I can set events through pageload rules but how do I set s.products? I'm trying to pass along product info with the purchase events but I don't see how to set this through DTM?
DTM currently does not offer a built-in form field for s.products. However, you can add it yourself.
Within the rule, go to Adobe Analytics > Custom Page Code and click on the Open Editor button.
Within this text box, you can write arbitrary javascript, including setting any Adobe Analytics variable.
If you need to reference a data element, you can use _satellite.getVar('data element name')
