUrl: "https://api.fitbit.com/oauth2/token"

Simulator: Error Page Link

Followed all steps properly and let me know if any other details required from my side.

Hi @sunil_openxcell 

Just to confirm, when calling the authorize API are you seeing the scopes or fitbit login page, or are you receiving the error message?
