Starting with API version 2026-01, third-party tax applications will receive Global IDs (GIDs) instead of legacy ID formats in tax calculation requests and tax summary webhook payloads. This update applies to all entity references within the summary section, standardizing how tax apps interact with Shopify's platform. Previously, tax-specific integrations required developers to manage multiple ID formats across different endpoints.
This change eliminates friction for Shopify developers building tax integrations. By adopting Global IDs across all tax endpoints, developers can now use consistent identifiers when working with other Shopify APIs—no more context-switching between different ID systems. This alignment with broader Shopify API practices reduces complexity, minimizes errors, and accelerates development cycles for partners managing multiple integrations.
If your tax app requires OAuth authentication to access Shopify's APIs, GetShopifyToken simplifies token generation and management. Our platform streamlines the process of obtaining and managing access credentials, so you can focus on implementing Global ID support and other core functionality.
