OpenPath Woo 3.9.2 for WooCommerce

Release date: September 2, 2026

Version 3.9.2 improves duplicate-payment handling, checkout feedback, and gateway presentation for the OpenPath Legacy WooCommerce payment gateway.

What changed

Refined duplicate-transaction and idempotency handling to better prevent accidental repeat charges while allowing shoppers to retry confirmed declines promptly.
Added a configurable Duplicate protection window (minutes) in the gateway settings. It defaults to 30 minutes and supports values from 1 to 1,440 minutes. We recommend keeping the setting at the default 30 minutes with this release.
Improved payment-decline messages in both classic checkout and Cart/Checkout Blocks. Shoppers now see a clear reason for a decline rather than a generic error, while full processor details remain available in the WooCommerce order note for support.
Added a checkout layout safeguard so AJAX decline notices display correctly in themes using two-column grid layouts.
Added the OpenPath “O” icon in WooCommerce administration and payment-method configuration. The icon remains hidden at checkout to avoid oversized rendering in certain themes.

Card-number validation update

Luhn checksum validation has always been available through the OpenPath back office and Transaction API. Version 3.9.2 removes the redundant WooCommerce-side Luhn check, so validation is managed centrally rather than in two places.

The back-office setting can be enabled or disabled through backend API configuration. This platform-independent approach supports processors, issuers, and test-card scenarios that use valid card numbers which do not follow the Luhn checksum.

WooCommerce continues to enforce basic card-entry requirements, including numeric input and valid card-number length.
