Is it possible to create a dynamic display ad that is using a HTML5 Bundle Template (ID: 419) that has dynamic properties based on a product feed?
I have researched Ad Customizers and how they are used to create a dynamic TextAd, but I don't seem to find the link between the Ad Customizers and the HTML5 bundle (e.g. created with Google Web Designer - based on a Dynamic Template).
I'm working in Ruby, but any explanation using SOAP will do.
