The Toweringmedia Authorize.Net extension adds secure Authorize.Net card processing to Magento 2, with strong compatibility for React Checkout Pro storefronts.

Key goals:

• Accept card payments through Authorize.Net in Magento 2 checkout.
• Support production-ready gateway setup for both testing and live traffic.
• Keep checkout behavior consistent with Toweringmedia React Checkout Pro and related payment/checkout modules.

• Connects Magento to Authorize.Net gateway credentials.
• Supports tokenized card payment flows through Magento checkout.
• Supports Accept.js, Accept Hosted, and saved card (CIM) flows.
• Supports refund/void operations and webhook signature validation.
• Enables controlled testing in sandbox before production cutover.
• Works as a core payment module in broader Toweringmedia checkout stacks.

Install via Composer (example):

cd /path/to/magento
composer require toweringmedia/module-authorizenet:<VERSION>
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

After install, confirm module status:

php bin/magento module:status Toweringmedia_Authorizenet

Go to: Stores > Configuration > Sales > Payment Methods > Authorize.Net (Toweringmedia)

Configure in this order:

1. Enable the payment method.
2. Set appropriate title and payment action.
3. Enter API Login ID and Transaction Key (or equivalent credentials used by your account setup).
4. Enable sandbox/test mode for validation first.
5. Save config and flush cache.

• Keep sandbox enabled until end-to-end checkout tests pass.
• Use a clear payment method title so support/admin teams can identify transactions easily.
• Restrict to applicable countries/payment contexts as needed.
• Keep logging at safe levels in production (avoid exposing sensitive request details).
• Keep API keys, signature keys, and wallet cert material outside webroot and outside Git.

This module is commonly used with:

• Magento 2 React Checkout Pro Extension
• Magento 2 React Checkout Pro Express Extension

If payment options are grouped in React Checkout Pro, ensure the Authorize.Net payment code is in the expected primary/visible group.

• Module is enabled in Magento and appears in module status.
• Admin payment configuration is accessible at correct scope.
• Sandbox transaction can be authorized successfully.
• Production transaction works after credential switch.
• Order placement, invoice capture/refund flow, and order history records are correct.
• No critical payment errors in logs during checkout attempts.

• Method not visible at checkout: Check method enabled state, store scope, country restrictions, and checkout payment grouping.
• Gateway credential error: Re-validate API Login ID/Transaction Key and sandbox/live mode alignment.
• Order submit fails: Confirm payment action compatibility, merchant account state, and any CSP/browser console errors.
• React checkout mismatch: Re-check React Checkout Pro payment layout/group config and cache state.
