n8n WhatsApp to Social Media Content Generation with GPT-4 & Approval Workflow
This n8n workflow automates the process of generating social media content from WhatsApp messages using GPT-4, incorporating an approval step before publishing to various platforms. It allows for efficient content creation and ensures human oversight.
What it does
This workflow streamlines your content creation by:
- Receiving WhatsApp Messages: It expects to be triggered by an external system (e.g., a WhatsApp webhook) sending message content to an HTTP Request node.
- Generating Social Media Content with AI: It uses an AI Agent powered by an OpenAI Chat Model (GPT-4) and a SerpAPI (Google Search) tool to understand the WhatsApp message and generate suitable social media posts. A Structured Output Parser extracts the generated content in a defined format.
- Human-in-the-Loop Approval: It sends the generated content to a specified email address (via Gmail) for review and approval.
- Conditional Publishing: Based on the approval decision, it proceeds to publish the content.
- Publishing to Social Media: If approved, it publishes the generated content to Facebook, X (formerly Twitter), and LinkedIn.
- Handling Rejection: If the content is rejected, it does not publish to social media.
- Aggregating Results: It combines the outcomes of the publishing steps (or lack thereof) for a complete workflow record.
Prerequisites/Requirements
To use this workflow, you will need:
- n8n Instance: A running n8n instance.
- WhatsApp Integration: An external service or webhook configured to send WhatsApp messages to the n8n HTTP Request node.
- OpenAI API Key: For the OpenAI Chat Model (GPT-4).
- SerpAPI Key: For the SerpAPI (Google Search) tool.
- Gmail Account: Configured as a credential in n8n for sending approval emails.
- Facebook Graph API Credentials: For publishing to Facebook.
- X (formerly Twitter) API Credentials: For publishing to X.
- LinkedIn API Credentials: For publishing to LinkedIn.
Setup/Usage
- Import the Workflow: Import the provided JSON into your n8n instance.
- Configure Credentials:
- Set up your OpenAI credentials for the "OpenAI Chat Model" node.
- Set up your SerpAPI credentials for the "SerpAPI (Google Search)" node.
- Set up your Gmail credentials for the "Gmail" node.
- Set up your Facebook Graph API credentials for the "Facebook Graph API" node.
- Set up your X (formerly Twitter) credentials for the "X" node.
- Set up your LinkedIn credentials for the "LinkedIn" node.
- Configure the HTTP Request Trigger:
- The "HTTP Request" node acts as the entry point. Configure your external WhatsApp integration to send message data to this node's webhook URL.
- The expected input should contain the WhatsApp message text that the AI will use for content generation.
- Customize AI Agent (Optional):
- Review the "AI Agent" node to understand how it's configured to generate social media content. You might want to adjust the prompt or tools based on your specific content needs.
- The "Structured Output Parser" node expects a specific JSON format from the AI. Ensure your AI output matches this or adjust the parser accordingly.
- Configure Approval Email:
- In the "Gmail" node, specify the recipient email address(es) for the approval requests.
- Customize the email subject and body as needed to clearly present the generated content for approval.
- Activate the Workflow: Once all credentials and configurations are set, activate the workflow.
Now, when a WhatsApp message is received by the HTTP Request node, the workflow will automatically generate social media content, send it for approval, and publish it to your chosen platforms upon approval.

By Daniel NkenchoSynchronizing WooCommerce inventory and creating products with Google Gemini AI and BrowserAct
Synchronize WooCommerce Inventory & Create Products with Gemini AI & BrowserAct This sophisticated n8n template automates WooCommerce inventory management by scraping supplier data, updating existing products, and intelligently creating new ones with AI-formatted descriptions. This workflow is essential for e-commerce operators, dropshippers, and inventory managers who need to ensure their product pricing and stock levels are synchronized with multiple third-party suppliers, minimizing overselling and maximizing profit. --- Self-Hosted Only This Workflow uses a community contribution and is designed and tested for self-hosted n8n instances only. --- How it works The workflow is typically run by a Schedule Trigger (though a Manual Trigger is also shown) to check stock automatically. It reads a list of suppliers and their inventory page URLs from a central Google Sheet. The workflow loops through each supplier: A BrowserAct node scrapes the current stock and price data from the supplier's inventory page. A Code node parses this bulk data into individual product items. It then loops through each individual product found. The workflow checks WooCommerce to see if the product already exists based on its name. If the product exists: It proceeds to update the existing product's price and stock quantity. If the product DOES NOT exist: An If node checks if the missing product's category matches a predefined type (optional filtering). If it passes the filter, a second BrowserAct workflow scrapes detailed product attributes from a dedicated product page (e.g., DigiKey). An AI Agent (Gemini) transforms these attributes into a specific, styled HTML table for the product description. Finally, the product is created in WooCommerce with all scraped details and the AI-generated description. Error Handling: Multiple Slack nodes are configured to alert your team immediately if any scraping task fails or if the product update/creation process encounters an issue. Note: This workflow does not support image uploads for new products. To enable this functionality, you must modify both the n8n and BrowserAct workflows. --- Requirements BrowserAct API account for web scraping BrowserAct n8n Community Node -> (n8n Nodes BrowserAct) BrowserAct templates named “WooCommerce Inventory & Stock Synchronization” and “WooCommerce Product Data Reconciliation” Google Sheets credentials for the supplier list WooCommerce credentials for product management Google Gemini account for the AI Agent Slack credentials for error alerts --- Need Help?

