Is there a way to pass an optional parameter to a webservice, instead of having to overload the method?

If the webservice user is accessing the webservice directly, I want to do ActionA, if the user is accessing the webservice through my web interface, I want to do ActionA + ActionB.

    no, you can’t really have optional params for a service.

    Even if an input parameter for a Web
    service method is optional, you must
    still include it and set the parameter
    value to null

    Supplying Web Service Method Arguments

    So, its optional to a degree, that you dont have to supply a value, but you’re still going to have to write null instead. Overloading is the ‘normal’ way to do this.
