Work with Slash Commands

The following are Apex classes for working with slash commands.

SlashCommandDispatcher Class

Defines the dispatcher for the slash command you are handling.

Usage

When a user interacts with your slash command, your app receives an interaction payload. Your handler processes that payload and then sends a response. See Handle Slack Actions.

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.

For example, you can post a message that contains a view when a user enters a slash command. See ChatPostMessageRequest
