Buy something, then refund yourself.
A real WooCommerce store wired to a sandbox NMI gateway, with the admin open. Place an order, look at what lands on the order screen, then capture, refund or void it yourself.
Sandbox credentials, no real money moves. The store resets every hour.
The demo store
A three product shop with a subscription, a high ticket item for ACH, and a normal one off product.

Standard NMI sandbox values. Any future expiry works unless you want to see a decline.

Forcing a decline by amount
The sandbox declines specific totals so you can see the error path. Try an order ending in .05 for a hard decline, and .10 for a processor timeout. The checkout should tell the buyer what to do next, not print a gateway code at them.
The admin side
Read only demo account. Some destructive actions are disabled, everything else is live.
- Place an order with a test cardWatch the card fields load from the gateway rather than from the page, then check the order note for the auth code and AVS result.
- Capture a partial amountOpen the order, capture less than the authorized total, and see both WooCommerce and the gateway record stay in step.
- Refund and voidRefund part of a captured order, then void an uncaptured one, and compare what the customer would see on a statement.
- Save a card, then reorderTick save at checkout, look at My Account, then buy again with the stored token and no card entry.
- Buy the subscription productThen trigger a renewal from the subscription screen to see a scheduled charge run against the vault token.
- Read the logOpen the gateway log and confirm the card number and security key are not in it.
