Hey there, integrating the Google Review flow into your existing comment portal is totally doable with Google's Places API. Let's break down exactly how to make that "Google" button trigger a review dialog when clicked:

First, you need to include the Google Maps JavaScript API with the places library in your portal's code. This gives you access to the review dialog functionality. Add this script tag to your page (preferably right before the closing </body> tag for better performance):

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_GOOGLE_CLOUD_API_KEY&libraries=places" async defer></script>

Note: Replace YOUR_GOOGLE_CLOUD_API_KEY with a valid API key from your Google Cloud Console, and make sure the Places API is enabled for that key.

Assuming your portal already has a list of social platform options, make sure your "Google" button has a unique ID so we can target it with JavaScript. For example:

<button id="google-review-btn" class="social-platform-btn">Google</button>

Keep the class consistent with your existing Facebook button to maintain visual uniformity.

Next, add a JavaScript snippet that listens for clicks on the Google button and launches the official Google Review dialog. You'll need your business's Google Place ID (find this by searching your business on Google Maps, clicking "Share", and copying the placeid parameter from the link).

// Wait for the page to fully load before attaching the handler
document.addEventListener('DOMContentLoaded', function() {
  const googleBtn = document.getElementById('google-review-btn');
  
  googleBtn.addEventListener('click', function(e) {
    e.preventDefault();
    
    // Replace with your business's actual Place ID
    const businessPlaceId = 'YOUR_BUSINESS_PLACE_ID';
    
    // Load the place service and trigger the dialog
    window.gapi.load('place', function() {
      const placeService = new google.maps.places.PlacesService(document.createElement('div'));
      
      placeService.getDetails({ placeId: businessPlaceId }, function(place, status) {
        if (status === google.maps.places.PlacesServiceStatus.OK) {
          // Open the native Google Review dialog
          google.maps.places.openReviewDialog({ placeId: businessPlaceId });
        } else {
          // Fallback: If the dialog fails, redirect to the direct Google Review page
          console.warn('Google Review dialog failed to load, falling back to direct link');
          window.open(`https://search.google.com/local/writereview?placeid=${businessPlaceId}`, '_blank');
        }
      });
    });
  });
});

• User Authentication: If the user isn't logged into their Google account, the dialog will automatically prompt them to log in—no extra code needed.
• API Failures: The fallback link ensures users can still submit reviews even if the dialog doesn't load (e.g., due to network issues).
• Styling: Make sure the button's hover/active states match your existing Facebook button to keep the UI consistent for users.

That's all! Now when users click the "Google" option in your portal, they'll see the official Google Review dialog where they can submit their rating and feedback seamlessly, just like the Facebook integration you already have.
