Taboola unip events need en

Taboola documents verifying event pixels by a unip request that carries en. page_view, purchase, and complete_registration are typical names. The tfa.js loader is vendor/taboola. S2S is vendor/taboola-s2s.

en is the event name

Taboola tells you to filter DevTools for unip? and look for en. A unip call without en is not an event pixel.

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
`en`	recommended	Taboola documents en on conversion event requests and says other unip requests are internal traffic. Because the endpoint matcher includes both, absence is a warning rather than an asserted transport failure. Fix: Send `en` with the Realize event name, such as `page_view` or `purchase`.	`vendor.taboola-unip.param.en.missing` `vendor.taboola-unip.param.en.empty`	docs
`revenue`	optional	It is the conversion value. Taboola documents an integer or decimal number, with no commas. Page views omit it. Fix: Send a number, such as `9.99`, or drop the pair on a page view.	`vendor.taboola-unip.param.revenue.empty` `vendor.taboola-unip.param.revenue.invalid`	docs
`currency`	optional	It is the revenue currency. Taboola documents a fixed list of three-letter codes, case-sensitive. Omit it to use the account default. Fix: Use a documented code such as `USD`.	`vendor.taboola-unip.param.currency.empty` `vendor.taboola-unip.param.currency.invalid`	docs
`quantity`	optional	It is the item quantity in the order. Taboola documents an integer. Fix: Send an integer quantity, such as `3`.	`vendor.taboola-unip.param.quantity.empty` `vendor.taboola-unip.param.quantity.invalid`	docs
`orderid`	optional	It is an order ID from the advertiser CRM. Taboola documents it as optional. Purchase fires often send it. Fix: Set orderid to the CRM order ID, or drop the pair.	`vendor.taboola-unip.param.orderid.empty`	docs
