KristinaPay Gateway for Authorize.Net

KristinaPay Gateway connects your WooCommerce store to Authorize.net so you can accept credit card payments. The free version charges the customer’s card immediately at checkout, just like any standard payment gateway — with one advantage most free plugins don’t offer: a persistent, always-on transaction log so you can see exactly what happened on every checkout attempt.

If you sell custom, made-to-order, or high-value products where you don’t want to charge the customer until you’re ready to ship, see the Pro version below — it adds a verify-now, charge-later workflow with a secure card vault.

Core Features (Free)

• Full Authorize.net gateway — registers as a WooCommerce payment method, supports all standard card types
• Immediate charge at checkout — customer’s card is charged right away, standard e-commerce flow
• Persistent transaction log — every checkout event and API response logged and viewable in WooCommerce admin, with one-click JSON download. Makes it far easier to diagnose declined transactions or get support from Authorize.net.
• Sandbox / live toggle — full sandbox support for testing
• HPOS compatible — fully supports WooCommerce High Performance Order Storage
• Blocks compatible — works with the WooCommerce checkout block

Pro Features

• CIM card vault — stores cards securely in Authorize.net’s Customer Information Manager, never on your server
• Auth-only checkout — validate the card with a $1 authorization at checkout; no charge until you decide to capture
• Manual capture button — one-click capture from the order admin sidebar, whenever you’re ready to ship
• Automatic void on cancel — cancelling an on-hold order automatically voids the authorization in Authorize.net
• Refund support — process refunds directly from the WooCommerce order screen
• WooCommerce Subscriptions support — automatic recurring payments charged to the stored CIM profile on each billing date
• Multi-card vault — customers can save multiple cards and choose which to use at checkout
• My Account card management — customers can view and delete saved cards from their account
• Priority support — direct email support with 24-hour response

Getting Your Authorize.net Credentials

1. Log into your Authorize.net account

The Public Client Key is required for the Accept.js tokenization that keeps card data off your server.

Privacy

This plugin logs checkout events and API responses (order data, IP addresses, transaction status) to your WordPress database for debugging purposes. Logs are stored for 30 days and are visible only to site administrators via WooCommerce → Auth.net Logs. This plugin does not store credit card numbers; card data is tokenized directly in the customer’s browser via Authorize.net’s Accept.js and sent to Authorize.net, not to your server. Payment processing itself is handled by Authorize.net, a service of CyberSource Corporation (a Visa Inc. company) — see their privacy policy at https://www.authorize.net/company/privacy/ for how they handle payment data.

External services

This plugin connects to the Authorize.net payment API to process credit card transactions. This is required for the plugin’s core function — accepting credit card payments through WooCommerce.

Card details are tokenized in the customer’s browser via Authorize.net’s Accept.js library before submission, so raw card numbers never pass through your server. What is sent from your server to Authorize.net’s API: the payment token/nonce generated by Accept.js, the order total, and order metadata needed to process the transaction (such as an invoice/order number). This happens whenever a customer completes checkout using this gateway.
