# Shopify Global Catalog REST API stops serving traffic on 2026-11-02

- **Provider:** Shopify
- **Endpoint:** `* /global/v2/**`
- **Effective:** 2026-11-02
- **Severity:** critical
- **Change:** version-sunset
- **Status:** verified

## What changed

The Global Catalog REST API on discover.shopifyapps.com (/global/v2/search, /global/v2/p/{upid}, /global/v2/p/by-variant/{vid}, POST /global/v2/lookup, including saved-catalog requests) stops serving traffic on November 2, 2026, and requests to it will fail. Anything still calling it must move to the Global Catalog MCP server.

## What to do

Switch to the Global Catalog MCP server at https://catalog.shopify.com/api/ucp/mcp: use the search_catalog tool instead of GET /global/v2/search, get_product instead of the single-product and by-variant lookups, and lookup_catalog (up to 50 items per request) instead of POST /global/v2/lookup.
