We do not recommend using creatives as a custom code from third-party providers/ad servers.

IMPORTANT: adserver has no capability of implementing any JS tracking scripts (e.g. IAS) into HTML5 creatives. Therefore, one should place all the tracking scripts of this type directly in the creative code, just before </body> tag.

If the HTML5 creative contains video, due to the adserver size restrictions (HTML5 bundle or the total size of extracted files cannot exceed 1000KB), we recommend that all video files are hosted on external servers and then embedded in the creation's code.

Acceptable file formats:


The number of creatives (HTML5 or jpg / png / gif) allowed for this format is 3.
