Google Reviews Site Integration

I want visitors to leave a public Google review for my business without ever leaving my website. When they click “Write a Review,” they should be prompted to sign in with their Google account, see the familiar Google review window tied to my Google Business profile, submit their rating and comments, and then receive a confirmation—all seamlessly embedded in the current page.

You’ll need to:
• Implement Google Sign-In (OAuth 2.0) so the user is authenticated with Google.
• Launch the official Google review dialog for my Business Profile after sign-in and pass the correct Place ID so the review is posted to the right listing.
• Return a clear success or error message to the visitor and refresh the on-page reviews feed so the new comment is visible right away.
• Provide concise hand-off notes or code comments so I can maintain the integration going forward.

The site is already live, uses standard HTML/CSS/JS on the front end, and can accommodate a small back-end helper endpoint if needed (Node, PHP or similar—let me know what you prefer). Please follow Google API terms, keep the UX lightweight, and test on both desktop and mobile before delivery.
