This wikiHow guide teaches you how to create a new App ID on the Facebook for Developers page so you can integrate Facebook into your app or website. We'll also show you how to find the App ID for an existing Facebook app, your secret key, and your Facebook user ID for an app or game.

Getting Your Facebook App ID

Log in to Facebook for Developers, and you will see the 15-digit App ID right below the app's name. If you don't have an App ID yet, click Create app, then complete the sign-up process to create your app and receive your Facebook App ID.

Select one or more use cases and click Next. Select any of the options that describe how you'll be using this app. If you don't see anything that describes your use case, select Other.
- If prompted to select an app type, select either Business or Consumer to continue.

Click Create app. If you have a business portfolio you want to associate this app with, you can select it from the menu first. Once you click Create app, your App ID will be generated, and you'll be taken to a page that allows you to add products to the app.

Search for your app. If you've already created the app on Facebook, it will be in this list. Scroll down to browse the list, or use the Search field at the top to find an app by name quickly.
- If you don't see the app, it may be under a different Business portfolio—use the "Business portfolio" menu on the left to select a different option.
You will see the 15-digit App ID right below the app's name. This number is unique to your app. You may need your unique App ID when you're setting up analytics, creating ads, launching a Facebook game, using the Threads API, setting up Facebook authentication for your mobile app, and more.^{[2]
