Track and Attribute Conversions Beyond Installs for Complete Funnel Visibility

We’ve taken conversion tracking to the next level. Beyond the standard install event, GSM360 now supports up to 10 custom conversion events via Server-to-Server (S2S) Postbacks, giving you greater flexibility and precision in measuring your funnel performance.

What This Means

This enhancement allows you to capture multiple key actions across your user journey: from registration and tutorial completion to purchases, subscription upgrades, and beyond. Whether you’re running app-to-web or web-to-app campaigns, S2S tracking ensures accurate attribution without relying on browser-based cookies or SDK dependencies.

How It Works

You can now configure up to 10 unique event postback URLs within your campaign setup:
  1. Each event can be mapped to a specific conversion step or goal.
  2. GSM360 will fire the corresponding postback whenever that event is triggered on your server.
  3. This enables end-to-end visibility into user engagement and monetization paths, ensuring your conversion data remains consistent across systems.

Why It Matters

  1. Improved Accuracy: Minimize data loss from client-side tracking and delayed signals.
  2. Enhanced Optimization: Feed richer conversion data into GSM360 for smarter bidding and targeting.
  3. Full-Funnel Insights: Go beyond installs - understand how users convert, re-engage, and generate value over time.


Use Cases

  1. Tracking post-install events such as sign-ups, purchases, or renewals.
  2. Measuring multi-step e-commerce or subscription funnels.
  3. Aligning conversion reporting between in-app analytics, MMPs, and backend systems.
