No Bid Response

To answer to a bid request without making an actual bid, an HTTP response code 204 "No Content" should be sent.

Win and Billing Notification URLs

If either the nURL or the bURL are in the bid response and are valid URLs, ExoClick platform will send a GET request to them. These URLs can have a few tokens to be replaced by ExoClick before doing the GET:

${AUCTION_ID} - ID of the bid request; from "Bid Request Object -> id" attribute.
${AUCTION_BID_ID} - ID of the bid; from "Bid Response Object -> bidid" attribute.
${AUCTION_IMP_ID} - ID of the impression just won; from "Bid Request Object -> Impression Object -> id" attribute.
${AUCTION_SEAT_ID} - ID of the bidder seat for whom the bid was made; from "Bid Response Object -> Seat Bid Object -> Bid Object -> id" attribute.
${AUCTION_AD_ID} - ID of the ad markup the bidder wishes to serve; from "Bid Response Object -> Seat Bid Object -> Bid Object -> adid" attribute.
${AUCTION_PRICE} - Settlement price using the same currency and units as the account; from "Bid Response Object -> Seat Bid Object -> Bid Object -> price" attribute.
${AUCTION_CURRENCY} - The currency used in the bid (explicit or implied); for confirmation only.

Example:

https://mysite.com/my_notification_url?id=${AUCTION_ID}&bidid=${AUCTION_BID_ID}&price=${AUCTION_PRICE}&currency=${AUCTION_CURRENCY}

If you are using both nURL and bURL, ExoClick will make a call to both of them.
