# Creating a Canvas App Event

The following code example shows how to call the `publish` method to create a canvas app event. If you’re using a namespace, the event name must be prefaced by the namespace. For example, `namespace.eventName`.

```java
Sfdc.canvas(function() {
    sr = JSON.parse('<%=signedRequestJson%>');
    Sfdc.canvas.client.publish(sr.client,
        {name : "mynamespace.statusChanged", payload : {status : 'Completed'}});
});
```
