Npcink Pay Refund adds a WordPress admin refund console for merchants who need to query and refund Alipay and WeChat Pay orders by payment order number.

The plugin is not a checkout gateway and does not create payments. It focuses on controlled refund operations after a payment has already been created by your existing payment flow.

Features:

  • Query Alipay and WeChat Pay orders from the WordPress admin.
  • Run full refunds for eligible paid orders.
  • Restrict refund actions to administrators and selected refund operators through a dedicated capability.
  • Store refund records in a custom WordPress database table.
  • Keep payment secrets in a separate non-autoloaded option.
  • Prevent duplicate refund submissions with order-level locking.
  • Export refund records for internal review.
  • Check local payment configuration before running live refund operations.

By default, merchant private keys and public keys are stored in the site’s WordPress database options. Keep access to administrator accounts, backups, and database exports restricted.

For deployments that keep secrets outside the database, define NPCINK_PAY_REFUND_ZFB_PRIVATE_KEY, NPCINK_PAY_REFUND_ZFB_PUBLIC_KEY, NPCINK_PAY_REFUND_WX_CERT_KEY, and NPCINK_PAY_REFUND_WX_PLATFORM_PUBLIC_KEY in wp-config.php. These constants take precedence over saved option values and are never written by the settings form.
