An argument port has a port name and an argument name. If an argument name contains a character that is not allowed in a port name, enter an argument name that differs from the port name. For example, you want to pass the argument "Cust-ID" to the web service, but the Data Integration Service does not allow the dash character (-) in port names. Enter "Cust-ID" as the argument name, but enter "CustID" as the port name.

The Data Integration Service appends the argument names and values for each argument port to the base URL as name=value pairs. You can configure multiple argument ports. The Data Integration Service separates multiple arguments in the request with an ampersand character (&).

For example:

If you define argument ports and URL ports in the transformation, the Data Integration Service appends the URL port values to the base URL, followed by the argument names and values.
