How does the Ad Exchange Creatives API help buyers ensure their creatives are set to successfully compete in the auction?

The Ad Exchange Creatives API allows buyers to programmatically check the approval status of their creatives. This is crucial because only approved creatives can compete in the auction. By easily and quickly identifying creatives that are disapproved or pending review, buyers can take corrective action, such as submitting new creatives or appealing rejections, ensuring their campaigns have eligible creatives ready to bid. While retrieving a list of active creatives, bulk submission, and assigning creatives to pre-targeting are also functionalities that can aid campaign management, they do not directly address the readiness of a creative to compete in the auction in the same way that checking its approval status does.
