Creatives from Authorized Buyers must be reviewed to ensure they do the following before they can serve:

- Align with publisher protections and controls
You can also review the status of creatives for associated buyer accounts through a Google Cloud Pub/Sub subscription.
Here are the steps in the life cycle of a creative:
- Creation: You can use - buyers.creatives.createto submit a creative for review.
- Review: Creatives must be reviewed before they can serve. The review process takes about 30 minutes. - If you've configured your account to watch for creative status changes, a message is logged to a corresponding Google Cloud Pub/Sub subscription for every creative status change. 
- Activation: Creatives are active immediately after approval. Active creatives can be placed in bid responses. Bids placed with disapproved creatives are filtered from the auction. 
- Modification: After review, you can use - buyers.creatives.patch, to update an existing creative. This automatically resubmits the creative for review.
- Deactivation: Creatives become inactive after being unused for 15 days. Inactive creatives aren't returned by the API. You can reactivate a creative by placing a bid with it.
