I’ve added support to do a prefetch and get a callback when there is an ad available. I also added the GiftGaming ad tracking parameters to increase CPM. To prefetch an ad do the following:
msg.post("url_to_giftgaming_go", "prefetch", { apikey = "12345abcde", test = false })
This will post either a prefetch_ok or prefetch_failed message back to the sender. If prefetch_ok is received there’s a 30 second window to post a show message to show the prefetched ad.
