PayPal Api on my site is not working properly. When a client fills out the credit card info and a Canadian postal code (instead of a US zip code) I get an error that the zip code is not correct, and the client can not make the payment.
Please, copy and paste the error code if any. Mostly the postal code is an optional on credit card processing of Paypal API. But, if it is required you should match the Paypal API script with your country code, so Paypal will automatically match it.
