Asp net webapi identity facebook login access denied


ASP.NET is a popular programming language used for building web applications. It provides a framework for websites and web services. One of the key features of ASP.NET is its to handle user authentication and authorization. In this article, we will explore how to implement Facebook login using ASP.NET Web API Identity and troubleshoot the “access denied” issue that may arise during the process.

up ASP.NET Web API Identity

Before we dive into implementing Facebook login, let's first set up ASP.NET Web API Identity. This will provide us with the necessary infrastructure for managing user authentication and authorization in our application.

Implementing Facebook Login

To implement Facebook login in our ASP.NET application, we need to follow these steps:

Step 1: Create a Facebook Developer Account

First, we need to create a Facebook Developer account and set up a new application. This will provide us with the necessary and to integrate Facebook login into our ASP.NET application.

Step 2: Install the Facebook SDK

Next, we need to install the Facebook SDK for .NET. This SDK provides us with the tools and libraries to interact with the Facebook API and authenticate users using their Facebook credentials.

Step 3: Configure Facebook Authentication in ASP.NET

Once the SDK is installed, we need to configure Facebook authentication in our ASP.NET application. This involves providing the Facebook app ID and app secret obtained from the Facebook Developer account.

Step 4: Implement Facebook Login Endpoint

Now, we can implement the Facebook login endpoint in our ASP.NET Web API. This endpoint will handle the authentication process and return the necessary access tokens and user information.

Troubleshooting “Access Denied” Issue

During the implementation of Facebook login, you may encounter an “access denied” issue. This can happen due to reasons, such as incorrect configuration or missing .

To troubleshoot this issue, you can follow these steps:

Step 1: Verify Facebook App Settings

Double-check the Facebook app settings in your Facebook Developer account. Ensure that the app ID and app secret are configured and match the values used in your ASP.NET application.

Step 2: Check Redirect URLs

Make sure that the redirect URLs specified in your Facebook app settings match the URLs used in your ASP.NET application. Any mismatch in the URLs can result in an “access denied” error.

Step 3: Review Facebook Permissions

Check the required permissions for your Facebook login implementation. Ensure that your Facebook app has the necessary permissions to access the user's profile information and authenticate them.

Step 4: Debugging and Logging

Use debugging and logging techniques to identify any errors or exceptions that may be causing the “access denied” issue. Review the logs and error messages to pinpoint the root cause of the problem.


Implementing Facebook login in ASP.NET Web API Identity can enhance the user experience and provide a seamless authentication process. By following the steps outlined in this article and troubleshooting any “access denied” issues, you can successfully integrate Facebook login into your ASP.NET application.
