I have an own OpenX server, serving ads in my websites. Now, I'm thinking of creating a FB app and want to add ads to it. I want to know if I can put my own ads on the app or I need to use one of the advertiser list here: https://developers.facebook.com/adproviders/
Thank you very much.
You can use your own advertising network inside of your app canvas, provided you follow Facebook's guidelines.
You cannot use it to control what ads Facebook displays alongside your app, to the right, in Facebook's ad designated area.
