Campaigns are a management layer in Attribution Analytics between your mobile app and your publishers. A campaign helps you manage multiple publisher relationships.
The functionality to first detect if a user is an existing user or not (i.e. already has the app in question installed) and to then open and redirect the user to said app via an invoke URL, otherwise known as 'deep linking', rather than redirecting them to the app store to download the app.
The payout for a publisher on the campaign which is associated to the mobile app.
Destination URL address for a campaign used to determine where people are taken when they click ad.
