Short Description: Deploy to environment
Usage Hint: [environment] [branch]

// Webhook Configuration
HTTP Method: POST
Path: slack-deploy
Response Mode: Last Node
Response Data: JSON

// Parse Slack Data
{
  "user_id": "{{$json.body.user_id}}",
  "user_name": "{{$json.body.user_name}}",
  "command": "{{$json.body.command}}",
  "text": "{{$json.body.text}}",  // Command parameters
  "channel_id": "{{$json.body.channel_id}}",
  "response_url": "{{$json.body.response_url}}"
}

// Must respond within 3 seconds!
HTTP Response Node {
  "response_type": "ephemeral",  // Only visible to user
  "text": "🚀 Deployment started...",
  "blocks": [{
    "type": "section",
    "text": {
      "type": "mrkdwn",
      "text": "*Deploying to {{environment}}*\nBranch: `{{branch}}`\nStatus: _In progress..._"
    }
  }]
}

Advanced Slash Commands met Parameters

// N8N Slash Command Parameter Parser

// Input: /task create "Bug fix" priority:high assignee:@john
const commandText = items[0].json.text;
const parts = commandText.match(/(?:[^\s"]+|"[^"]*")+/g);

const parsed = {
  action: parts[0],  // "create"
  title: parts[1].replace(/"/g, ''),  // "Bug fix"
  params: {}
};

// Parse key:value pairs
parts.slice(2).forEach(part => {
  if (part.includes(':')) {
    const [key, value] = part.split(':');
    parsed.params[key] = value;
  }
});

// Smart Command Router
switch(parsed.action) {
  case 'create':
    // Create task in Jira/Trello
    break;
  case 'deploy':
    // Trigger deployment pipeline
    break;
  case 'report':
    // Generate and send report
    break;
  default:
    // Show help message
}

return parsed;

Slack Bot Development: Intelligente Assistenten

  const userId = $json.event.user;
  const channelId = $json.event.channel;
  const message = $json.event.text.replace(/<@.*?>/, '').trim();
  
  // Extract thread context if exists
  const threadTs = $json.event.thread_ts || $json.event.ts;
  
  return {
    userId,
    channelId,
    message,
    threadTs,
    isThread: !!$json.event.thread_ts
  };
}

// 3. Conversation History (for context)

7. Employee Onboarding Workflow

Slack Trigger Node: Event-Driven Automation

De Slack Trigger node luistert naar events in real-time. Dit is krachtiger dan webhooks omdat het automatisch reconnect en geen URL configuratie vereist.

Event Types & Use Cases

Advanced Event Processing

// Multi-Event Handler with Context

// Slack Trigger: Any Event
const event = $json.event;
const eventType = event.type;

// Event Router
switch(eventType) {
  case 'message':
    // Check for mentions, keywords, sentiment
    if (event.text.includes('urgent')) {
      await handleUrgentMessage(event);
    }
    if (event.text.match(/@channel|@here/)) {
      await logImportantMessage(event);
    }
    break;
    
  case 'reaction_added':
    // Handle approval flows
    if (event.reaction === 'white_check_mark') {
      await processApproval(event.item);
    }
    break;
    
  case 'file_shared':
    // Process files based on type
    const file = await getFileInfo(event.file_id);
    if (file.mimetype.includes('spreadsheet')) {
      await processSpreadsheet(file);
    }
    break;
}

// Context Enrichment
async function enrichContext(event) {
  const user = await slack.users.info(event.user);
  const channel = await slack.conversations.info(event.channel);
  
  return {
    ...event,
    user_name: user.real_name,
    user_email: user.profile.email,
    channel_name: channel.name,
    is_private: channel.is_private
  };
}

Security & Best Practices

Slack automatisering vereist strenge security maatregelen. Hier zijn essentiële best practices voor production deployments.

Security Checklist

Slack Signature Verification

// Verify Slack Request Signature
const crypto = require('crypto');

function verifySlackSignature(request) {
  const signature = request.headers['x-slack-signature'];
  const timestamp = request.headers['x-slack-request-timestamp'];
  const body = request.rawBody;
  
  // Check timestamp to prevent replay attacks
  const time = Math.floor(Date.now() / 1000);
  if (Math.abs(time - timestamp) > 300) {
    throw new Error('Request timestamp too old');
  }
  
  // Create signature
  const sigBasestring = `v0:${timestamp}:${body}`;
  const mySignature = 'v0=' + crypto
    .createHmac('sha256', process.env.SLACK_SIGNING_SECRET)
    .update(sigBasestring, 'utf8')
    .digest('hex');
  
  // Compare signatures
  if (!crypto.timingSafeEqual(
    Buffer.from(mySignature, 'utf8'),
    Buffer.from(signature, 'utf8')
  )) {
    throw new Error('Invalid signature');
  }
  
  return true;
}
