SAS Intelligent Advertising for Publishers supports dynamic tokens for string replacement in creative code content. For example, an ad call can pass in a key=value pair such as "/toys=nerfgun":
The creative content can then use the token %%TOYS%% to get the associated value "nerfgun":
<a href="%%CLICKURL%%?%%TOYS%%"><img src="%%MEDIA%%" width=728 height=90>
- where %%TOYS%% is replaced with "nerfgun" in the querystring of the click URL.
