About

Official PostHog Zapier integration. Trigger Zaps from PostHog events and connect analytics data to thousands of apps.

What it does

This adapter creates a two-way automation bridge. A completed PostHog action can start a workflow with its event payload, while another workflow step can record a named event, user identity, properties, and optional timestamp in PostHog.

Why it's ranked here

A strong choice for focused PostHog automation because it supports both outbound action notifications and inbound event capture. Webhook subscriptions avoid polling for the main trigger, while dynamic organization, project, and action selectors reduce manual identifier entry.

What's good

Authentication validates personal access tokens and accepts US, EU, or custom hosts. Event properties receive useful type handling: valid JSON values become numbers, booleans, objects, or arrays, while invalid JSON remains text. Event capture automatically retrieves the selected project's token and marks Zapier as the source library.

Tradeoffs

The public surface is narrow: one visible trigger and one creation action. Action triggering requires a PostHog action to exist first. The annotation trigger is disabled, while organization, project, and action-definition triggers are hidden helpers. Automated tests shown here cover URL composition only, not authentication, webhooks, or event capture.

How to use it well

Use it when business workflows should react to a defined product behavior, or when another system must record a PostHog event without custom integration code. Configure the correct host and a fresh personal key. Look elsewhere for broad analytics querying, report export, annotation automation, or general project administration.

Technical notes+

src/index.ts registers custom authentication, a bearer-token beforeRequest hook, five triggers, and one create operation against zapier-platform-core 12.0.3. src/utils.ts builds host-aware HTTPS URLs and creates or deletes project hooks. src/triggers/action_performed.ts subscribes to action_performed; its fallback queries up to three recent matching events from the prior 30 days and reshapes rows into webhook-like payloads. src/creates/capture_event.ts fetches the project api_token, parses property values as JSON when possible, then posts to /capture. Its InputData names do not match every field read by perform, weakening type accuracy. src/test/utils.test.ts tests URL handling, including spaces, query strings, protocols, numeric segments, and bundle-provided hosts.
