Why can't I connect Pinterest to my Shopify account?

Topic summary

Users are experiencing a persistent connection loop when attempting to link Pinterest to their Shopify stores. The integration repeatedly returns to the “Connect to Pinterest” page without completing the authentication process.

Troubleshooting attempts that failed:

  • Switching browsers (Safari, Chrome, others)
  • Clearing browser cache and cookies
  • Using incognito/private browsing mode
  • Trying different devices and internet connections

Official support response:
Shopify support initially suggested browser-related fixes, then recommended contacting Pinterest’s app support team directly through their Shopify App Store listing.

Additional reported issues:

  • One user reported losing existing Pinterest and Google Analytics connections after clearing cache
  • Multiple users encounter grey screens showing “refused to connect” errors
  • Screenshots show connection failures at the authorization step

Potential solution identified:
A community member suggests the issue stems from geographic restrictions—users need a Pinterest ad account (distinct from a business account) which may not be available in all countries.

Current status:
The problem remains unresolved for most users as of 2025, with neither Shopify nor Pinterest support providing effective solutions. The geographic/ad account requirement theory is unconfirmed but represents the only actionable lead.

Just butting in here. I cleared my cache and now my store is no longer connected to Pinterest and Google Analytics. I can’t figure out what to do about it. My Pinterest business page now looks like it’s brand new, no pins, no photo, nothing. Analytics is not receiving data. Global site tag is installed. It was all working before I cleared my cache. Is there a simple explanation?
