+# Slack Integration
+
+## Overview
+
+OpenClaw's Slack integration supports both Socket Mode (default) and HTTP webhook modes for server deployments.
+
+## Setup Methods
+
+### Socket Mode (Default)
+
+- Requires App Token (`xapp-...`) and Bot Token (`xoxb-...`)
+- Minimal configuration involves enabling Socket Mode in Slack app settings and generating tokens
+- Supports optional User Token (`xoxp-...`) for read operations like history and reactions
+
+### HTTP Mode
+
+- Alternative for server deployments with HTTPS accessibility
+- Uses Events API, Interactivity, and Slash Commands via shared webhook URL
+- Requires Signing Secret and Bot Token configuration
+
+## Configuration Options
+
+The system allows per-channel customization including:
+
+- User allowlists and skill filtering
+- Custom system prompts per channel
+- Bot message handling preferences
+- Tool action gating (reactions, messages, pins, member info, emoji)
+
+## Threading Options
+
+Three reply modes control message threading behavior:
+
+- **off** (default): replies in main channel unless message is already threaded
+- **first**: initial reply threads, subsequent replies appear in main channel
+- **all**: all replies use threading
+
+Per-chat-type overrides enable different behaviors for direct messages, group chats, and channels.
+
+## Security Considerations
+
+Writes default to the bot token so state-changing actions stay scoped to the app's bot permissions. User token writes require explicit opt-in and should be carefully gated.
+
+Multi-bot environments need protective measures against reply loops.
+
+## DM Protection
+
+Pairing mode (default) requires unknown senders to exchange approval codes, with configurable allowlists for trusted users or open access alternatives.
