Shopify scheduled Global Catalog REST API retirement for November 2. The notice was published on October 9; this is not a new announcement today. Businesses with custom product search using this API should obtain migration confirmation from their developer.
What the change covers
Shopify says old requests will stop working after retirement, including saved catalogs. The replacement is Global Catalog MCP. The source gives no exact shutdown time or timezone; Nadali has not verified that service has actually stopped.
The replacement documentation describes AI-agent product discovery across multiple merchants. It directs single-store use to Storefront Catalog MCP. Therefore, the Shopify name alone does not establish that a particular integration depends on the old API.
What to ask your contractor for
Nadali’s editorial recommendation is to request a short verification record rather than a general “everything migrated”:
- The function that used the old catalog and the person responsible for it.
- Agreed test queries and their actual results after migration.
- A check of product and variant selection, not merely a successful connection.
- A clear procedure for staff when results are empty or a request fails.
An illustrative example: for a size-specific search, the team compares the selected variant with the task. This is a proposed scenario, not a real store test result.
Takeaway: confirm the dependency and migration result before declaring the issue resolved. This reports an announced deadline, not an observed widespread outage or a new AI launch. Nadali has not tested accounts, integrations or sales effects.
