Security and compliance

Review
  • Use hosted checkout or provider tokenization to reduce PCI scope; never store raw PAN, CVV, PIN, or sensitive authentication data.
  • Support 3DS where available for card-not-present flows and expose 3DS outcome in the payment timeline.
  • Verify provider signatures/encryption before updating payment status; use JWE/JWS-compatible processing where required by the provider API.
  • Sign WQN merchant webhooks with HMAC SHA-256, timestamp tolerance, replay protection, and request IDs.
  • Keep provider credentials in a vault reference and require approval before enabling production routing.
