Fitbit API with AFOAUATH2Manager Failing

[iosDev]

Hi everyone ..

This is my first interaction with fitbit auth and awful exp. my app written in Obj-c , there are not enough tutorial or example .. however i got this link to use http://stackoverflow.com/questions/36915238/get-authorization-from-fitbit-using-oauth-in-ios

but always getting stuck with error invalid_client , when i use same auth code at  hurl.it it works but not in app , will be great help if someone guide me 

Thanks Alot

@iosDev What's the specific error? Invalid_client is just the error type.

First of all thank you for your response , it really too fast 🙂

always it fails with error 400 or if i successfully remove 400 then 401 , and in response i received some NSData , after serializing it error type invalid client blah blah ....

do i'm using right steps ?? 

like link i posted says i will get auth auto , but i need to fillter callbackurl to get auth is it right ??

here is error

@iosDev Looks like you're using an access token where you should be using an authorization code. See Access Token Request.

If you want to refresh an expired access token, then you need to use the refresh token.
