asp.net oauth2 MVC

[diggy016]

startup.cs

services.AddOAuth(options => { options.AuthenticationScheme = "FitBit-AccessToken"; options.AuthorizationEndpoint = "https://www.fitbit.com/oauth2/authorize"; options.TokenEndpoint = "https://api.fitbit.com/oauth2/token"; options.SaveTokensAsClaims = true; options.CallbackPath = new PathString("/signing-fitbit-token/"); options.ClientId = "[MY ID STRIPPED OUT]"; options.ClientSecret = "[MY SECRET STRIPPED OUT]"; options.DisplayName = "FitBit"; options.Scope.Add("activity"); options.Scope.Add("heartrate"); options.Scope.Add("location"); options.Scope.Add("nutrition"); options.Scope.Add("profile"); options.Scope.Add("settings"); options.Scope.Add("sleep"); options.Scope.Add("social"); options.Scope.Add("weight"); options.AutomaticAuthenticate = true; });

FitbitController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Mvc;

namespace FitBit_Oauth.Controllers
{
[Route("[controller]/[action]")]
public class FitbitController : Controller
{
[HttpGet]
//[Get("Enterhere")]
[Headers("Authorization : Bearer")]//
public IActionResult Login()
{
return Challenge(new AuthenticationProperties() { RedirectUri = $"/" });
}
}
}

I have tried this to authenticate fitbit user and retrieve access token, but I am getting invalid redirect_uri.

Can anyone suggest here, how to implement it in asp.net core MVC?

Hi @diggy016,

Welcome to the forums!

This error usually occurs when the redirect_uri in your application code does not match the redirect_uri you have in your application settings at dev.fitbit.com. Could you ensure that the two values match and try again?

Hi John,

Thank you for the reply!

I have double check the URI and they are same.

Best Regards,
