reeview_uid cookie (14 days). The order tracking pixel reads that cookie at checkout and sends it as uid, so the order is attributed to the widget session.
You install one storefront pixel. The same pixel also attributes live shopping via reeview_lsid — see Live shopping order tracking. This page covers what is specific to widgets.
How attribution works
- The shopper interacts with a widget (stories, carousel, grid, floating, and similar).
- Videowise writes
reeview_uid. Campaign and experiment cookies may also be set (reeview_campaignfromvideowise_campaign_idin the URL,REEVIEW_SESSION). See Cookies. - On order confirmation, the pixel includes
uid(and campaign / experiment / referral values when present) in the tracking request.
uid. Shopify, Magento, SFCC, and custom/GTM installs all read reeview_uid.
On React Native, persist and send the same ID with getStoredData (uid) and trackingPixel.
