Have a look at the webservicequery and a!wsConfig used here: forum.appian.com/.../SAIL_Recipes.html

It seems to me that, if you have no actual input defined to the webservice, you need to define the input as something like:

{
          helloNameRequest: {}
}

...and, if you have an input (eg an id), it would be something like:

{
          helloNameRequest: {
                    id: ri!someId
          }
}

Thanks Philb. It works fine

No problem :)
