Setting up Google Analytics 4

There are 3 ways to send events to Google Analytics in the module

Enabling all at once is NOT NECESSARY, as it will cause data duplication or triplication, but with effort, you can send data to 3 (or more) different views.

Recommended method #1 - gtag.js

Method 1. Sending events via Google Tag - gtag.js

The simplest method; to make everything work well, it’s enough to connect Google Tag in the header in the <head> tag (can be entered in the counters tab) and specify the data stream identifier in the module.

In Analytics, go to Admin - Data Streams - select your stream or create a new one, and get the data stream identifier here

Nuances:

If multiple tags are used on the site, they need to be connected like this:

<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=TAG_ID_1"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'TAG_ID_1');
  gtag('config', 'TAG_ID_2');
</script>

If Google Analytics 4 is already connected via Google Tag Manager, you need to either disable the page send event in GTM tag settings

Or disable page view in Google Tag like this:

gtag('config', 'TAG_ID', {
  send_page_view: false
});

The point is to avoid duplicating the page view event page_view

You can also use tag grouping in this way

gtag('config', 'TAG_ID_1', { 'groups': 'group1' });
gtag('config', 'TAG_ID_2', { 'groups': 'group1' });

In the module, specify group1 instead of the data stream identifier, and events will be sent to 2 views simultaneously

Method 2. Sending events via dataLayer. Google Tag Manager

A fairly simple method, implemented according to the documentation

https://developers.google.com/tag-manager/ecommerce-ga4?hl=ru The link doesn’t work)

Enable it in the module, go to Google Tag Manager in administration - import JSON Container (click save as:)), and change the GA4_ID variable to your data stream identifier

Important - the analytics counter must be connected via Google Tag or in Google Tag Manager in the GA4 - SP SEO REMARKETING tag - enable sending page views

Method 3. Sending events via Measurement Protocol

For this sending method to work, the analytics counter must be connected via gtag.js or Google Tag Manager; the module is not a replacement for the counter!

- Enter the data stream identifier in the settings

- Select order statuses for sending or resending a purchase

- Get the API Key here

It’s also possible to send only transactions and refunds via Measurement Protocol

Used if payment modules don’t return the customer to checkout/success

Enable the parameter Send ONLY purchase and refund via MP (gtag.js and dataLayer don’t send the purchase). No need to enable the status.
