Can I add and postback custom URL parameters in video ads?
I'm new to AdWords.
I am trying to set up a youtube video campaign with a custom parameter (see "custom param" right-hand column in the image):
I later want to set up a conversion postback URL for my "first-time open" event, and include the custom value (not just the campaign ID) in it. How do I do that?
Alternatively, assuming it's impossible, is there a way for me to see each campaign ID in the Adwords campaign manager UI above?
