Use one merchant account and one API for supported VND, PHP and USDT payment flows. Payment-status changes are delivered through signed webhooks. Merchant onboarding requires KYB review, with separate sandbox and production environments.
1. Confirm scope
List the countries, currencies and pay-in or payout flows you need. Confirm enabled methods with the CVPay team before implementation.
2. Review and test
Review the current integration documentation. In sandbox, verify your payment flow and signed webhook handling before production.
3. Prepare for production
Complete merchant KYB review and confirm the supported configuration. Sandbox is separate from production; production access is not implied by visiting this page.
