Compared with V2, V3 introduces systematic improvements in architecture design, interface standards, and system performance, further enhancing stability, scalability, and enterprise-level integration experience.

Key Enhancements in V3

  • Simplified authentication (API Key only; no secret key required)

  • Optimized Risk Engine architecture and performance

  • Standardized response structures and field naming conventions

  • Improved API consistency and extensibility

  • Clearer version governance and long-term maintenance strategy

V3 retains the core risk control capabilities available in V2 while upgrading the underlying implementation and interface specifications, delivering a more structured, stable, and efficient integration experience.

We strongly recommend that all new integrations adopt V3. For existing V2 users, migration planning is highly encouraged to ensure continued access to feature updates and long-term technical support.

Important Notice: V2 will be officially deprecated and will no longer be maintained after December 30, 2026.
