Release Date: March 9th, 2026

Users can upload an HTML5 creative package as a zip file, containing all required assets. Once uploaded, the package is stored in Amazon S3 so it can be retrieved later for hosting on platforms such as DCM or Kevel. At this stage, the transfer to these hosting platforms will be handled manually. The platform will also provide a creative preview, allowing users to validate the uploaded assets before activation. Auditors will enter or update the HTML in the audit screen, and all existing audit fields remain visible and available within both the RTB Creative Audit screen and the upload/details windows. HTML5 creatives will participate in banner/display bid requests, enabling them to serve within the same inventory as standard display creatives.
