You can use the URL query string format to include parameters in the message body of an Oracle ATG Web Commerce platform REST Web Services request.

Include the parameters in standard URL query string format as shown in the example below. Include each parameter in a separate name and value pair. Use the name of the parameter as the name for the pair. For positional parameters that do not have names, use the arg1, arg2, arg3 convention as the names for the pairs. See Positional Parameters.

arg1=MyUsername&arg2=MyPassword&atg-rest-user-input=MyMessageId

URL encode any special URL characters in the parameter values. Make sure that you specify Content-Type: application/x-www-form-urlencoded in the HTTP message. See Setting the Content-Type Value.
