Connect PostHog: what to paste and what FoxPlug reads
An open-source product-analytics platform for events, funnels, session replay and feature flags. FoxPlug reads it only when you press Check for what's new. What you give it: Personal API key with Read on the listed rows (including Organization & account, Project), plus Project ID, and host only on the EU site.
Where to find it: In FoxPlug open Settings, then Publishing & integrations, then the Analytics section, and press How to connect next to PostHog. Faster: press / in Settings and type PostHog. Open it in FoxPlug
Steps
- Open https://us.posthog.com/settings/user-api-keys (if your PostHog address starts with eu, open https://eu.posthog.com/settings/user-api-keys instead). If you see a login screen, sign in the way you normally do, with the Google or GitHub button.
- Click "+ Create personal API key" and name it FoxPlug.
- Set these rows to Read: Product analytics; Web, marketing & revenue analytics; Events, people & data model; Session replay; Setup & data management. Then find "Organization & account" and set Project to Read as well. PostHog refuses the key without that one. Everything else stays on No access.
- Click Create key and copy the key that starts with phx_. PostHog shows it once.
- Project ID: look at your PostHog address bar. The number after /project/ is it (us.posthog.com/project/295721/... means 295721).
- Host: leave it out if your address starts with us.posthog.com. If it starts with eu, put a bar and https://eu.posthog.com after the ID, like 295721|https://eu.posthog.com.
- Paste the key and the Project ID into the two boxes and press Connect.
- Press the connect button in FoxPlug. FoxPlug checks the key or sign-in straight away and tells you in plain words if it was refused.

Good to know
- What to give: Personal API key with Read on the listed rows (including Organization & account, Project), plus Project ID, and host only on the EU site. Give it read-only access.
- What FoxPlug looks at: daily unique visitors; daily sessions; daily pageviews; rage and dead clicks by page; a leaving customer's last visit.
- Everything FoxPlug reads from PostHog, and what it never reads, is on its integration page.
- You can disconnect any time from the same place, and the stored key is deleted.
What it does not do
- bounce rate or session length (PostHog has no such field and FoxPlug does not compute one).
- session replays (the code queries events only).
