What it does

PostHog captures events, identifies users, and evaluates feature flags via the PostHog public API. Uses the project API key (phc_...) — no personal API key needed.

Setup

In PostHog, go to Project Settings → Project API Key and copy the phc_ value.
In FlowFn, go to Platform Tools → PostHog → Connect and provide api_key + region host (https://us.i.posthog.com or https://eu.i.posthog.com).
