Hey everyone,

about 50% of my abandoned carts on my store have the following error message from PayPal:

PaymentAction of Authorization is not allowed with Unilateral and Non-Credentialed authentication.

does anyone know what is causing this message to appear? It’s costing me a fortune in lost sales.

Thanks

Hey @StrikingViper69 ,

Thanks for reaching out!

The error message you’re encountering typically arises when there’s an issue with the PayPal account setup.

  • Unilateral Payments: This error often occurs when a payment is attempted to be sent to an email address that is not confirmed or not associated with a PayPal account.

Previously, I have seen merchants figure out that the cause of this error was that the email address on their Paypal business account was not verified. PayPal technical support should be able to help out. Once the email address is verified, everything should start working as normal!

Thanks Moira,

I think my email address is verified, I’ve been using it for years.

I’m in contact with PayPals technical support and hopefully going to get a solution from them,

Don’t hesitate to reach back out if you require any further assistance as you continue to work on your store.

All the best,

hi, did you manage to solve this issue? I am getting the same error in my store..thanks!

I disconnected PayPal, then set it up again, that seemed to work and I’m no longer getting the error.

I’m guessing either PayPal or Shopify updated something and it partially broke the existing integration.
