Carts

Connect your store

Install a cart plugin, paste Mr Ivory APP_ID + secret, and shoppers pay on hosted checkout. You do not wire an assigned card processor inside WooCommerce or Shopify. Processor keys stay in Mr Ivory.

Plugins never collect PAN or CVV. HASH is SHA-512 as on HASH. This host is a sandbox — not live acquiring and not PCI Level 1.

Install WooCommerce plugin Connect processor Try a sandbox payment

Pick a processor in Mr Ivory and paste that account’s keys.
Paste only APP_ID, secret, and the gateway origin in the cart.
Go live — shoppers pay on hosted checkout. The cart never holds a card.

WooCommerce

Copy plugins/woocommerce/mrivory-payments/ into wp-content/plugins/.
Activate Mr Ivory Payments.
WooCommerce → Settings → Payments → Mr Ivory: your APP_ID, secret, gateway URL.
Place a test order. The plugin auto-POSTs to hosted checkout. Seeded demo merchant APP_ID is 1000221129001154 (sandbox@mrivory.test).

Shopify

Practical sandbox path: a redirect app, not a Shopify Payments certified provider.

Create a custom / draft app in the Shopify partner dashboard.
Run node plugins/shopify/app/server.js with MRIVORY_APP_ID, MRIVORY_SECRET, MRIVORY_GATEWAY.
Point checkout (custom payment extension or a button) at /start.
/start signs HASH and auto-POSTs to hosted pay. /return receives STATUS only.
