U.CASH Pay for CS-Cart

Accept crypto and card payments in your CS-Cart (or CS-Cart Multi-Vendor) store through U.CASH Pay. Buyers pay at the hosted U.CASH Pay checkout; paid orders are confirmed automatically with no manual reconciliation.

How it works

1. Buyer places an order and selects U.CASH Pay.
2. CS-Cart calls the addon controller (mode=redirect), which uses the SDK to create a U.CASH Pay transaction and redirect the buyer to the hosted checkout.
3. After paying, the buyer is sent back to the store receipt (mode=return).
4. U.CASH Pay sends an HMAC-signed settlement webhook to mode=webhook. The plugin verifies the signature, reconciles amount and currency, and flips the order to Complete.

Requirements

• CS-Cart 4.x (or Multi-Vendor) running on HTTPS.
• PHP 7.2+ with the curl extension.
• A free U.CASH Pay account.

Install

1. Copy the app/addons/ucash/ directory into your CS-Cart install at app/addons/ucash/.
2. In the CS-Cart admin, go to Add-ons -> Manage add-ons and click Install on U.CASH Pay.
3. Go to Administration -> Payment methods, add a new payment method, and set its processor to U.CASH Pay.

Configure

1. In U.CASH Pay -> Account -> Stores, create a store for this CS-CCart install and copy its Cloud token and Webhook secret.

2. In CS-CCart -> Add-ons -> U.CASH Pay, paste them into Cloud token and Webhook secret, then set the U.CASH Pay URL (default https://pay.u.cash).

3. Set the store's Webhook URL (from U.CASH Pay -> Account -> Stores -> [your store] -> Edit) to:

   https://YOUR-STORE/index.php?dispatch=payment_notification.webhook&payment=ucash
   

   (Some CS-Cart installs use the SEO-friendly equivalent https://YOUR-STORE/ucash/webhook; both routes hit the same controller mode=webhook.)

4. Save, then place a test order.
