Preview an ad
Overview
The Preview ad feature allows traffic managers to verify how a creative appears on a retailer’s website and easily capture screenshots using only the selected creatives for a given targeted context.
The feature supports both JavaScript (JS) tag and Server-to-Server (S2S) integration modes, providing flexibility across different delivery setups.
Previews are only available for running Guaranteed campaigns at the line item level.
Ad preview mechanism
To activate a preview, enter a preview token into the retailer’s search bar. This method simulates live ad delivery without relying on browser cookies, offering a straightforward and reliable preview experience.
Each preview session remains active for 5 minutes, after which the token must be re-entered to continue viewing the creative.
Viewer users can use this feature only for line items in Review status. If a line item isn't in Review, these users cannot change its status or use the feature.
