Add a Facebook App ID

I need an application ID for creating my target audiance. Only thing is Facebook wants this type of id "You can only upload IDs for people that download or use your Facebook app. You can find the ID for your Facebook apps in App Dashboard"

Means it should be real application id, which people use, So is there anybody who can help me and give me an ID of any application in facebook. I have an application which I have created for social lead fox and now when I put that ID it doesn't create my audience.

I need only any type of id of facebook application which is real and people use it or can use it. I have tried to create my own just couldn't.
