Two currencies.
No guesswork.

Your customer chooses a currency. The matching merchant link does the rest. No silent currency switch, no fallback to somebody else’s account.

Know what happens
behind the checkout.

Test mode is a simulation. Live payments use a separate provider flow, with their own setup and verification requirements.

A scan is progress, not proof of payment. A return page is not a receipt. The integration keeps those differences visible.

Understand payment evidence

A few things worth knowing.

Is KH Payment a bank or payment network?

No. It is independent integration software. Payment processing remains with the configured provider. It is not an ABA Bank website, official PayWay plugin or KHQR operator.

Do KHR and USD use the same merchant link?

No. Each currency uses its own merchant-owned link. Configure either currency or both. A missing USD link never falls back to a KHR link.

Does scanning a QR confirm payment?

No. Scanning and returning to a page are not proof of payment. Status evidence must come from the transaction-bound provider flow, and public-link evidence is not official settlement verification.

Can I test without making a payment?

The self-service release is designed around a clearly labeled simulator. It is separate from the existing operator’s real provider testing. This public example never contacts a bank or creates a payment.
