Consume an external web service (exchange rates) in AX 2009

Hi,

During my career I have never had the opportunity to write X++ code that consumes an external web services...

I am trying to get exchange rates from the Swedish Riksbank (the central bank of Sweden) through their web service API (https://swea.riksbank.se/sweaWS/docs/api/index.htm ).

I add a service reference in AX and enters the URL to the wsdl location (https://swea.riksbank.se/sweaWS/wsdl/sweaWS.wsdl ). Then I create a class with a method which looks something like this:

public static server Exchrate getRate()
{
    netCurrencyService.SweaWebServicePortTypeClient soapClient;
    ExchRate conversionrate;
    str rates[2];

    ;

    try
    {
        new InteropPermission(InteropKind::ClrInterop).assert();

        soapClient = new netCurrencyService.SweaWebServicePortTypeClient();

        rates[1] = "SEKUSDPMI";
        rates[2] = "SEKGBPPMI";


        conversionrate = soapClient.getLatestInterestAndExchangeRates("en", rates);
        CodeAccessPermission::revertAssert();

        return conversionrate;

    }
    catch(Exception::CLRError)
    {
        throw error(AifUtil::getClrErrorMessage());
    }

}

My problem is that the code does not compile. The call "soapClient.getLatestInterestAndExchangeRates("en", rates)" indicates that argument 2 ("rates") is incorrect. If I enter a string instead the compiler says that the class  netCurrencyService.SweaWebServicePortTypeClient doesn't include this function ("getLatestInterestAndExchangeRates"?).

Any suggestions?
