Overview

Minimal working example demonstrating core PostHog functionality.

Prerequisites

• Completed posthog-install-auth setup
• Valid API credentials configured
• Development environment ready

Instructions

Step 1: Create Entry File

Create a new file for your hello world example.

Step 2: Import and Initialize Client

import { PostHogClient } from '@posthog/sdk';

const client = new PostHogClient({
  apiKey: process.env.POSTHOG_API_KEY,
});

Step 3: Make Your First API Call

async function main() {
  // Your first API call here
}

main().catch(console.error);

Output

• Successful API response confirming connection
• Console output showing:

Success! Your PostHog connection is working.

Error Handling

| Error | Cause | Solution | |-------|-------|----------| | Import Error | SDK not installed | Verify with npm list or pip show | | Auth Error | Invalid credentials | Check environment variable is set | | Timeout | Network issues | Increase timeout or check connectivity | | Rate Limit | Too many requests | Wait and retry with exponential backoff |
