Build Slack apps using Bolt framework with OAuth 2.0 authentication, Block Kit for interactive UI components, and event-driven workflows. Bolt handles request verification, token management, and API routing; Block Kit enables rich message layouts and interactive elements; OAuth secures user authorization across multiple workspaces.

Use Bolt's event and interactive component handlers with request verification to validate incoming payloads. Implement rate limiting, input validation, and proper error handling. Bolt abstracts the Events API and interactive request routing, reducing boilerplate while maintaining security and reliability at scale.

Block Kit is Slack's UI framework for building rich, interactive messages and modals. Combine Block Kit JSON definitions with Bolt handlers to respond to user interactions, trigger workflow steps, and update messages dynamically. Supports buttons, select menus, datepickers, and custom workflows.

Deploy using provided templates for local development, cloud platforms, and Slack App Marketplace. Multi-language support (JavaScript, Python, Java) enables flexible deployment. Templates include environment configuration, token management, and platform-specific guidance for seamless distribution.

Bolt includes OAuth 2.0 support through its built-in authorization middleware. Configure OAuth scopes, handle token refresh, and manage multi-workspace installations automatically. The @slack/oauth package provides additional flexibility for custom OAuth flows if needed.

Slack Web API enables direct calls to Slack methods (posting messages, managing users, accessing data). Events API delivers real-time notifications of workspace activity (messages, reactions, user actions). Together they provide comprehensive programmatic access to Slack's core functionality.
