Dates that matter
Each date is labeled with where it comes from. Black Friday is the calendar. The others are Shopify's.
· Global Catalog REST API stops
The deprecated Global Catalog REST API stops serving traffic. Only matters if an app still calls it.
· Black Friday
The calendar date for Black Friday 2026. Not a Shopify product launch.
Calendar
· Old Shop Promise claims end
Last day a customer can claim the previous $5 Shop Cash credit on an order placed before the store moved to the updated Shop Promise program.
· Expiring offline tokens
Public apps still using non-expiring offline tokens are delisted and blocked from new installs. Existing installs can keep calling the affected APIs until April 1, 2027.
· Admin warning, and the old knowledge base app ends
Merchants using a public app that missed the token migration see a warning in the admin. The same day, the standalone Knowledge Base app is no longer available. Stores with more than 1,000 facts in that app need to add the ones they want before then.
