Generates SEO blog posts, ad copy, email sequences, and social captions using Claude AI.

Setup

  1. Add your ANTHROPIC_API_KEY in the Set Config node
  2. Configure Serper API key for SEO data (optional)
  3. Set your WordPress, Mailchimp, Airtable credentials
  4. POST to the webhook URL

Webhook Payload

{
  "topic": "Best AI Tools 2025",
  "contentType": "blog_post",
  "keyword": "ai tools for marketing",
  "tone": "professional",
  "audience": "SMB marketers",
  "wordCount": 1500,
  "brand": "YourBrand",
  "clientEmail": "[email protected]"
}

Content Types

  • blog_post
  • ad_copy
  • email_sequence
  • social_captions

Flow

The simplified flow (9 active nodes):

Receive Brief → Set Config → Fetch SERP Data → Build Claude Prompt
→ Call Claude AI → Parse Claude Response → Save to Google Sheets
                                         → Send Delivery Email
                                         → Send Response

After importing, replace these 5 values in the Set Config node:

Field Replace with
YOUR_ANTHROPIC_API_KEY Your Anthropic key
YOUR_SERPER_API_KEY Your Serper.dev key (free tier works)
YOUR_SENDGRID_API_KEY Your SendGrid key
YOUR_GOOGLE_SHEET_ID Your Sheet ID from the URL
YOUR_GSHEETS_CREDENTIAL_ID Set up Google Sheets OAuth in n8n credentials

The workflow handles all 4 content types (blog_post, ad_copy, email_sequence, social_captions) through a single Claude call with type-specific prompts — no branching needed.
