# callApex()

Makes an Apex call.

## Sample

Used within a JavaScript app uploaded as a static resource and referenced by `lightning:container`, this example calls the Apex method `getAccount`.

```javascript
  callApex() {
    LCC.callApex(
        "lcc1.ApexController.getAccount",
        this.state.name,
        this.handleAccountQueryResponse,
        { escape: true }
    );
}
```

When the Apex method you are calling doesn't require any parameters, pass an empty array.

```nolang
callApex() {
    LCC.callApex(
        "lcc1.ApexController.getAccountWithNoParams",
        [], // Empty array for no parameters
        this.handleAccountQueryResponse,
        { escape: true }
    );
}
```
