Why did I get the error "Unable to process payment. Please contact the merchant as the shipping address provided by the merchant is invalid..."?

Your shopping cart or payment request includes the variable Address_Override=1. This tells PayPal not to allow buyers to edit their shipping address on the PayPal review page.

Remove the Address_Override variable from your API payment request.

Review HTML Variables for PayPal Payments Standard for additional information.
