Connect Amplitude in GrowSurf

Open the Amplitude integration card in your GrowSurf campaign, enter your Amplitude API key, and click Connect. If you already load Amplitude on the same pages, the API key is optional, but GrowSurf still recommends adding it so referral events are covered everywhere they need to fire.

Keep the GrowSurf event set enabled

GrowSurf enables the Amplitude event set by default after you connect. The core referral event family is growsurf_signup, growsurf_share, growsurf_invite, growsurf_referral, and growsurf_referral_trigger.

• Use growsurf_signup to confirm new referrers are joining the program.
• Use growsurf_share and growsurf_invite to measure sharing activity.
• Use growsurf_referral and growsurf_referral_trigger to separate referred signups from qualified referrals.

Confirm the stream in Amplitude Live Events

Before you trust any dashboard, open Live Events in Amplitude and make sure the GrowSurf events are arriving. GrowSurf's docs note that you should whitelist the referral portal and the referred-friend landing page in Amplitude so the full referral flow is tracked.

Open one participant profile and inspect the event properties

Click into one user in Amplitude and verify the event properties attached to the GrowSurf events. The user profile view is where you can spot mismatched participant emails, missing share URLs, or missing referral activity before those issues turn into reporting errors.

Build reporting from the verified event family

After the event stream looks correct, use the GrowSurf events in Amplitude charts, cohorts, or funnel reports. That gives your team one analytics layer for referrer joins, shares, invite sends, referred signups, and qualified referral triggers.
