PayMoney.online Payment Gateway for OpenCart 4​

Accept online payments on your OpenCart store via PayMoney.online. Customers are redirected to a secure hosted checkout, pay, and return to your store — while the order is confirmed server-to-server through a signed IPN (webhook). The extension is self-contained (everything lives in extension/paymoney/) and installs through the built-in OpenCart Installer, so no core files are changed.


Compatibility: OpenCart 4.0.2.0 – 4.1.x · PHP 8.0+ (cURL & OpenSSL)


Key features

• Hosted checkout — customers pay on the secure PayMoney.online page
• HMAC-SHA256 signed API requests for every call
• Secure IPN (webhook) confirmation with signature verification — the authoritative source of payment status
• Amount & currency cross-check and idempotent order updates
• Sandbox and Production environments with environment-aware credentials
• One-click "Test Connection" button in the admin to validate credentials before going live
• Configurable order statuses (Completed / Pending / Failed), geo zone and sort order
• Bilingual admin & storefront: English and Russian
• Installs via OCMOD .ocmod.zip — no core edits

Requirements

• OpenCart 4.0.2.0 – 4.1.x
• PHP 8.0+ with cURL and OpenSSL
• Valid SSL certificate
• A PayMoney.online merchant account (Merchant ID, API Key, API Secret Key)

Installation (about 3 minutes)

1. Download the extension (paymoney.ocmod.zip).
2. In the admin go to Extensions → Installer, upload the ZIP, then click the green Install button to extract the files.
3. Go to Extensions → Extensions, choose type Payments, find PayMoney.online and click Install, then Edit.
4. On the API Credentials tab enter your Merchant ID, API Key and API Secret Key for the selected environment, then press Test Connection.
5. Set Environment = Sandbox, place a test order and pay with the demo wallet to verify checkout and IPN.
6. Switch to Production with live keys (after merchant approval) to accept real payments.

Notes

• The order currency must be enabled for your merchant and backed by an active wallet.
• Which gateways appear on the checkout page is controlled on the merchant side (Merchant → Config → Payment Gateway Controls).
• Production API access becomes available after merchant approval — test in Sandbox until then.
