How it works / What it does

This workflow creates an intelligent WhatsApp cooking assistant that transforms simple ingredient lists into personalized recipe suggestions. The system:

  1. Receives WhatsApp messages through webhook triggers
  2. Analyzes user input using Google Gemini AI to extract ingredients, dietary needs, and preferences
  3. Maps user requests to FatSecret API parameters automatically
  4. Searches recipe database based on extracted criteria (ingredients, calories, time, cuisine, etc.)
  5. Processes API results to format recipe suggestions with images and nutritional info
  6. Maintains conversation context using memory buffer for better user experience
  7. Sends formatted responses back to users via WhatsApp

Key Innovation: AI-Powered Parameter Extraction - Unlike traditional recipe apps that require users to fill out forms or select from predefined options, this system understands natural language requests and automatically maps them to the appropriate API parameters, making recipe discovery as simple as texting a friend.
