Parameter listing

Param Name	Legacy Parameter Name	Description	Required for Computer / Mobile (C/M)	Required for CTV	Example Value
session_id	impid	Unique, client-generated value that represents uninterrupted app interaction with content with gaps no greater than 30 minutes.	✔	✔	R487421B-XXXX-YYYY-3343-E3BBB46E44F2

publisher_id	pubid	This is a unique and persistent identifier supplied by the publisher of the connected device content, which represents the user that is exposed to the ad. This is equivalent to the advertiser ID on mobile devices.		✔	ab1cdef2-gh34-56ij-kl78-opq
hem_sha256	hem_sha256	SHA-256 hashed email Note: #Email Normalization rules applied before hashing	Preferred	Preferred	55C06A30DAA5D5F382FDEB8C702EC57875CC9D91A7C78 BB620053FD81DC4335C
uoo	uoo	User opt out flag based on OS “Limit Ad Tracking” or “Opt out of Ads Personalization” in mobile setting). This is an indicator for users who have opted out of ad tracking on their app and/or device. The absence of uoo in the tag is interpreted as an implicit opt-in (ie. not opted out). Nielsen offers an opt out from DAR measurement as described in the Nielsen privacy policy. Nielsen requires each application that contains active Nielsen measurement software to disclose that measurement software is included in that app, and provide access to an opt out mechanism: 0 = not-opted-out, 1 = opt-out	✔	✔	0, 1

publisher_name	pub	This is a Nielsen-supplied value representing the publisher of the content where the ad was served.	✔	✔ required for publishers	HOO
provider_user_id		Provider-specific device ID (must remain persistent indefinitely, must match ID in user mapping file, no collisions).		✔ required for providers	A769C2B-3CBD-5784-852F-C57875CC9D91A

app_name	c42=provapn	This is a publisher supplied value, passed either directly or via the platform provider, which represents the name of the app where the user was exposed to the ad. A separate app name will be provided for production use. Please request the app name from your Nielsen representative.		✔	hoolivideo
program_name	c43	This is a publisher supplied value, passed either directly or via the provider, which represents the program name of the content where the user was exposed to the ad. It is critical that these values are formatted and passed consistently. These values should be URL encoded.		✔ if tms_id not provided	Name Of TV Show S06+<S06:E13>
channel_name	ch_name	This is a publisher-supplied value, passed either directly or via the provider, which represents the name of the channel where the user was exposed to the ad. This value should be URL encoded.		✔ if tms_id not provided	abc
publisher_genre	c44=provcg	This is a publisher-supplied value which represents the genre of the content where the user was exposed to the ad.

device_group	c8=devgrp	This is the device type where the user was exposed to the ad. Nielsen relies on both the c8 and c10 values to make platform determination; these values must be consistently populated. If c8 or c10 are not present in the tag, then Nielsen collections will infer the device and platform based on the user agent present in the tag. If one of the below values cannot be determined, then the parameter should not be included in the call or should be left empty.	✔	✔	See #Device Group

Email Normalization

The below procedures should be performed before hashing emails:

• remove all leading and trailing whitespace
• force lowercase
• for @gmail.com addresses only:
• remove dots
• remove + suffix, including sign

Example: Art.Nielsen+JR@gmail.com → artnielsen@gmail.com

Device Group

This is the device type where the user was exposed to the ad. Nielsen relies on both the c8 and c10 values to make platform determination; these values must be consistently populated. If c8 or c10 are not present in the tag, then Nielsen collections will infer the device and platform based on the user agent present in the tag. If one of the below values cannot be determined, then the parameter should not be included in the call or should be left empty.
