Connect PostHog to API Alerts

PostHog captures every event in your product. API Alerts pings you about the ones that matter. Wire them together through PostHog’s outbound webhooks and route the signals your team cares about to the channels your team actually works in.

Why pair them

PostHog is the right tool for analytics. It captures the entire stream (every pageview, every event, every interaction) all the way through to funnels, cohorts, and retention. Most of that volume lives inside PostHog forever and never demands real-time attention.

But some of those events are signals you want to be interrupted for. A new paid user. An anomaly crossing a threshold. A key conversion. A churn warning. A failed onboarding step. Those are exactly the events API Alerts is built for.

The relationship is complementary, not competitive. PostHog tracks everything. We ping you about what matters.

Connect with webhooks today

PostHog supports outbound webhook destinations. API Alerts has a webhook ingestion endpoint. You can wire the two together in a few minutes without waiting for a first-class integration.

  1. In PostHog, create a new webhook destination pointing at your API Alerts webhook ingestion endpoint
  2. Filter the events you want API Alerts to care about (by event name, property value, or cohort membership)
  3. API Alerts receives the payload, applies your routing rules, and fans it out to push, Slack, SMS, email, or any other destination you have configured

See the PostHog webhook documentation for the full configuration reference on their side.

First-class support coming

A first-class PostHog integration is on the post-launch roadmap. It will replace the webhook wiring above with a dedicated PostHog integration type in the API Alerts dashboard: pick events directly from an event picker, skip the manual webhook setup, and manage the connection from one place alongside the rest of your integrations.

Until then, the webhook path is fully functional. When first-class support ships, it will be a drop-in upgrade and your existing routing rules will continue to work unchanged.

  • Product analytics alerts. The generic pattern for routing high-signal events from any analytics tool to API Alerts. Uses this PostHog integration as its first-class implementation, with fallback implementations for Segment, RudderStack, Amplitude, Mixpanel, and Google Analytics 4.
