Win Notifications
If an nurl is provided in the bid response, Chartboost will send the win notification via server-side HTTP GET requests. Standard OpenRTB 2.5 macro replacement is supported here.
Supported nurl macros:
${AUCTION_ID}${AUCTION_BID_ID}${AUCTION_IMP_ID}${AUCTION_SEAT_ID}${AUCTION_AD_ID}${AUCTION_PRICE}${AUCTION_CURRENCY}
