Why did I get API error code 10426?

PayPal returned error code 10426 - Transaction refused because of an invalid argument. See additional error messages for details.

A transaction was refused because the ItemTotal amount is invalid.

Review the amount entered. PayPal payments can contain no more than two decimal places. You can try to resolve the error by number-formatting the amount in the coding language being used and limiting the decimal places to two or fewer digits

Note: See the Developer Portal for a complete list of NVP/SOAP API error codes.
