Why is the PayPal express setup failing in my Shopify store due to email mismatch?

Shopify Discussion

Topic summary

PayPal Express Checkout failing due to an email mismatch after a Shopify store ownership transfer. Shopify auto-creates a PayPal Express connection using the email present when the store is opened; this appears to remain bound to the developer’s email even after ownership changes.

Recent outcome: A PayPal order failed because the PayPal-linked email doesn’t match the developer’s email. The Shopify admin shows the client’s owner email as linked, but transactions still seem tied to the original email in the backend.

Actions tried: Deactivated and reactivated PayPal Express twice; issue persists. Shopify Support advised adding the developer’s email to the client’s PayPal account and verifying it.

Concerns: Sharing access to the client’s financial account is considered insecure and inappropriate by the developer.

Suggestions from the community:

  • Fully deactivate/remove the existing PayPal Express link and set up a fresh connection using the client’s email.
  • Consider alternative payment gateways.
  • Re-engage Shopify Support to resolve without granting developer financial access.

Status: Unresolved; key question is how to rebind PayPal Express to the client’s email securely without exposing or using the developer’s email.

Hi @joanlaura ,
This is Theodore from PageFly - Shopify Page Builder App.

Sharing your client’s financial information is a serious security risk and should never be done. There are alternative solutions to address the PayPal Express issue:

Deactivate the existing account and set up a new one using the client’s email.
Explore alternative payment gateways that don’t require linking their personal PayPal account.
Contact Shopify Support for assistance in resolving the issue while maintaining financial security.

Best regards,
