For an ad server this feature is unique to AVID. You have the ability to track offers that have a one click up-sell by adding a transaction ID in your AVID pixel.
Let’s walk you through the steps of setting this feature up on your pixels:
1. Create Pixel (if necessary)
2. Open Get HTML Tag Screen
3. Enable “Track Multiple Sales” on the Get Pixel Screen
4. Copy pixel code onto the offer page and upsell offer page
5. Change the TransactionID on each page. With a unique Transaction ID, AVID will track a new sale even if the click ID and IP address are the same.
This feature works really well with offers that have a one click up-sell.
