**Problem:**

Here my problem is that I want to pass multiple parameter while calling a WCF rest service, but I am not able to pass multiple parameters to that WCF rest service. I want to pass userid and password and check for in it. If it is bob then allow to go ahead.

And when I am calling this url:

```
http://localhost:48401/ARService/Service.svc/rest/IsValidUser?userid=bob&password=bob

```

then I am getting this error on my web page:

> 
> Endpoint not found. Please see the service help page for constructing valid requests to the service.
> 
> 
> 

If somebody have idea how to call `IsValidUser` in my case with this function parameter. Please help me.
