The QFPay OpenAPI is accessible through three environments: Production, Live Testing, and Sandbox. Each environment serves a different purpose and uses a distinct base URL. Always ensure you are targeting the correct environment during development and deployment.

​
Environment Overview

EnvironmentBase URLPurpose
Productionhttps://openapi-hk.qfapi.comLive payments with real settlement
Live Testinghttps://test-openapi-hk.qfapi.comReal payment flow using test accounts (no settlement)
Sandboxhttps://openapi-int.qfapi.comSimulated transactions for development and testing

​
When to use each environment

​
Sandbox

Use Sandbox for:
  • initial development
  • testing API connectivity and signatures
  • simulating credit card transactions
  • verifying request/response handling
Sandbox transactions do not deduct real funds.
Sandbox may not support all payment methods.

​
Live Testing

Use Live Testing for:
  • validating real payment flows
  • testing QR code and wallet payments
  • end-to-end testing before production launch
Transactions performed using test accounts will not be settled.If real payment methods are used during testing, ensure refunds are processed immediately.

​
Production

Use Production when:
  • integration is fully tested
  • you are ready to accept real payments
  • settlement and reconciliation are required

​
Important Notes

Using credentials or endpoints from a different environment will result in authentication or signature errors.
Always confirm with QFPay which environment and credentials should be used for your deployment.
  1. Develop and test in Sandbox
  2. Validate payment flow in Live Testing
  3. Deploy to Production
