Integracja Voiceflow z n8n dla inteligentnych asystentów konwersacyjnych

Voiceflow to platforma no-code umożliwiająca projektowanie, prototypowanie i wdrażanie asystentów konwersacyjnych na różnych kanałach, takich jak czat, głos czy telefon. Dzięki zaawansowanej logice i zrozumieniu języka naturalnego, Voiceflow integruje się z API, webhookami oraz narzędziami takimi jak Twilio, co czyni go idealnym rozwiązaniem do budowy botów wsparcia klienta, asystentów głosowych czy inteligentnych chatbotów.

Opis automatyzacji

Ten workflow łączy n8n z Voiceflow, wykorzystując dodatkowo narzędzia takie jak Google Calendar, Qdrant (baza danych wektorowych), OpenAI oraz API śledzenia zamówień, aby stworzyć inteligentnego asystenta konwersacyjnego działającego na wielu kanałach.

Główne komponenty

Workflow opiera się na trzech głównych webhookach w n8n, z którymi komunikuje się Voiceflow:

  • n8n_order – odbiera zapytania dotyczące śledzenia zamówień, wysyła zapytanie do zewnętrznego API i zwraca status zamówienia.
  • n8n_appointment – przetwarza rezerwację wizyt, formatuje datę przy użyciu OpenAI i tworzy wydarzenie w Google Calendar.
  • n8n_rag – odpowiada na ogólne pytania dotyczące produktów/usług, wykorzystując system RAG (Retrieval-Augmented Generation) zintegrowany z Google Drive, Qdrant i OpenAI.

Jak to działa

Workflow rozpoczyna się od wyzwalacza w postaci trzech webhooków, które odbierają dane z Voiceflow. Każdy webhook kieruje żądanie do odpowiedniej funkcji:

  • Śledzenie zamówień – pobiera status zamówienia z zewnętrznego API.
  • Rezerwacja wizyt – parsuje datę za pomocą OpenAI, tworzy wydarzenie w Google Calendar i wysyła potwierdzenie przez WhatsApp.
  • System RAG – przeszukuje bazę Qdrant (zasilaną dokumentami z Google Drive) i generuje odpowiedzi na pytania klientów przy użyciu GPT-4.

Przetwarzanie AI

  • Łańcuchy OpenAI – przekształcają daty w formacie naturalnym na format zrozumiały dla Google Calendar i generują odpowiedzi.
  • Pipeline RAG – przetwarza dokumenty (za pomocą OpenAI), przechowuje je w Qdrant i udostępnia odpowiedzi oparte na kontekście.
  • Integracja z Voiceflow – przekazuje odpowiedzi z powrotem do Voiceflow, aby dostarczyć je na wybrany kanał (czat, głos lub telefon).

Wymagane konfiguracje

  • API – wymagane są klucze dostępu do Google Calendar, Google Drive, Qdrant i OpenAI.
  • Konfiguracja Qdrant – należy utworzyć kolekcję i zasilić ją danymi z Google Drive przy użyciu embeddings OpenAI.
  • Webhooki Voiceflow – należy połączyć bloki "Capture" w Voiceflow z odpowiednimi webhookami w n8n.
  • Google Calendar – wymaga autoryzacji i ustawienia szablonów wydarzeń.

Przykłady zastosowań

Ta automatyzacja może być wykorzystana w wielu scenariuszach biznesowych, takich jak:

  • Automatyczne śledzenie statusu zamówień dla klientów e-commerce.
  • Rezerwacja wizyt u lekarza lub w salonach usługowych z potwierdzeniem przez WhatsApp.
  • Wsparcie techniczne dla produktów, z automatycznym wyszukiwaniem rozwiązań w bazie wiedzy.
  • Asystent głosowy w call center, integrujący się z Twilio do obsługi połączeń telefonicznych.
  • Automatyzacja odpowiedzi na FAQ w sklepach internetowych.
  • Wirtualny asystent w bankowości, pomagający w sprawdzaniu salda lub historii transakcji.
  • System rekomendacji produktów oparty na zapytaniach klientów.

Dodatkowe możliwości

  • Integracja z Twilio, aby przekształcić asystenta w Phone Agent.
  • Dostosowanie promptów OpenAI dla lepszej precyzji i tonu odpowiedzi.
