PostHog

If your application already tracks events with PostHog, the Altertable JavaScript SDK can forward those captured events into the product_analytics catalog. Your existing PostHog tracking calls can stay in place.

Connect PostHog

Enable Product Analytics and copy its API key. Initialize Altertable before PostHog:

import posthog from 'posthog-js';
import { altertable } from '@altertable/altertable-js';

altertable.init('YOUR_API_KEY', {
  adapters: { posthog },
});

posthog.init('POSTHOG_KEY');

While the adapter is configured, Altertable's own track, page, identify, alias, updateTraits, and reset calls are ignored, and its automatic capture stays off. Altertable still applies its tracking consent setting. Forwarded events do not pass through transformEvent.

PostHog events need a distinct ID and timestamp. Cookieless PostHog events are not supported.

For events tracked directly with Altertable, see Track.