By Madame AI Team | KaiAi website scraper & company intelligence
AI Website Scraper & Company Intelligence Description This workflow automates the process of transforming any website URL into a structured, intelligent company profile. It's triggered by a form, allowing a user to submit a website and choose between a "basic" or "deep" scrape. The workflow extracts key information (mission, services, contacts, SEO keywords), stores it in a structured Supabase database, and archives a full JSON backup to Google Drive. It also features a secondary AI agent that automatically finds and saves competitors for each company, building a rich, interconnected database of company intelligence. --- Quick Implementation Steps Import the Workflow: Import the provided JSON file into your n8n instance. Install Custom Community Node: You must install the community node from: https://www.npmjs.com/package/n8n-nodes-crawl-and-scrape FIRECRAWL N8N Documentation https://docs.firecrawl.dev/developer-guides/workflow-automation/n8n Install Additional Nodes: n8n-nodes-crawl-and-scrape and n8n-nodes-mcp fire crawl mcp . Set up Credentials: Create credentials in n8n for FIRE CRAWL API,Supabase, Mistral AI, and Google Drive. Configure API Key (CRITICAL): Open the Web Search tool node. Go to Parameters → Headers and replace the hardcoded Tavily AI API key with your own. Configure Supabase Nodes: Assign your Supabase credential to all Supabase nodes. Ensure table names (e.g., companies, competitors) match your schema. Configure Google Drive Nodes: Assign your Google Drive credential to the Google Drive2 and save to Google Drive1 nodes. Select the correct Folder ID. Activate Workflow: Turn on the workflow and open the Webhook URL in the “On form submission” node to access the form. --- What It Does Form Trigger Captures user input: “Website URL” and “Scraping Type” (basic or deep). Scraping Router A Switch node routes the flow: Deep Scraping → AI-based MCP Firecrawler agent. Basic Scraping → Crawlee node. Deep Scraping (Firecrawl AI Agent) Uses Firecrawl and Tavily Web Search. Extracts a detailed JSON profile: mission, services, contacts, SEO keywords, etc. Basic Scraping (Crawlee) Uses Crawl and Scrape node to collect raw text. A Mistral-based AI extractor structures the data into JSON. Data Storage Stores structured data in Supabase tables (companies, company_basicprofiles). Archives a full JSON backup to Google Drive. Automated Competitor Analysis Runs after a deep scrape. Uses Tavily web search to find competitors (e.g., from Crunchbase). Saves competitor data to Supabase, linked by company_id. --- Who's It For Sales & Marketing Teams: Enrich leads with deep company info. Market Researchers: Build structured, searchable company databases. B2B Data Providers: Automate company intelligence collection. Developers: Use as a base for RAG or enrichment pipelines. --- Requirements n8n instance (self-hosted or cloud) Supabase Account: With tables like companies, competitors, social_links, etc. Mistral AI API Key Google Drive Credentials Tavily AI API Key (Optional) Custom Nodes: n8n-nodes-crawl-and-scrape --- How It Works Flow Summary Form Trigger: Captures “Website URL” and “Scraping Type”. Switch Node: deep → MCP Firecrawler (AI Agent). basic → Crawl and Scrape node. Scraping & Extraction: Deep path: Firecrawler → JSON structure. Basic path: Crawlee → Mistral extractor → JSON. Storage: Save JSON to Supabase. Archive in Google Drive. Competitor Analysis (Deep Only): Finds competitors via Tavily. Saves to Supabase competitors table. End: Finishes with a No Operation node. --- How To Set Up Import workflow JSON. Install community nodes (especially n8n-nodes-crawl-and-scrape from npm). Configure credentials (Supabase, Mistral AI, Google Drive). Add your Tavily API key. Connect Supabase and Drive nodes properly. Fix disconnected “basic” path if needed. Activate workflow. Test via the webhook form URL. --- How To Customize Change LLMs: Swap Mistral for OpenAI or Claude. Edit Scraper Prompts: Modify system prompts in AI agent nodes. Change Extraction Schema: Update JSON Schema in extractor nodes. Fix Relational Tables: Add Items node before Supabase inserts for arrays (social links, keywords). Enhance Automation: Add email/slack notifications, or replace form trigger with a Google Sheets trigger. --- Add-ons Automated Trigger: Run on new sheet rows. Notifications: Email or Slack alerts after completion. RAG Integration: Use the Supabase database as a chatbot knowledge source. --- Use Case Examples Sales Lead Enrichment: Instantly get company + competitor data from a URL. Market Research: Collect and compare companies in a niche. B2B Database Creation: Build a proprietary company dataset. --- WORKFLOW IMAGE --- Troubleshooting Guide | Issue | Possible Cause | Solution | |-------|----------------|-----------| | Form Trigger 404 | Workflow not active | Activate the workflow | | Web Search Tool fails | Missing Tavily API key | Replace the placeholder key | | FIRECRAWLER / find competitor fails | Missing MCP node | Install n8n-nodes-mcp | | Basic scrape does nothing | Switch node path disconnected | Reconnect “basic” output | | Supabase node error | Wrong table/column names | Match schema exactly | --- Need Help or More Workflows?
