Sales Tax Calculator API

API changes

Changelog

Customer-visible changes to the sales tax calculation API, developer console, and account controls.

v1 release candidate

The public API, dashboard, and developer contract now share one resource-oriented interface.

  • Added compact sales tax calculation, transaction, exact adjustment, batch, and coverage resources.
  • Simplified the developer console to Overview, API Keys, Logs, Usage, Billing, and Settings.
  • Moved seller, registration, location, tax-behavior, and billing-event facts into every sales tax calculation request.
  • Removed tax setup, tax-case management, team structures, specialized roles, and launch webhook controls.
  • Published one OpenAPI 3.1.2 contract with generated server-side TypeScript and client-only Python SDKs.
  • Added explicit unsupported and review-required outcomes for combinations that cannot receive a determinate result.
