This n8n workflow automates responses across WhatsApp, Instagram, and Facebook Messenger by integrating Meta’s APIs with an AI-powered virtual assistant. When a message is received via WhatsApp trigger or webhooks from Instagram or Facebook, the workflow processes and categorizes the message based on the platform. It then leverages a language model (Ollama) to generate a context-aware, friendly response. The reply is sent back to the user via the corresponding messaging platform. This setup is ideal for businesses seeking to offer instant, personalized support and engagement across multiple social channels, streamlining customer interactions and maintaining a consistent brand voice.
