## What it is
A Go client library covering most of the Slack Web API (api.slack.com) plus real-time messaging via WebSocket, Socket Mode, and the Events API. It provides a managed client for sending messages, querying users and groups, and handling Slack events in Go applications.

## Use cases
- send slack messages from a go application
- build a slack bot in golang
- fetch slack user and group info via api
- handle slack events with socket mode
- integrate slack notifications into a go service
- connect to slack rtm over websocket

## When to choose
- you are building a Go application or bot that talks to Slack
- you need broad coverage of Slack Web API endpoints plus real-time events
- you want a community-maintained, widely imported Slack SDK for Go

## When to avoid
- you need a stable v1 API - minor releases may include breaking changes
- your project is not in Go
- you only need simple incoming webhooks, where a plain HTTP call may suffice

## Facets
- artifact type: library
- maturity: active
- function: http-client, websocket, sdk
- domain: apis, developer-tools, messaging-platforms
- platform: go, cross-platform
