Product analytics platform API for querying events, managing feature flags, running experiments, and accessing session replays. Best for workflows that need to read analytics data, toggle feature flags programmatically, or automate experiment management. Unlike Mixpanel or Amplitude, PostHog is open-source with a self-hostable option.
9 example endpoints available through Lava’s AI Gateway. See the PostHog API docs for full documentation.
This provider requires your own credentials — connect your API key or OAuth account before use.
