Assigning auto generated GUID to a variable in offer link

I am promoting an afilliate offer online and the advertiser wants the GUID/IDFA info for every user who is interested in the offer. I have a Javascript code that auto generates GUID ( https://jsfiddle.net/xg7tek9j/7 ). I would like that code incorporated in my Landing page so it auto generates a GUID everytime user clicks on my offer.

Here's my offer link : http://xxxxx.com/aff_c?offer_id=cccxx&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 a random UUID is generated and assigned to &google_aid

i am interested PM your skype
