Install Seamless Chex on WooCommerce

I simply need Seamless Chex added to my live WooCommerce store so customers can start checking out right away. The plugin (or API) is already chosen; no extra custom features are required—just a clean, standard installation on my existing business site.

Once it’s connected, please run a quick test transaction and show me where to view successful payments in the WooCommerce dashboard. That’s all I’m after, and I’m told it should be a ten-minute task for someone familiar with WordPress, WooCommerce, and basic payment-gateway setup.
