Multi-site Setup

For different sites, you can configure different PostHog projects:

# For a specific website
bin/magento config:set --scope=websites --scope-code=site1 posthog/general/project_api_key "phc_SITE1_KEY"
bin/magento config:set --scope=websites --scope-code=site2 posthog/general/project_api_key "phc_SITE2_KEY"

How It Works

The module adds the PostHog tracking script to all frontend pages via the default.xml layout. The script is injected into the after.body.start container for optimal performance.
