X website tag image pixels need txn_id

The website tag loads uwt.js and fires adsct. txn_id is the conversion ID. Generated pixels send p_id=Twitter. Purchase fires send tw_sale_amount as a number. X documents twq, not this query.

tw_sale_amount is 10, not $10

Generated purchase pixels send a number. A currency symbol fails the format check.

Rule: vendor.x.param.tw_sale_amount.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
`txn_id`	required	It is the conversion or pixel ID the website tag fires. X documents the JavaScript tag rather than this query, so the rule is ecosystem evidence. Fix: Copy the conversion ID from the generated website tag so `txn_id` carries it.	`vendor.x.param.txn_id.missing` `vendor.x.param.txn_id.empty`	docs
`p_id`	recommended	Generated image pixels send `p_id=Twitter`. Fix: Keep `p_id=Twitter` from the generated website tag.	`vendor.x.param.p_id.missing` `vendor.x.param.p_id.empty` `vendor.x.param.p_id.invalid`	docs
`tw_sale_amount`	optional	Purchase fires send the revenue amount. Generated pixels use a number with no currency symbol. Fix: Set tw_sale_amount to a number such as 10 or 10.50, not $10.	`vendor.x.param.tw_sale_amount.empty` `vendor.x.param.tw_sale_amount.invalid`	docs
`tw_order_quantity`	optional	Purchase fires send the item count as an integer. Fix: Set tw_order_quantity to the item count, digits only.	`vendor.x.param.tw_order_quantity.empty` `vendor.x.param.tw_order_quantity.invalid`	docs
`twclid`	optional	It is the X click identifier from the landing URL. X documents twclid as a matching identifier on the pixel and the conversion API. Page fires without an ad click omit it. Fix: Set twclid to the click ID from the landing URL query, or drop the pair when there was no click.	`vendor.x.param.twclid.empty`	docs
