# Work with Shortcuts

The following are Apex classes for working with shortcuts.

## ShortcutDispatcher Class

Defines the dispatcher for the shortcut you are handling.

**Usage**

When a user interacts with your shortcut, your app receives an interaction payload. Your handler processes that payload and then sends a response. See [Handle Slack Actions](/docs/platform/salesforce-slack-sdk/guide/actions.md).

To respond to an interaction payload, always send an acknowledgement response, follow up with a modal to confirm any action that occurs next. See [Slack API: Responding to shortcuts](https://api.slack.com/interactivity/shortcuts/using#shortcut_response).

### ShortcutDispatcher Methods

`ShortcutDispatcher` has the following method.

#### invoke(parameters, context)

Invokes the action handler.

**Signature**

```java
public Slack.ActionHandler invoke(
  Slack.ShortcutParameters parameters,
  Slack.RequestContext context
);
```

**Parameters**

*parameters*

Type: [Slack.ShortcutParameters](/docs/platform/salesforce-slack-sdk/guide/apex_ref_shortcut.md)

The action parameters for the shortcut handler. The format is a `Map<String, Object>`.

*context*

Type: [Slack.RequestContext](/docs/platform/salesforce-slack-sdk/guide/apex_ref_requestcontext.md)

Describes the context in which a Slack action is invoked.

**Return Value**

Type: [Slack.ActionHandler](/docs/platform/salesforce-slack-sdk/guide/apex_ref_dispatchers.md)

**Usage**

To access the Slack context, use the `invoke()` method. This method is passed in by an instance of `RequestContext`. It exposes information about the source of the action in Slack, performs custom logic, and obtains the correct Slack client to respond to Slack based on the request.
Each action type receives different information in its `RequestContext`.
