Customer.io Enrichment Integration

Setup Guide

Create API authentication

Store Factr API key in Customer.io environment variables.

Set up event-triggered enrichment

Use Customer.io events to trigger Factr enrichment via webhooks.

Store enrichment in attributes

Map Factr response fields to Customer.io custom attributes.

Build journeys on enrichment data

Create dynamic journeys that branch based on enriched attributes.

Code Example

JavaScript / Node.js

// Customer.io webhook enrichment handler
app.post('/webhooks/customer-io', async (req, res) => {
  const { data } = req.body;
  const email = data.customer.email;

  // Enrich via Factr
  const factrRes = await fetch('https://factr.polsia.app/api/enrich', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      email,
      apiKey: process.env.FACTR_API_KEY
    })
  });

  const enrichment = await factrRes.json();

  // Update Customer.io attributes
  const cioRes = await fetch('https://api.customer.io/v1/customers/' + data.customer.id, {
    method: 'PUT',
    headers: {
      'Authorization': 'Bearer ' + process.env.CUSTOMER_IO_TOKEN,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      attributes: { enriched_fact: enrichment.fact }
    })
  });

  res.json({ success: true });
});
