There is a setion on premium content an credits here Share items—ArcGIS Online Help | ArcGIS which enables you to control credit consumption, if that is what you are referring to.
Any credits that users consume by accessing premium content within the app will be charged to your organization. If you do not want to consume credits on behalf of users, do not enable any of the premium layers to be accessible through your subscription. This way, users will be required to provide their own credentials for consuming credits. However, keep in mind that if you do this, you will limit who can access your app to people who have an organizational account with privileges to access premium content. For public apps, you should either remove all premium content from the map or you should configure the app to have your organization incur the credit costs.
