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 Fyber Exchange
Getting Started
Contact your dedicated Programmatic Demand Manager to enable this feature:
- DSP to pass the lurl in the bid response, which allows Fyber to fire a loss notification when applicable
- For notifications on timeouts, please provide a static URL endpoint to your Demand Manager
- To receive transparency on the winning clear price, add the ${AUCTION_PRICE} macro to your tracking pixel and Fyber 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
Fyber's ad exchange uses RTB (real-time bidding) protocols to conduct an auction. Fyber Marketplace 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.
Note
Rejected bid responses appear as bid requests in Fyber's Buyer's Report.
Set out in the table below are the descriptions for each bid status.
| Bid Status | Definition | Corresponding Loss Notificatoin Status (LURL) |
|---|---|---|
| Adapter Failure | This metric is relevant for FairBid only. Fyber's SDK failed to activate the adapter of the mediation network | Not Applicable |
| Below the Floor Price | An invalid bid response where the demand source bid below the floor price sent on the bid request | 100 |
| Blocked Advertiser App | The bid response was rejected because the campaign's bundle corresponded to a blocked app by the publisher's app. | 206 |
| Blocked Advertiser Domain | The bid response was rejected because the campaign's advertiser domain corresponded to a blocked advertiser domain by the publisher's app. | 205 |
| Blocked Category | The bid response was rejected because the campaign's IAB category corresponded to a blocked category by the publisher's app. | 209 |
| Blocked on Creative | The bid response was manually blocked due to blacklisting of the creative ID due to creative issues or policy violations. | Not Applicable |
| Capped | This metric is only relevant to Traditional Mediated Networks buying FairBid mediated supply. The bid request was dropped when the frequency cap was reached. | Not Applicable |
| Demand QPS Throttling | A bid request that was never sent because it was blocked according to the DSP's set QPS (Queries Per Second) cap | Not Applicable |
| Empty Advertiser Domain | The bid response was rejected due to an empty advertiser domain | 6 |
| Failed Creative ID Blocked | The bid response was automatically blocked by an algorithm that blocks creatives with consistently low survival rate. | Not Applicable |
| Filtered Out for Optimization | A bid request that was never sent because it was blocked automatically due to Fyber's internal supply optimization algorithm that blocks unmonetized traffic. This metric can only be seen by internal Fyber account managers. | Not Applicable |
| HTTP Error | The bid response failed due to a web server error. | 3 |
| Incompatible SKAD Versions | The bid response was rejected because the SKAdNetwork version returned on BidResponse.seatbid.bid.ext.skadn.version was higher than the SKAdNetwork supported by the app and on the bid request | 214 |
| Invalid Advertiser Domain |
An invalid bid response where the demand source bids with an invalid advertiser domain.
What's invalid:
|
6 |
| Invalid or Malformed Bundle | An invalid bid response where the demand source bid with an invalid bundle format | 1010 |
| Invalid Response | The bid response failed because it was invalid. Common examples include, the JSON was invalid and the response was missing mandatory parameters. See our Demand Docs for a list of mandatory parameters. | 3 |
| Invalid SKAD Parameters | An invalid bid response where the demand source returned one or more invalid parameters on the BidResponse.seatbid.bid.ext.skadn Please refer to the IAB specifications to further details here. | 214 |
| Lost on Price | A valid bid response where the demand source lost the auction because the price returned was lower than another bid in the auction. | 102 |
| No Bid | The bid response returned an HTTP 204 "No Content" response signalling the bidder had no bid for the auction. | Not Applicable |
| Timeout | The bid response failed because it exceeded the timeout window (350ms for RTB Bidders). A best practice is for Demand Partners to pass a no bid instead of timing out. | 2 |
