# getCustomAction

Allows custom components to access a custom quick action and pass data or messages to it.

## Arguments

| Name       | Type   | Description                                           |

```

```javascript
actionApi.getCustomAction(args).then(function(customAction) {
  if (customAction) {
    customAction.subscribe(function(data) {
      // Handle quick action message
    });
    customAction.publish({
      message : "Hello Custom Action",
      Param1 : "This is a parameter"
    });
  }
}).catch(function(error) {
  // We can't find that custom action.
});
```
