strRequest = “UN~demo123|PSWD~demo123|TERMS~Y|METHOD~ProcessTranx|”

Example of Parsing a Refund Response
‘declare tools to loop through the response and store the current name / value pair
Dim arrResponse() as String
Dim arrPair() as String
Dim Counter as Integer
‘declare the tools to store the values of the appropriate responses
Dim strError As String
Dim strResponseMessage As String
Dim strTransactionID As String
‘check to make sure the response was not empty/invalid
if strResponse <> “” and inStr(strResponse,”|”) > 0 and inStr(strResponse,”~”) > 0 then
arrResponse = split(strResponse, “|”) ‘split the response into an array of name/value pairs
for Counter = 0 to uBound(arrResponse)-1
arrPair = split(arrResponse(Counter), “~”)
If UCase(arrPair(0)) = "ERROR" Then
StrError = strError & arrPair(1)
ElseIf UCase(arrPair(0)) = "RESPONSE" Then
strResponseMessage = arrPair(1)
ElseIf UCase(arrPair(0)) = "TRANSACTIONID" Then
strTransactionID = arrPair(1)
End If
next
Else
StrError = StrError & “The response from the PayTrace API was invalid."
End if
If StrError <> “” then
MsgBox “Transaction was not successful per the following error: ” & StrError
Else
MsgBox “Transaction was successful: ” & strResponseMessage
