You can read more about the the information encoded within the consent string here: Transparency and Consent String with Global Vendor & CMP List Formats The Buyer should use the information in the consent string to ascertain which vendors and for which purposes the user gave consent. If the user has not given consent, then do not respond with an ad which utilises user information and neither access nor store information on the user’s device e.g. cookies, IDFA, fingerprints If the user has given consent, then identify all vendors to whom the user has given consent and for which purposes Buyers should also only use and store user data if the user has given consent to the buyer and only for the purposes for which the user has given consent Buyers should only allow third-party direct or redirect links to those who have received consent from the user https://vendor-list.consensu.org/v2/vendor-list.json If no consent is given, you cannot use personal data and may not have the right to use cookies. Each party is responsible for determining what that means for their business. If user consent explicitly states that it is not given, then do not respond with an ad which utilises user information and neither access nor store information on the user’s device e.g. cookies, IDFA, fingerprints For more information see the following links: https://github.com/InteractiveAdvertisingBureau/GDPR-Transparency-and-Consent-Framework https://gdpr-info.eu/ http://gdpr-demo.labs.quantcast.com/user-examples/cookie-workshop.html

Extended Identifiers¶

Supports the official Open RTB community extension for passing multiple third party user identifiers, see the official Extended Identifiers spec for more details.

This object passes any additional User IDs a Supplier, Consent Management Platform (CMP), Data Management Platform (DMP), or The MediaGrid may have for a user. There is a number of identity solutions that provide IDs for users that are not based on 3rd party data, and many of these solution providers extend their first-party data as offerings that can be used to offset the decline of 3rd party cookies.

The MediaGrid and many of our partners support these offerings and have build systems to collate, map, and make these IDs available to Buyers, who can use them to improve the robustness of targeted advertising. When the appropriate consent is in place (e.g CCPA, GDPR) The MediaGrid passes all and any correctly set ID in this field. The following IDs are the most commonly sent through The MediaGrid, but if you are looking for a particular ID in requests, you should check the source value to identify it. You can find a more extensive list of possible IDs on the Prebid User ID Module page

The TradeDesk ID known as the Unified ID 2.0 and passed as "uidapi.com", is based on a Single-Sign On (SSO) email validation service for publisher site access.
The TradeDesk ID known as the Unified ID 1.0 and passed as "adserver.org".You can read more about that here https://www.thetradedesk.com/us/about-us/industry-initiatives/unified-id-solution-2-0/unified-id-solution-1-0
The LiveIntent ID, passed as "liveintent.com", is built and authenticated daily through consent-based email, you can read more about here https://www.liveintent.com/identity-solutions/
The ID5 ID, passed as "id5-sync.com", enables publishers to create and distribute a shared first-party identifier, you can read more about that here https://www.id5.io/
The prebid managed SharedID, passed using "sharedid.org", see https://prebid.org/product-suite/sharedid/ for more details
Federated Learning of Cohorts FloC IDs may be passed in this field when coming from an Supplier using prebid, with the source given as "chrome.com".
The Intimate Merger ID is commonly used in the Japanese marketplace, with the source passed as intimatemerger.com.
The LiveRamp ID, passed as "liveramp.com", associates anonymous device IDs and other online customer IDs from publishers, platforms, or data providers with an IdentityLink (IDL) single person-based identifier. You can read more about it here https://liveramp.com/our-platform/identity-resolution/

Note

The LiveRamp ID is encrypted and only enabled for certain Buyers that have the business contracts in place to decrypt and use this ID, contact support@bidswitch.com if you are a LiveRamp partner.
The LiveIntent ID is only available to certain Buyers to whom LiveIntent wish to grant usage rights.

IDL passed using `"liveramp.com"`. SharedID passed using `"sharedid.org"`. FloC IDs may be passed using `"chrome.com"` if coming from prebid, but see the FloC Object also.
