First understand what is WSDL according to standard definition

WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint.

So basically WSDL is metadata of your service which provide the description about any service. For running any service there is need of three basic component

1. Address(url)
2. Binding(protocol)
3. Service (Which service is running on that address.)

The cumulative is known as endpoints.

Since Restful service only use http(s) protocol to run service so there is not much information is needed for restful services only address of restful service is enough.Hence there is not need of metadata and WSDL document in Restful service. But for other kind of service (like SOAP based) built on WCF framework WSDL document is necessary to expose there information to client so that client can utilize that WSDL document to customize itself according to service.
