README

Card payments through Authorize.Net for Zero Checkout (zero_authorizenet). Accept.js turns the card fields into a short-lived token in the browser; the charge (authCaptureTransaction) is made on the server when the order is placed, for the order's base grand total. Uses the official authorizenet/authorizenet SDK.

Settings: Stores > Configuration > Sales > Payment Methods > Credit Card (Authorize.Net): Enabled, Title, Test Mode, the sandbox and live API Login ID, Transaction Key and Client Key.

Install

Requires Magento Open Source 2.4.7–2.4.9 and PHP 8.2–8.4 with the GD extension built with WebP (php -r 'var_dump(function_exists("imagewebp"));' says true; Magento's own PHP requirements cover the rest). Without WebP in GD, Zero skips its WebP image copies and serves the originals.

composer require zerofront/module-zero-authorize-net
bin/magento setup:upgrade
bin/magento setup:di:compile           # production mode
bin/magento setup:static-content:deploy # production mode
bin/magento cache:flush

Composer installs zerofront/module-zero-checkout with it.

Part of zerofront/zero, which installs the Zero theme and every Zero module at once.

What the answer does to the order

The transaction's responseCode:

Code	Meaning	The order
1	Approved	Paid and invoiced
4	Held for review (Fraud Detection Suite filters)	Payment Review, status Suspected Fraud, the invoice open; additional information `authnet_held_for_review` = 1
2, 3, other	Declined, error	Refused: the customer sees Authorize.Net's reason and no order is made

An error on the transaction response refuses the order whatever the code.

Payment Review. On the order, Accept Payment approves the held transaction on Authorize.Net (updateHeldTransactionRequest, action approve) and Magento pays the invoice; Deny Payment declines it (decline) and Magento cancels the invoice and the order. When Authorize.Net refuses either, the admin sees its message and the order stays in review. Authorize.Net only holds transactions when a fraud filter in the merchant interface is set to "hold for review", so a store without those filters never sees this.

Refunds

Credit memos refund the card (refundTransaction, by the card's last four digits). A payment Authorize.Net hasn't settled yet (it settles daily) can only be voided whole, so a partial refund is refused until it settles.

Not confirmed in a sandbox

Response codes 1-4 and code 4 arriving without errors are from Authorize.Net's API reference; Accept and Deny of a held transaction need a sandbox with a fraud filter on "hold for review" and have not been run against Authorize.Net yet.
