vendor/outbrain · ecosystem evidence

Outbrain pixels need ob_adv_id or ob_click_id

Noscript pixels send ob_adv_id. S2S conversions send ob_click_id. Outbrain documents the Marketer ID in GTM rather than this query, so the pack is ecosystem evidence.

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
`ob_adv_id`	optional	It is the Outbrain Advertiser ID. Generated noscript pixels send it. Outbrain documents the Marketer ID in GTM rather than this query, so the rule is ecosystem evidence. Fix: Set `ob_adv_id` to the Advertiser ID from Amplify Tracking.	`vendor.outbrain.param.ob_adv_id.empty`	docs
`ob_click_id`	optional	It is the click identifier S2S conversions send instead of `ob_adv_id`. Fix: Set `ob_click_id` to the `ob_click_id` captured from the landing URL.	`vendor.outbrain.param.ob_click_id.empty`	docs
`name`	optional	It is the event name on the S2S postback. Outbrain documents it on the unifiedPixel URL. Page-view noscript pixels send `ev` instead and omit `name`. Fix: Set `name` to the event name from Amplify, or drop the pair on a page-view pixel.	`vendor.outbrain.param.name.empty`	docs
`orderValue`	optional	It is the conversion value. Outbrain documents a decimal with a point, such as `4.99`, not `4,99`. Fix: Send a number such as `4.99`, with a point and no currency symbol.	`vendor.outbrain.param.orderValue.empty` `vendor.outbrain.param.orderValue.invalid`	docs
`orderId`	optional	It is the advertiser order ID. Outbrain documents it so two conversions from the same user in a short window are not deduplicated. Fix: Set orderId to the order ID, or drop the pair.	`vendor.outbrain.param.orderId.empty`	docs
`currency`	optional	It is the orderValue currency. Outbrain documents this fixed list of three-letter codes. Fix: Use a documented code such as `USD` or `GBP`.	`vendor.outbrain.param.currency.empty` `vendor.outbrain.param.currency.invalid`	docs
`identifier_required`	required	The pixel has neither `ob_adv_id` nor `ob_click_id`. Generated fires carry one of the two. Fix: Send `ob_adv_id` for a noscript or page-view pixel, or `ob_click_id` for an S2S conversion.	`vendor.outbrain.identifier_required`	docs
