December 24, 2019 (Updated as per latest Facebook Developer Portal)

This blog post was originally written in December 2017. Facebook has changed it's developer portal user interfaces since then. We updated this blog post and included the steps as per latest developer portal steps.

If you ever need to integrate Facebook Login or use Facebook graph API, you can hire asp.net developers from us at affordable rate.

To use the Facebook API, like the Login with Facebook or Facebook Graph API, you need to create a Facebook App. When you make a Facebook App, that app will have an App ID and an App Secret. You need these credentials to do almost anything with Facebook, including going through the OAuth authorization flow and working with Facebook's Graph API.

With the App ID, you can send API requests to Facebook for data. The Facebook App Secret can be used to decode the encrypted data.

Please follow below steps to create Facebook application:

  1. Login to your Facebook account and navigate to https://developers.facebook.com
  2. if you were already registered for Facebook developer account, you can skip this step and go to step #3 of this post. If you are not registered on Facebook developer account, then you need to follow these steps:

    • Click on next button from the popup

    • Enter your phone number and verify your account using text message or phone call.

    • It may be needed to Re Verify your account by Facebook.
    • Then enter verification code you got and click on the Verify button.
    • On the next screen, after verifying your account, 3rd step is to tell about you. Select Developer option here.

    • On welcome screen, click on Create First App button. Here you'll be asked for Display Name and Contact Email of your New App ID.
