Step-by-Step Build Guide
1
Set Up the Webhook Trigger
Add a Webhook trigger. Test it by sending a POST request with JSON body: {"topic": "N8N automation", "audience": "marketers", "tone": "professional"}. You can trigger this from Postman, a simple HTML form, or even a Slack slash command.
2
Add the Research OpenAI Node
OpenAI node. Model: gpt-4. System: "You are a research assistant. Be factual and concise." User: "List 7 key facts about: {{ $json.topic }}. Target audience: {{ $json.audience }}." Rename this node "Research" for clarity.
3
Add the Outline OpenAI Node
Another OpenAI node. System: "You are an SEO content strategist." User: "Create a structured blog post outline using these facts: {{ $('Research').item.json.message.content }}" Rename this node "Outline".
4
Write the Full Article
Third OpenAI node. System: "You are a professional content writer. Write in a {{ $('Webhook').item.json.tone }} tone." User: "Write an 800-word blog post for {{ $('Webhook').item.json.audience }} using this outline: {{ $('Outline').item.json.message.content }}"
5
Generate Social Media Copy
Fourth OpenAI node. System: "You write viral social media content." User: "From this blog post, create: 1) A LinkedIn post (150 words) 2) A Twitter/X thread (5 tweets). Article: {{ $('Write').item.json.message.content }}"
6
Save to Google Docs & Email
Google Docs node: Create a new document titled {{ $('Webhook').item.json.topic }} — {{ $now }}. Then Gmail node: send yourself the doc URL plus the social media copy. Activate the workflow, fire it, and watch content appear in minutes.
