PaymentDash Gateway for NMI

PaymentDash lets your WooCommerce store accept credit and debit cards through your own NMI merchant account, directly or through an NMI-powered provider.

Card numbers are typed into NMI’s secure card fields (Collect.js), which NMI hosts. They go straight from your customer’s browser to NMI and never touch your website, which keeps your PCI scope small.

Features

• Card payments on the block checkout and the classic checkout, plus the order-pay page
• Charge right away, or authorize only and charge when you mark the order Processing or Completed (or from the order actions)
• Refunds from the WooCommerce order screen, full or partial. A full refund of a payment that has not settled yet is sent as a void, so the customer is never charged.
• Test mode for NMI sandbox accounts
• NMI payments screen (WooCommerce → NMI payments) with card totals for today, the last 7 days and the last 30 days, and your latest payments
• Billing and shipping details sent to NMI for address checks and receipts
• Optional debug log in WooCommerce → Status → Logs. Keys and card details are never logged
• Works with WooCommerce order storage (HPOS)

External services

This plugin connects to NMI (Network Merchants, LLC), the payment gateway that processes your card payments. It cannot work without it.

• What is sent and when: On the checkout and order-pay pages, your customer’s browser loads NMI’s Collect.js script from secure.nmi.com (or sandbox.nmi.com in test mode). The card number, expiry date and security code typed into the card fields are sent by that script directly to NMI, which returns a one-time token. When the order is placed, your website sends that token to NMI’s Payment API (https://secure.nmi.com/api/transact.php, or https://sandbox.nmi.com/api/transact.php in test mode) together with the order amount, tax and shipping amounts, currency, order number and description, the customer’s billing name, company, address, email and phone number, their shipping name and address, and their IP address. Captures, refunds and voids send the NMI transaction ID, the amount and, for voids, a reason code.

The plugin does not send any data to PaymentDash or anyone else. Links to the PaymentDash website in the admin screens are ordinary links that open only when you click them.
