Integration Patterns

Kintsugi uses a two-level integration model. Level 1 (L1) is transaction sync—the foundation. Level 2 (L2) adds the tax engine (real-time tax calculation at checkout). L1 must be in place before L2 can be enabled. Kintsugi may build the transaction sync (L1) aspect of the integration for you. In those cases, you would only need to build the L2 tax calculation flow. In other cases, partners build the integration end-to-end.

​
L1: Transaction Sync (Level 1)

  • Kintsugi or Partner builds and maintains the transaction sync integration
  • Syncs completed transactions for compliance tracking and nexus determination
  • Certification required if partner-built
  • We provide guidance and validate functionality if partner-built

​
L2: Tax Engine (Level 2)

  • Partner builds and maintains the tax estimate integration (or enables it on an existing L1 connection)
  • Adds real-time tax calculation during checkout; transaction sync (L1) continues for compliance
  • Certification required
  • We provide guidance and validate functionality

​
Hybrid: L1 Base + L2 Extensions

  • Kintsugi or Partner builds core integration (L1)
  • Partner extends with additional features (L2)
  • Certification required for partner-built components
