Program Events
A program on the Katalys Marketplace may have events available to you. When events fire, you can report on how many times that event happened for your traffic, and optionally configure a Postback to receive that event via a webhook, Google Ads, or Meta Ads integration.

Event Categories
All Katalys events are categorized into buckets for easy reference. Review the table below to understand how event categories help you generalize advertiser events into a funnel steps, and track performance for your traffic.
Event Category | Example Events | Description |
|---|---|---|
View |
| Views show user “awareness”. This is a traffic quality indicator identifying top-of-funnel users who did not immediately bounce. This helps measure the volume of real users and early funnel health. |
Engagement |
| Engagements show user “interest”. This means the user showed early soft-intent behavior by executing an action after initial landing. This pre-consideration marks a user as a potential prospect beyond just viewing. |
Progress |
| Progress shows user “consideration”. This means the user made it far enough in the funnel to believe the user shows strong intent to purchase. The user is still pre-purchase, but has become a qualified user, evaluating offer details. |
Conversion | Sometimes denoted by | Conversions happen when a Katalys billable event occurs. These events can be online or offline, and billable or non-billable (partial attribution). Conversions are fully-compatible with Postbacks, but they do not always appear as online events in Katalys event reporting. |
Non-Standard | (Advertiser-defined) | Some advertisers define events without a category because the event does not neatly map to our fixed vocabulary. These events are available for custom reporting, on a per-advertiser basis. |
Uncategorized | - | This category appears when an advertiser is sending events, but the events are not defined or categorized by the advertiser yet. |
