vendor/mediamath-mobile · vendor documented

MediaMath mobile pixels need mt_id, mt_adid, mt_uuid, and mt_idt

MediaMath documents the native URL as /event/mob with mt_adid, mt_id, mt_uuid, and mt_idt. idfa is iOS, aaid is Android, waid is Windows. Browser /event/js and /event/img stay vendor/mediamath.

mt_idt names the advertising ID type

A mobile pixel with mt_idt=gaid is not one of the three native templates MediaMath documents.

Rule: vendor.mediamath-mobile.param.mt_idt.invalid

Rules

Codes are stable. A finding in CI, MCP, or the playground lands on the same id.

Field	Required	What it checks	Rule ids	Source
`mt_id`	required	It is the TerminalOne Pixel ID. MediaMath documents mt_id as required on /event/mob. Fix: Set mt_id to the Pixel ID from the MathTag on the website.	`vendor.mediamath-mobile.param.mt_id.missing` `vendor.mediamath-mobile.param.mt_id.empty` `vendor.mediamath-mobile.param.mt_id.invalid`	docs
`mt_adid`	required	It is the TerminalOne Advertiser ID. MediaMath documents mt_adid as required on /event/mob. Fix: Set mt_adid to the Advertiser ID from the MathTag on the website.	`vendor.mediamath-mobile.param.mt_adid.missing` `vendor.mediamath-mobile.param.mt_adid.empty` `vendor.mediamath-mobile.param.mt_adid.invalid`	docs
`mt_uuid`	required	It is the device advertising ID. MediaMath documents mt_uuid on every native /event/mob URL. Use a random UUID when Limit Ad Tracking is on. Fix: Send the IDFA, AAID, or Windows Advertising ID as mt_uuid. Randomize it when Limit Ad Tracking is enabled.	`vendor.mediamath-mobile.param.mt_uuid.missing` `vendor.mediamath-mobile.param.mt_uuid.empty`	docs
`mt_idt`	required	It is the advertising-ID type. MediaMath documents idfa on iOS, aaid on Android, and waid on Windows. Fix: Set mt_idt=idfa, aaid, or waid to match the OS that minted mt_uuid.	`vendor.mediamath-mobile.param.mt_idt.missing` `vendor.mediamath-mobile.param.mt_idt.empty` `vendor.mediamath-mobile.param.mt_idt.invalid`	docs
`mt_exem`	optional	It is a SHA-256 hashed email for MediaMath ConnectedID. MediaMath documents that hashing is not performed by the pixel. Fix: Hash the email with SHA-256 and send the hex digest as mt_exem.	`vendor.mediamath-mobile.param.mt_exem.empty` `vendor.mediamath-mobile.param.mt_exem.invalid`	docs
`mt_excl`	optional	It is a SHA-256 hashed account ID for MediaMath ConnectedID. Fix: Hash the account ID with SHA-256 and send the hex digest as mt_excl.	`vendor.mediamath-mobile.param.mt_excl.empty` `vendor.mediamath-mobile.param.mt_excl.invalid`	docs
`unhashed_email`	required	A parameter carries what looks like a raw email address. MediaMath documents mt_exem as a SHA-256 digest and says personally identifiable information must not be sent. Fix: Hash the email with SHA-256 and send it as mt_exem.	`vendor.mediamath-mobile.unhashed_email`	docs
