I am promoting an affiliate offer online and the advertiser wants the GUID/IDFA info for every user who is interested in the offer. I know there is a Javascript code that auto generates GUID.
I would like that code incorporated in my Landing page so it auto generates a GUID every time user clicks on my offer. Here's the sample offer link:
http://www.xxxxx.com/aff_c?offer_id=4xxx&aff_id=xxxx&source={var1}&aff_sub={clickid}&aff_sub1={campaign.id}&creative_name={var2}&creative_size={var3}&google_aid=UDID
So once the user clicks on the offer link the UDID info is attached to the &google_aid variable.
