Using Assets

Topsort supports many types of assets that can be used in campaigns. See below for supported asset types.

How it Works

Uploading Assets

While creating a campaign, you can upload assets to banner or sponsored brand campaigns. These assets can be images, videos, html or externally hosted files (a url). These assets will be returned as part of a winning auction and suitable for inclusion in the ad creative.

You can also use our Assets API, to create and manage assets without necessarily using them in campaigns.

Supported Asset Types

We support the following asset types:

  • Images: PNG, JPEG, GIF and WEBP.
  • Video: MP4, WEBM, MOV.
  • External URL (can be anything you want to use from a third party service)
  • HTML: HTML code that can be used to render a custom creative. We return the link to said HTML file which you can include via an <iframe> tag.
  • JSON

Asset Size

  • For images we support up to 50MB.
  • For videos we support up to 200MB.
