Send event to Google Analytics 4

This hook enables you to send event data from your Shopify store directly to Google Analytics 4 using the Measurement Protocol. Use it to track purchases and other customer interactions without additional client-side code.

Prerequisites

• Google Analytics 4 API Secret
• Google Analytics 4 Measurement ID
• A Shopify store with Cloudhooks installed

Configuration

1) Set up trigger

Create a new hook in the Cloudhooks dashboard with "An order is created" as your trigger event.

2) Configure authentication

Update these variables in the hook code with your Google Analytics credentials:

const API_SECRET = '[Your GA4 API secret]';
const MEASUREMENT_ID = '[Your GA4 measurement id]';

3) Implement the hook

Copy and paste this code into your hook editor:

You can send recommended events and custom events to Google Analytics via the Measurement Protocol .

The following example sends a purchase event to Google Analytics (the hook expects an order payload):

const API_SECRET = '[Your GA4 API secret]';
const MEASUREMENT_ID = '[Your GA4 measurement id]';

module.exports = async function(payload, actions, context) {
  const gaUrl = 'https://www.google-analytics.com/mp/collect' +
                  `?api_secret=${API_SECRET}` +
                  `&measurement_id=${MEASUREMENT_ID}`;
                  
  const gaData = {
    client_id: 'Cloudhooks',
    user_id: payload.customer.id.toString(),
    events: [
      {
        name: 'purchase',
        params: {
          transaction_id: payload.order_number.toString(),
          currency: payload.currency,
          value: parseFloat(payload.current_total_price),
          items: payload.line_items.map( (item) => {
            return { 
              item_name: item.name,
              quantity:  item.quantity,
              price:     parseFloat(item.price)
            };
          })
        }
      } 
    ]
  };

  try {
    // Google Analytics always returns HTTP 200
    // No need to check return value
    await actions.http.post(
      gaUrl, gaData,
      {headers: {'Content-Type': 'application/json'}}
    );
  } catch (err) {
    console.log('GA error: ' + err);
  }
};

Testing

Test your hook using Cloudhooks' test payload feature before activating it in production. Use a sample order payload from your store.

Notes

• It typically takes 24-48 hours for events to appear in Google Analytics reports.
• This example demonstrates a purchase event, but you can modify it to send any recommended events or custom events.
