# Custom Web Services

The table query's `wire.data.select` will work with custom web services.  However, an alternative syntax can also be used for creating calls to custom web services using the `wire.data.call` method and it's associated `param` method for any parameters that the web service method may require.

```javascript
const query = wire.data.call("Users")
    .param("userName", "apeters");
```

To add a custom object to a web service call that will be sent in body of the call, use the `body` method.

```javascript
const obj = {userName: "apeters"};
const query = wire.data.call("Users").body(obj);
```
