Leveraging Secure and Authenticated Email Delivery in Laravel 10: A Definitive Guide with PHPMailer & Google OAuth 2.0 Integration

Introduction

CEOs and business leaders, welcome to a transformative journey into secure email delivery within the Laravel framework, a realm of unparalleled security. In this comprehensive tutorial, we’ll explore the integration of PHPMailer and Google OAuth 2.0, empowering you to enhance your email delivery capabilities and ensure utmost reliability.

Step 1: Configuring Your Google Cloud Project

Our journey begins with the creation and configuration of a Google Cloud Project. Navigate to the Google Cloud Platform, where you can either create a new project or select an existing one. Once your project is ready, take the pivotal step of enabling the Gmail API. This API lays the foundation for secure email transmission within your Laravel application.

Step 2: Crafting OAuth Consent

Next, we navigate to the OAuth Consent Screen, a crucial component in our quest for email excellence. This screen demands meticulous attention to detail, as it requires essential information such as the App Name, User Support Email, and Developer Contact Information. Follow the prompts, and as you proceed to the Summary Page, you’ll find the path back to the dashboard, where you can take the final step of publishing your OAuth App. Now just click the “PUBLISH APP” button to mark this significant milestone.

Step 3: Creating the OAuth Client ID

Now, venture into the Credentials Menu within the left sidebar. Click “CREATE CREDENTIAL” and opt for “OAuth Client ID” from the dropdown menu. Opt for “Web Application” as the Application type and assign a name to your OAuth 2.0 Client. Additionally, add Authorized Redirect URIs, which define the URL where you’ll securely obtain the token. After meticulously completing these fields, click the “CREATE” button. Don’t forget to securely store the Client ID and Client Secret; you’ll rely on them in the future.

Step 4: Configuring Your Laravel Project

Open your Laravel project within your preferred code editor (we recommend VSCode). To integrate PHPMailer and Google OAuth, you’ll need to employ Composer to install two essential libraries:

1. PHPMailer
2. Google OAuth

With these libraries at your disposal, navigate to your .env file and diligently insert the Client ID and Client Secret you secured earlier. Subsequently, proceed to configure routes and blade files, with all necessary code conveniently available in our dedicated GitHub repository. As an additional step, create routes to efficiently handle requests for obtaining and posting tokens from Google OAuth.

// Required Routes
Route::prefix('/')->group(function() {
    Route::view('home', 'home')->name('home');
    // Generate Token
    Route::post('/token', [OAuthController::class, 'doGenerateToken'])->name('generate.token');
    // Get Token
    Route::get('/token', [OAuthController::class, 'doSuccessToken'])->name('token.success');
    // Send Email
    Route::post('/send', [MailController::class, 'doSendEmail'])->name('send.email');
});
