Setting Up Push Notifications with GA4 and Firebase on the Reactiv Platform
This guide provides a comprehensive walkthrough on setting up audiences in GA4 and delivering targeted push notifications in Firebase. Push notifications are a powerful way to engage users, ideal for sending broad announcements like product launches or for reaching users who have shown specific interest in products.
Audience Setup in GA4
Step 1: Access GA4 Account Settings
Log into your GA4 account.
In the bottom-left corner, select Settings.
Step 2: Select the Audience Panel
Go to Data Display and choose Audiences to manage and create target groups for your notifications.
Step 3: Initiate a New Audience
Click on New Audience to start defining the user segment.
Step 4: Create a Custom Audience
Select Start from scratch > Create a custom audience to define precise audience parameters.
Step 5: Define Your Audience for Push Notifications
In this example, we’ll set up an audience specifically for users who have viewed a particular product in your app.
Audience Name: Provide a unique, descriptive name for this audience.
Configuring Audience Filters
Filter #1 – Select the Reactiv platform:
In Add new condition, select Custom > reactiv_platform.
Click + Add Filter.
Set the filter condition to exactly matches (=).
Enter Reactiv Application as the value to capture all users who engaged with the main Reactiv app.
Filter #2 – Target users who viewed a specific product:
Click And to add another filter, refining your audience selection.
From Add new condition, choose Events > view_item. This selects users who triggered a view_item event.
Click Add Parameter.
Select Other > item_id to filter based on a specific product.
Retrieve the Product ID from your Shopify admin.
In Firebase, set the condition to exactly matches (=), and paste your product ID (e.g., 9043741049131).
Your audience settings should look similar to this:
Audience Retention
Optionally, set Audience Retention in the top-right to control how long users remain in the audience after meeting the criteria.
You can monitor high-level statistics for your audience, including its size, in the Summary section:
Step 6: Save Your Audience
Click Save to finalize this audience. Your audience is now ready to be used for targeted push notifications.
