Your Gist project ID is a unique code assigned to your app or project when you create it. It is much similar to the user ID that we give to your users.
There are a few ways you can find your project ID.
The easiest way is to check the URL of any page you have open in Gist. It's the code that comes after ‘projects/’ in the URL. So for this example app, we can see that the code after projects/ is zxyumdx6.
Hence the ID of this particular project or app is zxyumdx6.
Your project ID is also available in the Project section on Gist.
Click on the ‘Projects’ button available at the bottom left of your screen, click on ‘Projects List’ and then click on the ‘<>’ button, and then go to ‘WordPress’. You will be able to see the project ID on this screen.
Lastly, your app ID is available for quick copy/pasting in your Setup Guide, in the right-hand-side column.
