Custom Events & Tags Available (v1)

Record your own events and tag sessions from your site’s JavaScript.

Where in the dashboard

Events — your custom events appear here, and tags become filterable attributes across the dashboard.

Key concept

Two calls cover most needs:

visz('event', 'signup_completed', { plan: 'free' });
visz('tag', 'beta_user');

• visz('event', name, props) records a named event with optional properties — a button click, a checkout step, a video play.
• visz('tag', name) marks the current session with a label you can filter and segment by later.

PII defense: never put raw personal data (emails, names, raw IDs) into props. The tracker applies a PII defense layer, but the right habit is to send hashed or non-identifying values. Properties are for analytics dimensions, not for storing user records.

Custom events plug into the rest of Visz: use them as funnel steps, filter recordings by a tag, or build a heatmap for tagged sessions only.
