Integrate Authorize.net Payment Gateway In Laravel 12
Accepting payments on your Laravel application can be overwhelming when you're dealing with third-party gateways. Most tutorials push you toward installing packages—but what if you want full control with no extra baggage?
In this guide, I’ll walk you through integrating the Authorize.Net payment gateway in Laravel 12without using any package, focusing on test mode to keep things safe for development. You’ll learn how to:
Build a Bootstrap-powered payment form
Send transactions directly to Authorize.Net
Validate payment responses
Securely verify webhooks from Authorize.Net
Let’s dive right in.
🧠 Why No Package?
Laravel has great community packages for payments, but they often come with extra layers of abstraction. When working with a gateway like Authorize.Net that has a detailed and well-documented API, doing it "barehanded" gives you:
Full control of request structure
Better debugging and logging
No dependency on package updates
Easier compliance with specific API versions
🛠️ Prerequisites
Before you start, make sure you have the following:
Laravel 12 installed
An Authorize.Net sandbox account: https://developer.authorize.net/hello_world/sandbox.html
Sandbox API Login ID, Transaction Key, and Signature Key
Visit /payment in your browser to view the payment form.
🌐 Step 4: Testing the integration
Run the below command
php artisan route:cache
php artisan serve
after running the above URL you can open the below URL
localhost:8000/payment
When you visit this URL, you have the UI like the one below
When click on the pay now payment being received by the authorize.net and you will receive email as for the payment like the one below
🧪 Test Card Details
Use the following test card to simulate payments in Authorize.Net sandbox:
Card Number: 4111 1111 1111 1111
Expiration Date: Any future date
CVV: Any 3 digits
Amount: Any amount, like 10.00
🔒 Webhook Security
When Authorize.Net sends webhooks (like transaction status updates), you must verify the HMAC signature using your Signature Key. Laravel makes this easy by:
Reading the X-ANET-SIGNATURE header
Computing HMAC with the request body
Comparing them securely
Pro tip: Log these payloads first in development. Webhooks may contain important data you’ll want to store later.
✅ Benefits of This Approach
You understand every line of logic
No third-party abstraction
Easy debugging via dd() or Log::info()
Readily extendable for subscriptions, refunds, etc.
👨💻 Final Thoughts
Integrating Authorize.Net without a package in Laravel might look a little intimidating, but it’s really just about structuring your JSON payload properly and securing your credentials. Once you get past the first successful payment, the rest becomes straightforward.
Whether you’re building a SaaS platform, eCommerce site, or a donation portal, this method gives you the confidence that your payment logic is truly yours.
