Nimiq Checkout for WooCommerce


A plugin for WordPress WooCommerce to handle payments in the Nimiq (NIM) cryptocurrency.

Features include:

  • Automatic currency conversion from supported store currencies to NIM during checkout
  • Automatic transaction validation and WooCommerce order status updates
  • Configurable conversion and validation service providers
  • Configurable confirmation times with sane defaults
  • Includes the NIM currency for WooCommerce

Automatic Currency Conversion

This plugin can automatically convert from your store currency to NIM during checkout. Here is a list of supported currencies for the included conversion services:

Order Status Updates

After an order is submitted using the Nimiq payment method, the order is placed “on-hold”. Transactions are validated automatically on a short interval, and can also be validated manually with a Validate Transactions bulk action from the Orders admin page. When a transaction is validated, the order status changes to “processing”.


Adding A New Validation Service

Validation services are defined under ./validation_services/. Each service class must implement the WC_Gateway_Nimiq_Service_Interface, defined in ./validation_services/interface.php. The easiest way to start is to take an existing service (e.g. nimiq_watch.php) and rename and adapt it to the new service. The new service then also needs to be registered in the validation_service setting. The value of the setting must match the file name (without the .php extension) of the service definition. If the new service requires additional setting fields, settings.js also needs to be adapted to show/hide those fields conditionally.


This Nimiq gateway is based on skyverge’s WooCommerce Offline Gateway, which in turn forks the WooCommerce core “Cheque” payment gateway.
