Step 2: Configuring the pixel data script involves setting up Google Analytics

[DevCEDTeam]

Task # 1

Certainly! Configuring the pixel data script involves setting up Google Analytics to capture the required information when the tracking pixel is loaded. Here's a step-by-step guide to configure the pixel data script:

1. Set up Google Analytics:

   • Sign in to your Google Analytics account or create a new one.
   • Create a new property specifically for tracking email events.
   • Obtain the tracking ID associated with the property.

2. Add Custom Dimensions:

   • In your Google Analytics property settings, navigate to "Custom Definitions" and click on "Custom Dimensions".
   • Click on "New Custom Dimension" and define the dimensions you want to track, such as device and browser information.
   • Make note of the index assigned to each custom dimension. You will need these indices later.

3. Configure Google Tag Manager:

   • Sign in to your Google Tag Manager account or create a new one.
   • Create a new Tag in your desired container to capture the email open event.
   • Select the appropriate trigger for the Tag, which could be the URL of the tracking pixel.
   • Set up variables to capture the necessary information, such as the tracking code and custom dimensions.
   • Configure the Tag to send the event data to Google Analytics.
   • Save and publish your changes in Google Tag Manager.

4. Modify the Cloud Function:

   • Update the generateTrackingPixel Cloud Function to include the necessary information in the tracking pixel response.
   • To capture custom dimensions, you need to modify the Cloud Function to send measurement protocol requests to Google Analytics.
   • Install the axios library (using npm install axios) to make HTTP requests from the Cloud Function.

Here's an example of how to modify the generateTrackingPixel Cloud Function to include custom dimensions:

const axios = require('axios');

exports.generateTrackingPixel = async (req, res) => {
  const trackingCode = generateTrackingCode();
  const trackingUrl = `https://www.google-analytics.com/collect?v=1&t=event&tid=[YOUR_TRACKING_ID]&cid=${trackingCode}&ec=email&ea=open`;

  try {
    await axios.post(trackingUrl);
  } catch (error) {
    console.error('Failed to send event data to Google Analytics:', error);
  }

  const canvas = createCanvas(1, 1);
  const ctx = canvas.getContext('2d');
  ctx.fillStyle = '#000';
  ctx.fillRect(0, 0, 1, 1);

  const buffer = canvas.toBuffer('image/png');
  res.set('Content-Type', 'image/png');
  res.send(buffer);

  console.log(`Generated tracking code: ${trackingCode}`);
};

Make sure to replace [YOUR_TRACKING_ID] in the trackingUrl variable with the actual Google Analytics tracking ID obtained in step 1.

In the modified Cloud Function, the axios.post() call sends a measurement protocol request to Google Analytics to track the email open event. You can customize this request to include additional information like custom dimensions. For example, to include the device and browser dimensions, you would modify the trackingUrl as follows:

const trackingUrl = `https://www.google-analytics.com/collect?v=1&t=event&tid=[YOUR_TRACKING_ID]&cid=${trackingCode}&ec=email&ea=open&cd1=${deviceInfo}&cd2=${browserInfo}`;

In this example, cd1 and cd2 are placeholders for custom dimension indices 1 and 2, respectively. Replace deviceInfo and browserInfo with the actual values obtained from the email client's user-agent.

Remember to redeploy the Cloud Function after making these modifications.

That's how you configure the pixel

Task 2

Based on the Cloud Audit Logs you provided, it seems that the issues with the function deployment are related to missing dependencies and modules. The logs indicate that the module 'axios' cannot be found and that the required modules may not be listed in the package.json file.

To address these issues, you can update your code and configuration as follows:

1. Update the package.json file: Make sure to include the required dependencies, including 'axios'. Add the following entry to the dependencies section:

"dependencies": {
  "axios": "^0.21.1"
}

2. Ensure that you have the necessary module installation steps in your deployment process. After updating the package.json file, run the following command in the project directory to install the required modules:

npm install

3. Verify the file path: Double-check the file path and location of your index.js file. Ensure that it is in the correct directory and accessible to the Cloud Functions deployment process.

4. Redeploy the function: After making the necessary updates, redeploy your function to apply the changes. You can use the same deployment command you used before:

gcloud functions deploy <FUNCTION_NAME> --runtime=nodejs18 --trigger-http --allow-unauthenticated

Replace <FUNCTION_NAME> with the actual name of your function.

By following these steps, you should be able to address the missing module issues and deploy your Cloud Function successfully.

An issue with missing Google Cloud roles to gain access to dependencies and modules

caller is missing permission 'iam.serviceaccounts.actAs' on service account reverberant-joy-388014@appspot.gserviceaccount.com. Grant the role 'roles/iam.serviceAccountUser' to the caller on the service account reverberant-joy-388014@appspot.gserviceaccount.com. You can do that by running 'gcloud iam service-accounts add-iam-policy-binding reverberant-joy-388014@appspot.gserviceaccount.com --member MEMBER --role roles/iam.serviceAccountUser' where MEMBER has a prefix like 'user:' or 'serviceAccount:
