Introduction to Google Analytics 4 Event Builder

Google Analytics 4 Event Builder is a tool that allows users to create offline measurement protocol events and send this data to a Google Analytics 4 property.

So, let us understand what exactly measurement protocol events are and when to use them. 

Using the Event Builder tool, you can send data to a Google Analytics 4 property from your own servers that are not part of HTML or other offline POS machines. 

In the case of general analytics set up, Google Analytics tracking code is placed on every single page. When a user visits the page, it tracks the user journey with basic GA4 metrics (page view, bounce rate, user type, etc), whereas measurement protocol lets developers create HTTP post data requests and send this information to Google Analytics 4 servers. This way you can also track the user journey outside your website.

Now that we have understood the basics of Google Analytics 4 Event Builder, let’s see when to use this tool.

When do we use Google Analytics 4 Event Builder?

The GA4 Event Builder tool should be used when you have data that is offline and you want to send this data to Google Analytics. 

Let’s take an example; you are a business owner for a retail company that is available both online and offline. You would like to understand the overall performance of the business. To do so, both online and offline sales should be considered. 

In this case, you can use the Event Builder to send offline data to a Google Analytics 4 property. Now, that you have both online and offline data in Google Analytics, performance can easily be measured.

Overview of the GA4 Event Builder tool

<payload_data>

In hit summary, you have controls as shown below and these details need to be provided for creating the events.

API secret: This is the required query parameter, which is generated using Google Analytics 4 UI. Follow the below steps to create an API secret key.
