Send events to PostHog, via Segment.

Segment allows you to easily manage data and integrations with services across your Growth, Product, and Marketing stack. By tracking events and users via Segment’s API and libraries, you can send your product’s data to all of your analytics/marketing platforms, with minimal instrumentation code. They offer support for most platforms, including iOS, Android, JavaScript, Node.js, PHP, and more.


This requires either PostHog Cloud, or a self-hosted PostHog instance running version 1.30.0 or later.

Not running 1.30.0? Find out how to update your self-hosted PostHog deployment!

You'll also need access to a Segment workspace.

Getting started

  1. In your Segment workspace, create a new project and enable PostHog as an integration. We are listed as a 'Destination' on Segment.
  2. Grab the PostHog API key from the 'Project Settings' page in PostHog.
  3. Use one of Segment's libraries to send events.
  4. See the events coming into PostHog.

Can PostHog with Segment do everything PostHog does by itself?

We are big fans of Segment, and many people in our team use it now or have used it in the past. However, it comes with some limitations for PostHog.

The Segment app gives you access to some things our browser JS library can do, but using Segment alone means you can't have autocapture, feature flags, session recording, heatmaps or the toolbar. Segment is also more easily blocked by ad-blockers.

To get around these limitations, you can install the PostHog snippet or posthog-js alongside your Segment integration. You can then use Segment for any custom events (for example segment.track('user sign up')), and posthog-js will automatically give you access to all the extra features.


Where can I find out more?

Further information is available in Segment's integration catalog.

Event Replicator

This app is currently unavailable while we develop a new export system . It will be back again soon! The Replicator app copies events from one PostHog instance to another, at the moment they are ingested. No changes are made to the events by this app if it runs in isolation. If this app is deployed in a chain then any changes made to the event data before the Replicator runs will also be copied to the new instance. Otherwise, no changes will be copied. Requirements The Replicator app requires…
