Benefit to DSPs

Bid Loss Notifications provide granular, immediate feedback on a per impression basis, helping DSPs:

• Receive auction transparency on pricing and blocks (bid below the floor, lost to a higher bidder, advertiser blocked, etc.)
• Uncover technical issues that prevent successful bids (timeout, invalid adomain, etc.)
• Understand the winning clear price of the auction in order to improve pricing strategies 

Requirements

• Partner must be setup as an RTB enabled bidder on the DT Exchange

Using Bid Loss Notification

Contact your dedicated Programmatic Demand Manager to enable this feature:

1. DSP to pass the lurl in the bid response, which allows DT to fire a loss notification when applicable
2. For notifications on timeouts, please provide a static URL endpoint to your Demand Manager
3. To receive transparency on the winning clear price, add the ${AUCTION_PRICE} macro to your tracking pixel and DT will return the winning clear price in $USD

What's Not Supported?

We do not support error code 0 (win) for the lurl. For win notifications, please use the nurl parameter.

Bid Statuses

DT's ad exchange uses RTB (real-time bidding) protocols to conduct an auction. DT Exchange or our publishers, can filter out or reject certain bids for a variety of reasons.

Each bid response filtering mechanism is detailed below in the Bid Statuses section.

Set out in the table below are the descriptions for each bid status.
