Jak działa ten szablon automatyzacji

Ten szablon n8n tworzy prostego bota WhatsApp działającego jako Agent Sprzedaży. Agent korzysta z bazy danych produktów w formie vector store, aby lepiej odpowiadać na pytania użytkowników.

Szablon składa się z dwóch głównych części:

  • Tworzenie vector store z katalogiem produktów
  • Budowa chatbotu AI na WhatsApp

Proces działania:

  1. Brochura produktowa jest importowana przez węzeł HTTP request, a jej zawartość tekstowa jest wyodrębniana
  2. Zawartość tekstowa jest przesyłana do vector store w pamięci, aby zbudować bazę wiedzy dla chatbotu
  3. Trigger WhatsApp przechwytuje wiadomości od klientów, filtrując wiadomości nietekstowe
  4. Wiadomość klienta jest wysyłana do Agenta AI, który przeszukuje katalog produktów korzystając z narzędzia vector store
  5. Odpowiedź Agenta jest wysyłana z powrotem do użytkownika przez węzeł WhatsApp

Instrukcja użycia

Aby skorzystać z tego szablonu:

  1. Skonfiguruj swoje konto WhatsApp Business i wprowadź dane uwierzytelniające
  2. Wypełnij vector store, klikając przycisk "Test Workflow"
  3. Aktywuj workflow, aby włączyć chatbot WhatsApp
  4. Wyślij wiadomość na wybrany numer WhatsApp, a otrzymasz odpowiedź od Agenta Sprzedaży AI
  5. Dostosuj źródło danych i zachowanie zgodnie z potrzebami

Wymagania

  • Konto WhatsApp Business
  • OpenAI do obsługi modelu językowego (LLM)

Dostosowywanie workflow

Możesz rozbudować ten szablon poprzez:

  • Zastąpienie vector store rozwiązaniem Qdrant dla trwałości danych i zastosowań produkcyjnych
  • Obsługę różnych typów wiadomości WhatsApp dla bogatszego doświadczenia klientów

Przykłady zastosowań

Ten szablon automatyzacji może być wykorzystany w różnych scenariuszach biznesowych:

  • Automatyczna obsługa zapytań o produkty w sklepie internetowym
  • Natychmiastowe udzielanie odpowiedzi na pytania dotyczące specyfikacji produktów
  • Prowadzenie klientów przez proces zakupowy w WhatsApp
  • Zbieranie informacji o preferencjach klientów na podstawie ich pytań
  • Automatyczne sugerowanie powiązanych produktów w oparciu o zapytania
  • Obsługa często zadawanych pytań (FAQ) bez udziału człowieka
  • Wstępna kwalifikacja leadów sprzedażowych przed przekazaniem do działu sprzedaży
