Jak działa szablon automatyzacji Business WhatsApp AI RAG Chatbot w n8n

Przedstawiony szablon automatyzacji w n8n służy do stworzenia Business WhatsApp AI RAG (Retrieval-Augmented Generation) Chatbot. Poniżej znajdziesz szczegółowy opis działania oraz kroki konfiguracji.

Mechanizm działania

Webhook Setup: Proces rozpoczyna się od konfiguracji webhooków do weryfikacji i odpowiedzi. Webhook Verify odbiera żądania GET i wysyła kod weryfikacyjny, natomiast Respond webhook obsługuje przychodzące żądania POST od Meta dotyczące wiadomości WhatsApp.

Message Handling: Po odebraniu wiadomości, workflow sprawdza, czy przychodzący JSON zawiera wiadomość użytkownika. Jeśli tak, wiadomość jest przetwarzana dalej; w przeciwnym razie wysyłana jest ogólna odpowiedź.

AI Agent Interaction: Wiadomość użytkownika jest przekazywana do węzła AI Agent, który wykorzystuje agenta konwersacyjnego z predefiniowanym komunikatem systemowym dostosowanym do sklepu elektronicznego. Dzięki temu AI zapewnia dokładne i profesjonalne odpowiedzi oparte na bazie wiedzy.

Knowledge Base Utilization: AI Agent korzysta z bazy wiedzy przechowywanej w Qdrant, bazie danych wektorowych. Dokumenty z Google Drive są pobierane, wektoryzowane przy użyciu osadzeń OpenAI i przechowywane w Qdrant do wykorzystania podczas konwersacji.

Response Generation: AI Agent generuje odpowiedź przy użyciu modelu chat OpenAI (gpt-4o-mini) i wysyła ją z powrotem do użytkownika przez WhatsApp.

Kroki konfiguracji

  • Create Qdrant Collection:
    • Zaktualizuj zmienne QDRANTURL i COLLECTION w workflow.
    • Użyj węzła Create collection HTTP request, aby zainicjować kolekcję w Qdrant.
  • Vectorize Documents:
    • Skonfiguruj węzły Get folder i Download Files, aby pobrać dokumenty z określonego folderu Google Drive.
    • Użyj węzła Embeddings OpenAI, aby wygenerować osadzenia dla pobranych plików.
    • Przechowuj zwektoryzowane dokumenty w Qdrant przy użyciu węzła Qdrant Vector Store.
  • Configure Webhooks:
    • Upewnij się, że oba webhooki Verify i Respond mają ten sam URL.
    • Ustaw webhook Verify na metodę HTTP GET, a Respond na POST.
  • Set Up AI Agent:
    • Zdefiniuj prompt systemowy dla AI Agent, określając wytyczne dotyczące informacji o produktach, wsparcia technicznego, obsługi klienta i korzystania z bazy wiedzy.
    • Połącz AI Agent z modelem chat OpenAI i skonfiguruj ewentualne dodatkowe narzędzia.
  • Test Workflow:
    • Ręcznie wyzwól workflow przy użyciu węzła When clicking ‘Test workflow’, aby upewnić się, że wszystkie komponenty działają poprawnie.
    • Monitoruj przepływ danych przez węzły i sprawdź, czy odpowiedzi są generowane i wysyłane poprawnie.

Przykłady zastosowań

Ten szablon automatyzacji może być wykorzystany w różnych scenariuszach biznesowych, szczególnie w obszarze obsługi klienta i sprzedaży. Oto kilka potencjalnych zastosowań:

  • Automatyczna obsługa zapytań klientów dotyczących produktów w sklepie internetowym.
