Google OAuth, PHP-Symfony, API-Platform, JWT


In this symfony api project, I explained how to authenticate users with their Google accounts.


Symfony application using Google OAuth for authentication. When a user signs in through Google, our system will check if the user already exists in our database. If not, it will create a new user account. Once authenticated, either as a new or existing user, our application will generate a JSON Web Token (JWT). Built on the API Platform.


Creating Symfony Applications

symfony new my_project_directory

The Symfony MakerBundle

composer require –dev symfony/maker-bundle

API Platform

composer require api


composer require doctrine/annotations


composer require “lexik/jwt-authentication-bundle”

Google Provider for OAuth 2.0 Client

composer require league/oauth2-google


English Explanation of the Project


This project revolves around integrating Google Sign-In in a Symfony-based application. The primary goal is to provide users with a seamless and secure login experience using their Google accounts. To achieve this, we leveraged the thephpleague/oauth2-google package. Additionally, we utilized JWT (JSON Web Tokens) for secure and efficient user authentication, particularly in API requests.


Choice of Technology

We chose Symfony for its robust framework capabilities, offering extensive support for web application development. API Platform was selected for its ability to easily create high-performance RESTful APIs. The thephpleague/oauth2-google package was particularly useful for handling Google OAuth 2.0 authentication flows in a standardized manner.


Architectural Overview

The application architecture is designed to support RESTful API standards, primarily managed through Symfony and API Platform. This structure allows for efficient handling of HTTP requests and responses, and it seamlessly integrates with the Google authentication process.


Google Sign-In Integration

Integration of Google Sign-In was accomplished by incorporating the thephpleague/oauth2-google package into the Symfony project. This package facilitated the authentication process with Google’s OAuth 2.0 servers, allowing users to securely log in with their Google accounts. We managed the OAuth 2.0 flow, including token retrieval and validation, ensuring a secure login process.


JWT for Authentication

JWT played a crucial role in authenticating API requests. After successful Google Sign-In, users were provided with a JWT, which was used for subsequent API requests to authenticate the user. This token-based approach enhances security by ensuring that each request is verified and authenticated, minimizing the risk of unauthorized access.


Challenges and Solutions

The integration presented several challenges, particularly in aligning the Google authentication flow with the existing Symfony framework and ensuring seamless JWT handling. These were overcome through careful configuration and testing, ensuring that the authentication process was both secure and user-friendly.



The project successfully implemented Google Sign-In and JWT authentication in a Symfony application with API Platform, enhancing both the user experience and security. This implementation demonstrates the effective use of third-party authentication services and token-based authentication in modern web application development.
