Conversion Attribution

Conversion attribution is the process of linking a conversion event (like a purchase) back to the ad click that initiated the user's journey. Ring DAS uses user identifiers (LU, AID, EID) to track this relationship.

How Attribution Works

Step 1: Click Tracking

When a user clicks on an ad, the click is tracked via the Adclick API:

https://csr.onet.pl/{network}/trk/adclick/das,{lineitem},0?CS=tracking&lu={lu}

Example:

https://csr.onet.pl/6093132/trk/adclick/das,1844317,0?CS=tracking&lu=202601021108454216106685

Parameter	Description	Example
`{network}`	Advertising network ID	`6093132`
`das`	Format (fixed)	`das`
`{lineitem}`	TRACKING line item ID	`1844317`
`0`	Creative ID (fixed)	`0`
`CS`	Click source	`tracking`
`lu`	User identifier for attribution	`202601021108454216106685`

Step 2: Activity Event Tracking

When the user completes a purchase, send the purchased event to the Activity Pixel API:

https://csr.onet.pl/{network}/activity?event=purchased&lu={lu}&ord={order_id}&cost={total}&...

Example:

https://csr.onet.pl/6093132/activity?lu=202601021108454216106685&npa=0&actgid=63827&event=purchased&ord=02327411337&qty=2&cost=1598&tax=298.82&sitetype=cart&products=[...]

Step 3: Attribution Matching

The Ring DAS attribution engine matches user identifiers from the purchase event to the click event:

LU - Anonymous local user ID
AID - Hashed email set by Ring DAS
EID - Hashed email provided by client

Attribution logic:

Same identifier value = Same user
Within attribution window = Valid attribution
Conversion credited to the line item from the click
