N8N Whatsapp AI Agent (met human in the loop)
Download de complete N8N workflow JSON voor een AI WhatsApp chatbot met human-in-the-loop functionaliteit.
Hieronder vind je de JSON voor N8N met de AI Whatsapp Chatbot.
De workflow heeft whatsapp als trigger, let op: je hebt een whatsapp business account met een gekoppeld nummer nodig om whatsapp berichten te ontvangen.
De agent bestaat uit een taalmodel en een database. Wij gebruiken vaak een PostgreSQL database voor klanten, maar voor de meeste zal een database in de vorm van Airtable een betere oplossing zijn.
Wanneer de agent de vraag kan beantwoorden ontvangt de vraagsteller direct antwoord via whatsapp.
Wanneer de agent de vraag niet kan beantwoorden wordt een vraag gesteld aan een medewerker. In dit geval is Slack gekoppeld, maar deze kan ook vervangen worden door teams chat, whatsapp, email, telegram of een andere chatapp.
Daarna heeft de werknemer de keuze het antwoord op te slaan in de database en wordt het antwoord naar de vraagsteller gestuurd.
