What is Partner Certification?

A streamlined validation process that helps ensure your integration with Kintsugi provides the best experience for our mutual customers.
Your path from build to badge: we validate together, you ship with confidence.

​
Why Get Certified?

​

​
For Mutual Customers

​
What Certification Means

Being Kintsugi Certified means your integration has passed our validation and is ready for production:
  • ✅ Tax calculations are accurate across all supported jurisdictions
  • ✅ Transaction syncing works reliably for orders, refunds, and lifecycle events
  • ✅ Error handling gracefully manages edge cases and API responses
  • ✅ Address validation provides clear, actionable feedback to users
Certification is binary: you’re either Kintsugi Certified or not. No tiers, no levels—just a clear validation that your integration meets our quality standards.

​
Who Should Get Certified?

​
Integration Patterns

Kintsugi may be able to meet you half way, and build the transaction sync aspect of the integration for you. In these cases, you would only need to build the “L2”, or tax calculation flow. In other cases, partners would need to build the integration end-to-end.

​
L1: Transaction Sync

  • Kintsugi or Partner builds and maintains the transaction sync integration
  • Certification required if partner-built.
  • We provide guidance and validate functionality, if Partner-built

​
L2: Partner-Built Integrations

  • Partner builds and maintains the tax estimate integration
  • 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

​
Support Throughout the Process

Our Solutions Engineering team guides you through every step:
  • Technical implementation support
  • API question responses
  • Validation testing coordination
