How It Works

Card data is submitted directly from the browser to Authorize.Net using their Accept.js library — your Magento server never handles raw card numbers. The extension receives a payment nonce in return and uses it to complete the transaction via the Authorize.Net API. This keeps you out of PCI scope for card data handling.

The SHA-512 Signature Key replaces the deprecated MD5 hash for webhook validation, ensuring transaction notifications from Authorize.Net are authenticated correctly.

Admin Order Management

Once an order is placed, the full transaction lifecycle is available from the Magento Admin order view:

Capture a previously authorised transaction when the order ships
Void an authorisation before capture if the order is cancelled
Refund a captured transaction directly to the customer’s card from the credit memo screen
All actions are logged to the order’s transaction history with Authorize.Net transaction IDs for reconciliation

Admin Configuration

Settings are at Stores > Configuration > Sales > Payment Methods > Authorize.Net:

API Login ID and Transaction Key — from your Authorize.Net merchant account
Signature Key — required for SHA-512 webhook validation
Payment action — Authorisation Only or Authorise & Capture
Sandbox mode — test against the Authorize.Net sandbox before going live
Accepted card types — restrict which card networks appear at checkout
