Viant Universal Pixel Tag Setup Guide

About

The Viant Universal Pixel tag sends client-side conversion and engagement events from your site to Adelphic DSP by Viant for measurement, optimization, and attribution.

Use this tag to track standard funnel events (such as Page View, Add to Cart, Initiate Checkout, Purchase, Lead) and pass rich transaction details, customer identifiers, and product data to Viant.

Built-in support for Universal Pixel ID (UPID), customer IDs, revenue, currency, and custom parameters helps improve campaign performance, reporting accuracy, and troubleshooting across Viant’s advertising platform.

  • Dynamically override the standard config values

  • Currency (_ccur)
