[TUTORIAL] Auto-Posting Threads to XenForo 2.x via REST API & n8n

You do not need to buy expensive XenForo auto-poster add-ons. XenForo 2.x has a built-in REST API that allows you to automatically create threads, post replies, and manage users using free workflow tools like n8n or Make.com.

---

Step 1: Enabling the XenForo API

1. Go to your XenForo Admin Control Panel.
2. Navigate to Setup > API keys.
3. Create a new Super User API key. Check the scopes for node:read and thread:write.
4. Copy the generated API Key. Keep it secret.

Step 2: The HTTP Request in n8n
In your n8n workflow, add an "HTTP Request" node. Configure it to send a POST request to your forum to create a new thread.

// n8n HTTP Request Configuration
{
  "Method": "POST",
  "URL": "https://yourforum.com/api/threads/",
  "Authentication": "Header Auth",
  "Headers": {
    "XF-Api-Key": "YOUR_API_KEY",
    "Content-Type": "application/x-www-form-urlencoded"
  },
  "Body": {
    "node_id": 12, // The ID of the category you want to post in
    "title": "Automated Daily Crypto Update",
    "message": "Here is the parsed data for today..."
  }
}

Pro Tip: You can connect an RSS Feed node before this HTTP Request node to automatically pull news from other sites and publish them instantly to your XenForo nodes.
