Hi all!

I’m trying to use a web service of my payment provider by making SOAP  
calls to their server. I’m using the WSDL that is attached to this post  
(couldn’t add urls though [ruby-forum.com](http://ruby-forum.com))

For some reason I can’t seem to call the provided services. I always get  
the error “nil not allowed: currency” when trying to call a method that  
doesn’t even has currency (or Amount) as a parameter. Maybe I’m doing  
something very wrong here, but I can’t seem to figure out how to get  
this thing working.

The latest thing I came up with was:

```
    wsdl = SOAP::WSDLDriverFactory.new(WSDL)
    soap = @wsdl.create_rpc_driver
    soap.options["protocol.http.basic_auth"] << [WSDL, USER_ID,

```

PASSWORD]

```
    result = soap.cancel(:cancel => {
                                :modificationRequest => {
                                    :merchantAccount => 'myAccount',
                                    :originalReference =>

```

‘8343424242056’  
}  
})

Anyone got an idea?

Thanks!

Wouter

Ah, got it… After require ‘soap4r’ it works!
