Slack Bots API

Slack's bot APIs let you build apps that live in Slack and automate work by listening for events and taking actions in conversations. Using the Web API, your bot can post and schedule messages, reply in threads, manage channels, look up users, and access files or reactions; the Events API delivers message, reaction, and workflow events to your server so you can respond in real time. Bots can power slash commands, message shortcuts, and interactive UI elements (buttons, menus, modals built with Block Kit), and they can open modals or update messages dynamically. Installation and access are controlled via OAuth 2.0 scopes, with bot tokens used to authenticate API calls; you can receive events over HTTPS or via Socket Mode if you don't host a public endpoint. Together, these capabilities let you create assistants that answer questions, route approvals, connect external services, and streamline team processes directly inside Slack.
