Connect Mixpanel in GrowSurf first

In GrowSurf, go to Campaign Editor > 4. Options > Integrations, open the Mixpanel card, and save the project token if needed. Keep the GrowSurf events enabled on the URLs where the referral portal and referred-friend conversion actually happen.

Verify the event stream in Mixpanel before you build the funnel

The funnel should be built from the GrowSurf event family: growsurf_signup, growsurf_share, growsurf_invite, growsurf_referral, and growsurf_referral_trigger. If those events are missing, fix URL whitelisting or event collection first and allow up to 15 minutes for Mixpanel processing.

Build the referral funnel around a real user path

• Use a referrer-side funnel like growsurf_signup to growsurf_share to growsurf_invite when you want to measure sharing intent.
• Use a referred-friend funnel like growsurf_referral to growsurf_referral_trigger when you want to measure how many referred signups become qualified referrals.
• Set the conversion window that matches your actual program cycle instead of using a default window that is too short or too long.

Add breakdowns and exclusions once the base funnel is correct

After the event order is stable, use Mixpanel funnel breakdowns with the user or event properties you already trust in your project, and use exclusions when you want to remove journeys that do not belong in the referral path you are studying.

Validate one participant path in Mixpanel's user detail view

Open a known referrer or referred friend in Mixpanel and compare the recorded event order against the same record in GrowSurf. That check keeps your funnel grounded in real participant behavior instead of a guessed sequence.
