Diagram showing website events flowing into OneView, which processes and deduplicates data before sending to Meta, Google, and TikTok APIs.

OneView is a conversion gateway between your website and advertising platforms.

OneView is a full server-side tracking platform that acts as a conversion gateway between your website and advertising platforms. Unlike proxy solutions that simply relay events, OneView is a stateful platform that handles data collection, compliance, deduplication, and integrations automatically.

​
How it works

OneView is stateful — it maintains memory and context between requests. This enables capabilities that other solutions cannot provide.
OneView processes events through a complete pipeline:

Common questions

OneView acts as an intelligent conversion gateway between your website and the ad platforms you use.It collects the events you send, validates and enriches them, removes duplicates, and delivers verified conversions through each platform’s official API.By providing cleaner, more complete conversion data, OneView improves bidding accuracy and campaign optimization — all without ongoing engineering work.
GTM Web runs entirely in the browser and depends on client-side JavaScript execution. This means data collection can be affected by asynchronous script loading, single-page-app routing, network latency, flaky retry logic, or users navigating away before events finish sending.OneView runs server-side, where events are processed deterministically and independently of the user’s device or browser.
GTM Server-Side is a configurable proxy that forwards events as they arrive.OneView is a stateful platform — it maintains context between events, automatically enforces consent, retries failed deliveries, and deduplicates conversions.The result is higher data quality and zero maintenance — no custom servers, containers, or scripts to manage.OneView’s stateful architecture enables features that stateless proxy solutions cannot provide:
