I´ve got the same issue. When will this be fixed?
Topic summary
Headless storefront checkouts are intermittently 302-redirecting from API-provided checkout URLs back to the storefront, triggering the password page or /checkouts/co/:id/stock-problems, despite valid inventory.
Key details
- Affects stores using Shopify Buy SDK/Storefront API. Checkout URL is rewritten to /checkouts/co/{id}, then blocked by storefront password.
- Began recently; some stores unaffected or only affected intermittently. Mobile occurrences reported. Geo variance noted (e.g., Denmark vs. North America); some success when routing via NA VPN.
- Incognito does not consistently help. Example stores provided; videos/screenshots show checkout landing on “information” instead of “shipping” despite prefilled fields (attachments central to reproducing behavior).
Workarounds attempted
- Disable storefront password (widely restores checkout). Some used a “headless theme” + robots.txt.liquid to hide the shop subdomain; domain aliases may cause redirect loops.
Shopify response/status
- Support tickets opened (e.g., 33234945). One merchant reports Shopify applied a per-store temporary fix allowing password protection to be re-enabled.
- No confirmed global fix or timeline; behavior still reported by multiple merchants.
Current state
- Issue ongoing, appears Shopify-side and possibly geo-related. Recommended: contact Shopify support to escalate for a temporary fix; consider disabling password protection as a stopgap.
