Send messages

Messages are the building blocks of apps and bots. Start from “Hello, world,” or connect a service you already use.

Give users a shortcut

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.

Latest from the changelog

Jan 25, 2021

Your app can now count its workflow steps with the help of four new events: workflow_published, workflow_unpublished, workflow_deleted, and workflow_step_deleted. Use these events to stay informed on workflows—from unpublished to published and back again—that make use of steps powered by your app.

Jan 10, 2021

Socket Mode supplies your app with events and interactive feature payloads over a dynamic WebSocket URL. Read more on the new way to skip static, public HTTP endpoints—now supported by all SDKs.
