Customer.io Hello World

Overview

Create a minimal working Customer.io example that identifies a user and triggers an event.

Prerequisites

Completed customerio-install-auth skill
Customer.io SDK installed
Valid Site ID and API Key configured

Instructions

Step 1: Create Basic Integration

// hello-customerio.ts
import { TrackClient, RegionUS } from '@customerio/track';

const client = new TrackClient(
  process.env.CUSTOMERIO_SITE_ID!,
  process.env.CUSTOMERIO_API_KEY!,
  { region: RegionUS }
);

async function main() {
  // Step 1: Identify a user
  await client.identify('user-123', {
    email: '[email protected]',
    first_name: 'Hello',
    created_at: Math.floor(Date.now() / 1000)
  });
  console.log('User identified');

  // Step 2: Track an event
  await client.track('user-123', {
    name: 'hello_world',
    data: {
      source: 'sdk-test',
      timestamp: new Date().toISOString()
    }
  });
  console.log('Event tracked');
}

main().catch(console.error);

Step 2: Run the Example

npx ts-node hello-customerio.ts

Step 3: Verify in Dashboard

Go to Customer.io dashboard
Navigate to People section
Search for "user-123" or "[email protected]"
Verify user profile shows attributes
Check Activity tab for "hello_world" event

Output

User created/updated in Customer.io
Event recorded in user's activity log
Console output confirming success

Error Handling

Error	Cause	Solution
401 Unauthorized	Invalid credentials	Verify Site ID and API Key
400 Bad Request	Invalid data format	Check attribute names and types
User not found	Identify not called	Always identify before tracking events
Event not showing	Dashboard delay	Wait 1-2 minutes and refresh

Examples

Python Hello World

import os
from customerio import CustomerIO

cio = CustomerIO(
    site_id=os.environ.get('CUSTOMERIO_SITE_ID'),
    api_key=os.environ.get('CUSTOMERIO_API_KEY')
)

# Identify user
cio.identify(id='user-123', email='[email protected]', first_name='Hello')
print('User identified')

# Track event
cio.track(customer_id='user-123', name='hello_world', source='sdk-test')
print('Event tracked')

With Anonymous User

// Track anonymous user with device ID
await client.identify('device-abc123', {
  anonymous_id: 'device-abc123',
  platform: 'web'
});
