Connect product analytics
Read active users and sign-ups from PostHog, Mixpanel or Amplitude, read-only.
Product analytics reads how people use your product from the tool you already track it in, so active users and sign-ups need no typing. That is the activation side of growth: it feeds Activation in Diagnosis and your Growth Score. Connect one of the three. Only the workspace owner can connect or disconnect.
| Tool | What you paste | Guide |
|---|---|---|
| PostHog | API key, project ID and host | PostHog guide |
| Mixpanel | Service account and project ID | Mixpanel guide |
| Amplitude | API key and secret key as a pair | Amplitude guide |
Make a read-only key
In your analytics tool, create a key that can read and nothing else. Each guide shows where.
Paste it and connect
On the page, choose your tool, paste the Key (and the Project ID, and Host (optional) for PostHog) and press Connect. We make one read-only call to check it before saving.
Choose your events
Pick the Core event (used the product) from the list we read from your tool, and optionally the Sign-up event (optional), then press Save events. We pick the likeliest ones for you to check. If an event is missing, choose Not listed, type it and type its exact name. Without a core event nothing can be read.
Stored encrypted
The key is never shown again. Replace key swaps it and Disconnect forgets it. Usage already read stays.
Read-only
We only read counts. We never send events and never change your project.
The connection proof on the page shows when data was last read and the active users it found. Test now checks the saved key again without changing anything. If the event list does not load, press Try again or type the name.
Vendor menus change. These steps were last checked against Surfil's connector page on 7 October 2026.
