How to Trigger Session Recordings Based on Specific UTM Parameters?

·Feb 13, 2026 11:31 AM·

Is it possible to trigger session recordings only when certain UTM conditions are met? For example, if UTM source contains XYZ, start session recording. Otherwise, don't start.

It’s not documented as a built‑in, declarative option (e.g. “only record when UTM source = X”), but you can achieve this behavior using manual start/stop of Session Replay in your own code.On Web, you can: 1. Initialize Mixpanel with record_sessions_percent: 0 so nothing is recorded by default. 2. In your app, read the UTM parameters from the URL. 3. If the condition matches (e.g. utm_source contains XYZ), call mixpanel.start_session_recording() to force recording on; otherwise, do nothing.start_session_recording() “forces recording to begin, regardless of the record_sessions_percent init option,” and is explicitly recommended for cases like “only record certain types of users” or “only record users utilizing certain features.”[JS replay capture]Example pattern (pseudo‑code): js mixpanel.init('<YOUR_PROJECT_TOKEN> ', { record_sessions_percent: 0 // default: no sessions recorded });LBKS// after init, once you can read URL params: const params = new URLSearchParams(window.location.search); const utmSource = params.get('utm_source') || '';LBKSif (utmSource.includes('XYZ')) { mixpanel.start_session_recording(); }LBKSYou can similarly call mixpanel.stop_session_recording() when a user navigates to areas you don’t want recorded.[JS replay capture; Replay privacy controls]The docs do not mention UTM‑based conditions specifically, but they do support this general “only record certain users/contexts” pattern via manual start/stop.
