ValidateCreditCard

The ValidateCreditCard function is used to Validate a CreditCard Number by using an algorithm that not only runs a Modulus Check on the card number but also returns the card type by checking the number against a list of valid Bank Identification Numbers (BINs). A formal description of the function can be found in the 'Service Description' section of

http://ws.esortcode.com/bankdetails.asmx

or for a sample SOAP request and response

http://ws.esortcode.com/bankdetails.asmx?op=ValidateCreditCard

The ValidateAccount method takes 5 parameters

Parameter	Parameter Description
sCreditCardNumber	The Credit Card Number
sUserName	The unique Account Name given to you when you register
sGUID	The Globally Unique Identifier(GUID) assigned to you when you register
sIPAddress	IP Address. (Leave this blank)

and can be invoked as follows replacing the 'string' values where appropriate:

Response = http://ws.esortcode.com/bankdetails.asmx/ValidateCreditCard?sCreditCardNumber=string&sCardType=string&sUserName=string&sGUID=string&sIPAddress=string

A typical Valid response will look something like this:

<?xml version="1.0" encoding="utf-8" ?> -     <Validation xmlns:xsd="http://www.w3.org/2001/XMLSchema"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://ws.esortcode.com">           <ValidationMessage>VALID</ValidationMessage>           <IsError>false</IsError>           <ErrorMessage />       </Validation>

The response returns 4 fields and will have one of the following formats:
 

ValidationMessage	CardType	IsError	ErrorMessage
VALID	Card Type	false	blank
INVALID : "Invalid Reason here"	blank	false	blank
blank	blank	true	ERROR : "Error Message here"
