Supply Partners - Bid response

  • Artikel

Warning

We have disabled the Supply Integration (ASI) protocol (formerly AppNexus Supply Integration) for server-side supply integrations beginning on October 1st, 2017. We strongly encourage that you migrate your supply to the OpenRTB protocol. Everything in this section is legacy content.

After you send a bid request, Xandr returns a bid response in JSON format. This page explains the possible JSON fields and their values. The Examples at the bottom of the page show the fields that are returned when:

  • Xandr submits a bid
  • Xandr does not submit a bid - No bid available
  • Xandr does not submit a bid - Error
  • Xandr submits a VAST video creative (NOT YET SUPPORTED)

Tip

If a Xandr bid wins your auction, you should insert the winning bid price into the %%pricepaid%% macro of the ad_tag before placing the tag on the web page.

JSON fields

Field Type Description Example
external_auction_id string The ID of the supply partner auction, as sent in the bid request. "A4s24536"
appnexus_auction_id int Xandr holds its own auction to select the bid to submit for your auction. This is ID of the Xandr auction event. 4396943919143109134
bid decimal The CPM value of the Xandr bid. 0.206367
creative_id int The ID of the creative that is served if Xandr wins your auction. 345634
landing_page_url string The landing page URL of the creative. "www.landingpage.com"
brand_id int The Xandr ID for the brand of the creative. To map brand IDs to names, use the Brand Service. 12
buyer_member_id int The ID of the member that owns the creative. 3453
no_bid boolean If true, Xandr does not have a bid for your auction. false
request_error boolean If true, an error prevented Xandr from submitting a bid. false
request_error_id int The ID of the error. This field is returned only when request_error is true. For all the possible error IDs and their meanings, see Errors section below. 3
ad_tag string The ad tag that is placed on the web page if Xandr wins your auction.

Note: If you wish to track clicks, Xandr can add a macro for your click URL: &pubclick=%%pub_click_url%%.

To learn more about this functionality, reach out to your implementation team.		 See examples below.

Supply templates

For VAST video creatives, if you require custom parameters not normally included in the ad_tag of the bid response, you can ask Xandr to build a supply template for you. Here's how it works:

  1. You communicate directly with your Xandr representative about the custom parameters you would like returned for VAST video creatives.
  2. If Xandr agrees with your request, Xandr builds a supply template for you and sends you the ID.
  3. In your bid requests for VAST video creatives, you include the supply template ID in the template_id field.
  4. In bid responses, the supply template adds your custom parameters to the <Extensions> section of the ad_tag.

Example

Let's say you want Xandr to include the following supplementary information for VAST video creatives:

  • Bidding strategy (CPM, CPC, etc.)
  • Currency
  • Source of the bid

The supply template that Xandr would build for you would add this information to the <Extensions> section of the ad_tag:

Note

For the full bid response for a VAST video creative, see the Examples below.

Errors

When an error prevents Xandr from submitting a bid, the request_error_id in the response helps you diagnose the problem.

request_error_id Meaning
1 The syntax of the bid request was incorrect.
2 The member ID in the request could not be parsed.
3 The request did not map to a Xandr user ID.
4 The bid request did not include external_auction_id.
5 The request did not map to a placement.
6 The Xandr auction failed.
7 The requested ad_format did not match the placement format.
8 The inventory (e.g. page_url) or user (e.g. ip_address) passed is blocked by Xandr.**
9 The ad_format parameter (required) was not passed in the request.

Note

**Error ID 8 will also trigger if the domain passed is excluded by the global targeting profile of the buying member.

Xandr submits a VAST video creative (NOT YET SUPPORTED)

When Xandr submits a VAST video creative:

  • The creative is passed as escaped VAST XML in the ad_tag field.
  • If the bid wins your auction, you must unescape the content before placing it on the page.
  • If the bid wins your auction, you must insert the winning bid price (in CPM) into the %%pricepaid%% macro in the ad_tag.
  • If you have asked Xandr to build a supply template that passes custom parameters in VAST creative bids, those custom parameters will appear inside the <Extensions> tag of the XML within the ad_tag. In the example below, the supply template has added supplementary information about the price of the bid. For more details about about supply templates, see Supply Templates above.

Tip

Following industry standard practice, Xandr does not log a VAST impression on win. Instead, the impression is logged only once the video starts (user clicks play, etc.).
