Can one (URL) web service has multiple service interfaces

Hi,

My scenario will be webservice to proxy.

when ever third party triggers single URL then whatever services interfaces defined in ESR should be called. In ID I do have only one sender agreement but it has three service interfaces when I generate a WSDL or URL , is that capture all service interfaces in URL. third party consumes webservice with URL . are they able to trigger based on service interface to send data.

Thanks

Praveen
