# Slack

Slack is a team communication and collaboration tool. This API allows you to interact with Slack in two ways: as a bot for automated tasks and workflows, or as a user to perform actions on behalf of a real Slack user. Whether you're building chatbots, automating workflows, or integrating Slack with other tools, this API provides the flexibility to suit your needs.

- Category: Communication
- Connection: Sign in. Sign in with your Slack account. No API key to copy.
