Creative

A creative contains the contents of the ad. ie. The text, images, colors etc. that will be served to the end user.

A creative is part of an ad (which is combination of a placement and template).

Media Validation

Although aspect ratio constraints can be added to image fields when creating the template. We found that it can become messy (Eg. when images are a couple of pixels outside of a certain aspect ratio).

Due to this, we don't enforce a hard validation on uploaded media. However, when requesting an ad, the decision engine will return a media URL conforming to the constraints of the template field.

Eg: An image template field has a constraint of 1:1, but a 16:9 image is uploaded via the ad manager platform. We will accept this but the decision engine will return the media in 1:1 format, cropping the image from the center.
