How do I add a REST query string without the 'name='

Hi,

I'm trying to build a REST query, but my issue is that the service I'm calling only requires a value following the '?' and I'm struggling on how to define this.  If I blank out the name in the settings, it still generates the '=', so my query string ends up as'?=value', which the service rejects.

So, how do I add a query without the 'name=' or '='.

Thanks
