How to integrate Firebase with Google Tag Manager?

 

Step 1: Set Up Firebase in Your Project

 

Ensure that you have a Firebase project set up. If not, create a new Firebase project in the Firebase console.

1. Open the Firebase console.
2. Click on "Add project" and follow the instructions to create your project.
3. Once your project is created, navigate to the Firebase dashboard.

 

Step 2: Add Firebase to Your App

 

Depending on whether you are working on an Android or an iOS app, the process of adding Firebase will be slightly different.

For Android:

• Add the Firebase SDK to your project using the following steps:

• Open your build.gradle file (project level) and add the Google Services classpath:

  
    buildscript {
        dependencies {
            // Add this line
            classpath 'com.google.gms:google-services:4.3.8'
        }
    }
    

• Open your build.gradle file (app level) and apply the Google Services plugin:

  
    apply plugin: 'com.android.application'
    apply plugin: 'com.google.gms.google-services'
    

• Add Firebase dependencies to your app's build.gradle:

  
    dependencies {
        // Add these lines
        implementation platform('com.google.firebase:firebase-bom:30.1.0')
        implementation 'com.google.firebase:firebase-analytics'
    }
    

For iOS:

• Add the Firebase SDK to your app using CocoaPods:

• Add the Firebase pod to your Podfile:

  
    platform :ios, '10.0'
  
    target 'YourAppTarget' do
      use\_frameworks!
  
      # Add the Firebase pod for Google Analytics
      pod 'Firebase/Analytics'
    end
    

• Install the pods by running the following command in your terminal:

  
    pod install
    

 

Step 3: Set Up Google Tag Manager Container

 

1. Navigate to the Google Tag Manager dashboard.
2. Click on "Add a new container".
3. Enter your container name, select the container type (iOS or Android), and click "Create".

 

Step 4: Add Firebase Analytics Tag in Google Tag Manager

 

1. In the Google Tag Manager console, click "New Tag".
2. Choose "Tag Configuration" and select "Firebase Analytics Event".
3. Under "Configure Tag", enter the event name and parameter settings you wish to log.
4. Set up the trigger for the tag (e.g., when a specific event occurs in your app).
5. Name your tag and click "Save".

 

Step 5: Link Firebase Analytics to Google Tag Manager

 

For the integration between Google Tag Manager and Firebase, you must ensure Firebase Analytics SDK is correctly installed as it acts as the intermediary for sending data.

• Ensure your Firebase has Google Analytics enabled:

• Navigate to Firebase console.

• Go to 'Analytics' from the side menu.

• Ensure Google Analytics is enabled.

• Validate Event Triggering:

• Ensure that required events and triggers are properly set in Google Tag Manager.

• Check if the data flows as expected by using the "Preview" mode in Google Tag Manager.

 

Step 6: Deploy Your Changes

 

1. Once your setup is done and validated, click "Submit" in Google Tag Manager.
2. Enter a name and description for your version and click "Publish".
3. Confirm and publish your container to make the changes live.

 

Step 7: Test the Integration

 

1. Monitor events in the Firebase console to ensure they are arriving as expected.
2. Use Firebase DebugView to verify events in real time.

By following these steps, you should be able to successfully integrate Firebase with Google Tag Manager and start managing analytics from within the Tag Manager interface.
