Ask your app supplier whether it uses this retired API and what migration and testing have been completed.
THE SOURCED NEWS
An earlier notice reaches its stated stop date
Shopify says the change affects Global Catalog REST requests, including saved catalogs. Its replacement uses a different set of catalog tools and request and response schemas. The notice says authentication is unchanged.
The relevant dates are distinct: the announcement was published on 9 October and names 2 November as the retirement date. This explainer does not independently test a merchant’s integration or confirm the precise shutdown time.
SELLERBUNDLE PRACTICAL ANALYSIS
SellerBundle: describe the failure before replacing the tool
Write down which task fails, when it last worked and the message you see. Identify the app or service involved. Ask its supplier a focused question about this named API rather than assuming every catalog problem has the same cause.
If the supplier confirms the connection is affected, ask for the migration status, the expected restoration time and a safe temporary way to handle the task. Keep access credentials out of screenshots and public support posts.
SELLERBUNDLE PRACTICAL ANALYSIS
Check the result from a customer’s point of view
After the supplier makes a change, test a small set of products that includes different variants and availability states. Compare the information returned with the store’s own product records. Check the task that originally failed before declaring the issue resolved.
A successful login or a tool appearing connected is only part of that review. Record what was tested, the outcome and who will monitor the next normal run. Escalate a continuing mismatch with a reproducible example.
