Setting Up Authorize.Net Laravel Integration: A Step-by-Step Guide

Are you looking to integrate a secure and reliable payment gateway into your Laravel app? Then Authorize.Net Laravel integration is a perfect solution. In this guide, we’ll take you through the steps to set up Authorize.Net in your Laravel project.

Why Choose Authorize.Net Laravel Integration?

First and foremost, Authorize.Net is a trusted name in online payments. It allows businesses to accept credit card and e-check payments easily. Moreover, Laravel makes integration simple thanks to its flexible architecture. That’s why Authorize.Net Laravel integration is highly recommended for modern developers.

Step 1: Create an Authorize.Net Account

Before anything else, sign up at Authorize.Net’s Developer Center. You’ll need a sandbox account for testing. This sandbox account gives you the API Login ID and Transaction Key you’ll use later. These credentials are essential for Authorize.Net Laravel integration.

Step 2: Install Laravel and Set Up the Project

Next, if you haven’t already, install Laravel by running:

composer create-project laravel/laravel authorize-net-laravel

Once the Laravel app is ready, navigate into your project directory. This forms the foundation for your integration project.

Step 3: Install Authorize.Net SDK

Laravel doesn’t include Authorize.Net support by default. Therefore, install the SDK via Composer:

composer require authorizenet/authorizenet

This SDK lets you send payment requests, process transactions, and more—all essential features of your integration.

Step 4: Set Environment Variables

In your .env file, add your API credentials:

AUTHORIZE_NET_API_LOGIN_ID=your_login_id
AUTHORIZE_NET_TRANSACTION_KEY=your_transaction_key

These keys are required for authenticating your requests during the integration process.

Step 5: Create a Payment Controller In Authorize.Net Laravel Integration

Generate a controller to handle the payment logic:

php artisan make:controller PaymentController

Now, inside PaymentController.php, add the payment function using Authorize.Net SDK. This function will handle the core logic of Authorize.Net Laravel integration.

Step 6: Implement the Payment Logic In Authorize.Net Laravel integration

Here’s a simplified version of how to create a transaction:

use net\authorize\api\contract\v1 as Anet;
use net\authorize\api\controller as AnetController;

public function makePayment(Request $request) {
    $merchantAuthentication = new Anet\MerchantAuthenticationType();
    $merchantAuthentication->setName(env('AUTHORIZE_NET_API_LOGIN_ID'));
    $merchantAuthentication->setTransactionKey(env('AUTHORIZE_NET_TRANSACTION_KEY'));

    $creditCard = new Anet\CreditCardType();
    $creditCard->setCardNumber("4111111111111111");
    $creditCard->setExpirationDate("2025-12");

    $paymentOne = new Anet\PaymentType();
    $paymentOne->setCreditCard($creditCard);

    $transactionRequestType = new Anet\TransactionRequestType();
    $transactionRequestType->setTransactionType("authCaptureTransaction");
    $transactionRequestType->setAmount(20.00);
    $transactionRequestType->setPayment($paymentOne);

    $request = new Anet\CreateTransactionRequest();
    $request->setMerchantAuthentication($merchantAuthentication);
    $request->setTransactionRequest($transactionRequestType);

    $controller = new AnetController\CreateTransactionController($request);
    $response = $controller->executeWithApiResponse(\net\authorize\api\constants\ANetEnvironment::SANDBOX);

    if ($response != null) {
        if ($response->getMessages()->getResultCode() == "Ok") {
            return response()->json(['message' => 'Transaction successful']);
        } else {
            return response()->json(['message' => 'Transaction failed']);
        }
    } else {
        return response()->json(['message' => 'No response returned']);
    }
}

This logic is essential in the integration and helps process real transactions securely.

Step 7: Set Up Routes

In your web.php, add the route to handle payments:

Route::post('/pay', [PaymentController::class, 'makePayment']);

This route connects your front-end form to your back-end logic, making the integration functional.

Step 8: Create a Payment Form

Now, create a simple Blade view for your form:

<form action="/pay" method="POST">
    @csrf
    <input type="text" name="card_number" placeholder="Card Number" />
    <input type="text" name="exp_date" placeholder="MM/YYYY" />
    <button type="submit">Pay</button>
</form>

This form is where users input payment details. It connects directly to your integration backend.

Step 9: Test the Payment Flow

Using the sandbox, test the flow from the form submission to payment success. This is crucial for verifying that your integration works end-to-end.

Step 10: Go Live

Finally, switch your credentials from sandbox to live. Update the environment and test again. Your integration is now complete and production ready.

Conclusion: Smooth Payments with Authorize.Net Laravel Integration

In conclusion, the integration is straightforward when broken into steps. From setting up credentials to writing controller logic, each task contributes to a seamless payment process.

Furthermore, Laravel’s flexibility and Authorize.Net’s powerful SDK make integration smooth and secure. Whether you’re a solo developer or part of a large team, it will elevate your application’s capabilities.

So, take the time to implement it right. As a result, you’ll provide your users with a seamless and reliable payment experience.
