User Ext Object Properties¶

User Ext Object Properties¶
Value	Type	Description
ug*	integer	User group set up for the target user during cookie syncing, for example `1`. This takes the following values: `0`: unmatched user `1`: matched user `2` - `99`: custom user group.
cookie_age*	integer	Number of days since the user cookie has been dropped, for example, `10`
floc*	object	Cohort ID that is common to a large cohort of users with similar browsing habits. Currently the cohort ID is simulated by the exchange (as opposed to by the browser). When simulated cohort ID is provided, traditional pseudonymous cookie-based user identifiers or device advertising identifiers would not be populated. Experimental feature; may be subject to change. See https://github.com/WICG/floc for more background on FLoC. Note In the event FLOC is being used there should be no `user.id` or `user.buyerid` present.
digitrust*	object	Deprecated since version 5.3: passing this value moved to the `xuid` object Container object for the DigiTrust ID and related attributes, see the DigiTrust Object object for more details.
xuid*	array of objects	Contains cross-platform user ID information for the following possible vendors: `"nonID"`, `"TDID"`, `"id5"`, `"IDL"`, `"sharedID"`, see Cross-Platform UID Deprecated since version December: 2020, replaced by `eids`
eids*	array of objects	Contains the Extended identifiers object, see the Extended Identifiers section for details
google_consent*	array of integers	Set of IDs corresponding to providers for whom the publisher has provided user consent using Google vendor list. A mapping of provider ID to provider name is posted at https://storage.googleapis.com/adx-rtb-dictionaries/providers.csv Deprecated since version 5.3. Replaced by the `consented_providers_settings` object, with the IDs passed in its `consented_providers` array.
impdepth*	int	The count of impressions for a specific placement type in a given app session. The impression depth is reset once the session ends, e.g `2`
sessionduration*	int	The total duration of time a user has spent so far in a specific app session expressed in seconds. For example, a user has been playing Word Game for 45 seconds, e.g. `45`
consented_providers _settings*	object	Passes a set of IDs corresponding to providers for whom the publisher has provided user consent using Google vendor list. See the Consented Provider Settings
consent*	string	Passes the Transparency & Consent Framework string. The current valid version of this string is v2.0. 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

Consented Provider Settings¶

Consented Providers¶
Value	Type	Description
consented_providers	array of integers	Set of IDs corresponding to providers for whom the publisher has provided user consent using Google vendor list. A mapping of provider ID to provider name is posted at https://storage.googleapis.com/adx-rtb-dictionaries/providers.csv

FloC Object¶

FloC Object Properties¶
Value	Type	Description
id	string	The value of a cohort ID – a string identifier that is common to a large cohort of users with similar browsing habits.
type	integer	Identifies the method of generating the cohort ID, see this Google whitepaper for more details: Evaluation of Cohort Algorithms for the FloC API FLOC_TYPE_UNKNOWN = `0`; Default value that should not be used. SIMULATED_AFFINITY_CLUSTERING_CENTROID_VERTICAL = `2`; FLoC simulated using affinity hierarchical clustering with centroids and feature extraction based on Topic categories as described in the whitepaper. SIMULATED_SIMHASH_SORTING_LSH_DOMAIN_ONE_HOT = `3`; FLoC simulated using SortingLSH clustering algorithm and Domain One-hot encoding feature extraction as described in the whitepaper. FLoC simulated using a k Random Centers locality-sensitive hash function as described in github.com/google/ads-privacy/ blob/master/proposals/FLoC/k-random-centers.md with Domain TF-IDF feature extraction as described in the whitepaper. KCENTER_DOM_FILTERED_TFDIF = `4`;

DigiTrust Object¶

Object Properties¶
Value	Type	Description
id	string	User ID as provided by DigiTrust.
id	string	User ID as provided by DigiTrust.

Cross-Platform UID¶

Important

This field has been deprecated and replaced by the IAB OpenRTB community extension, see the Extended Identifiers section. Until all partners have switched over to the replacement field, you will see both objects in bid requests.

Cross-platform User ID object used to pass any additional User IDs the Supplier may have for this user.

xuid Object Properties¶
Value	Type	Description
provider	string	(Required) The provider of the additional User ID value, the possible values are: `"nonID"`, `"TDID"`, `"id5"`, `"IDL"`, `"sharedID"`
id	string	(Required) User ID with this provider.

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 BidSwitch 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.

BidSwitch 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) BidSwitch passes all and any correctly set ID in this field. The following IDs are the most commonly sent through BidSwitch, 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
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.

eids Object Properties¶
