# Apex Reference for Slack

Use Apex classes in the `Slack` namespace to simplify your Slack app development.

The `Slack` namespace provides classes and methods for interacting with your Slack apps, such as creating handlers for Slack actions and events, and getting access to a Slack client.

Before you create a handler, you must configure the connection and view definition for your Slack App. When creating your handler, extend the dispatcher based on the type of operation you’re handling.

- Actions: `Slack.ActionDispatcher`
- Commands: `Slack.SlashCommandDispatcher`
- Events: `Slack.EventDispatcher`
- Shortcuts: `Slack.ShortcutDispatcher`

**tip:** To determine which classes and methods you need for your app, review the [permission scopes](https://developer.salesforce.com/docs/platform/salesforce-slack-sdk/build/scopes.md) your app requires to perform the tasks.

For more information, see [Handle Slack Actions](https://developer.salesforce.com/docs/platform/salesforce-slack-sdk/build/actions.md).

To make a call to Slack from an Apex trigger, use the [`@future` annotation](https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_annotation_future.htm), queuable apex, or another [asynchronous method](https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_async_overview.htm).
