Slack OAuth API

The Slack OAuth API implements the OAuth 2.0 flow that lets developers securely install Slack apps to workspaces and obtain access tokens with specific, granular scopes. An app redirects a user to Slack for consent; after approval, Slack returns an authorization code that the app exchanges for tokens (typically a bot token, and optionally a user token) to call the Web API within the granted permissions.
