Help users discover what your app can do with Shortcuts.

Automate with workflows

Harness the power of apps, without the code.

Create simple interactions

Your app can respond to user activity, and buttons let users complete simple tasks (like requests and approvals).

Set up internal tools

Need a slash command or a bot just for your team? All our tools can be used for internal integrations.

Publish your app

Submit your app to the Slack App Directory, and reach millions of daily active Slack users.

New header blocks let you provide stronger delineation between groups of content in your app surfaces. Stay ahead of the game by learning how they work.

Previously, when a user mentioned an app that wasn't party to the conversation, the user could Invite the app to the conversation, Let Them Know, or Do Nothing. The Let Them Know button didn't work. We've fixed that mistake by removing the button, and updated our documentation on the app_mention event as well.
