Your app ID is a unique code assigned to your app when you create it in Intercom. There are a few ways you can find your app ID. 

The easiest way to find your app ID is to check the URL of any page you have open in Intercom. It's the code that comes after apps/ in the URL. So for this example app, if we check the URL we can see that the app ID is e8y21262

Your app ID is also available on the top right of the page in the API keys section of your app settings. Lastly, your app ID is available for quick copy/pasting in your Setup Guide, in the right-hand-side column.
