- Shopify will stop setting the _landing_page, _orig_referrer, and _tracking_consent cookies on merchant storefronts as of September 15 2025.
- Code that reads these cookies must be updated to use documented APIs (Web Pixels API, Customer Privacy API, or GraphQL Admin API) to obtain landing page, referrer, and consent data.
- Developers should switch to browser APIs (window.location.href, document.referrer) or the provided GraphQL queries for session tracking.
