Quick answer
OpenCart: enable only a maintained payment integration for the intended merchant account and currency. Test with the provider's protected sandbox before live charging.
Applies to
For a customer who operates their own OpenCart store. The retained video uses an older release. Current releases, required extensions and menus can differ. Hosting compatibility, licenses, merchant services and store-development support require their own confirmation; none is automatically included merely because cPanel is available.
Steps
- Confirm the installed OpenCart version, authorized store administrator and exact store/language scope. Preserve a recovery copy and use a protected test store for changes affecting transactions.
- Open Extensions, with the Payments extension type, review the integration's current requirements and connect through its supported secure flow. Keep live/test credentials distinct and review callback/webhook requirements.
- Save only the intended change and verify the actual storefront and relevant business records before releasing it to customers.
Check the result
Verify a sandbox success, failure and relevant refund/status transition. Check the actual provider transaction rather than treating a store status as proof of payment.
Troubleshooting and support
For a pending order or declined payment, retain redacted provider references and inspect gateway logs. Do not put card data, secret keys or complete callbacks into public support material.
Contact support from the owning account with the domain, product/version, exact error, time/time zone and redacted evidence. Exclude credentials, session URLs, payment details and private customer records. Confirm any separate application-support scope.
