March 5

Version: 2026.7

• Added support for sending product commodity codes and types to Vertex O Series, enabling HSN-based tax calculation for Vertex for Marketplaces.
• Added support for the BQ country code for the Caribbean Netherlands by mapping it to the Vertex country code VX4, reducing transaction errors.
• Added support for a new India Goods and Services Tax Identification Number (GSTIN) validation service that provides real-time tax ID validation, SEZ status, business name, and address across all e-commerce endpoints.
• Fixed an issue where selecting the Valid (syntax) option in the Validation Statuses field of the Tax Number Validator Report caused scheduled reports to fail.
• Fixed an issue where European Union (EU) business-to-business (B2B) transactions were not tax-exempt when the buyer’s tax number was provided in the buyer-tax-numbers field.
• Updated the Italian domestic CAPTCHA provider to use syntax-check validation by default, while still allowing EU-level settings to override this behavior when configured.
• Updated the dashboard to record which user changed a merchant setting, improving audit visibility for configuration changes.
