Overview

What are Creative Approval Requests (CARs)?

Creative Approval Requests are a critical part of your screen network management workflow. When advertisers want to run their creatives on your screens, they submit a CAR containing the creative asset (image or video), advertiser information, and targeting details. As a screen network operator, you review these submissions and decide whether to approve or reject them based on your content standards and business requirements.

CAR Lifecycle

Pending: A new CAR arrives in your queue with status pending. The advertiser has submitted a creative for review.
Review: You examine the creative asset, advertiser information, and targeting details.
Decision: You either approve the creative to make it eligible for delivery, or reject it with specific reasons.
Active: Approved creatives with active campaigns become candidates for ad delivery on your screens.
