How It Works

Embedded Chat Interface:

Generates embeddable HTML code that creates a chat widget on any website
Provides both hosted and embedded modes for different use cases
Handles all communication between website visitors and the AI system

Intelligent Conversation Management:

Uses sophisticated system prompts to maintain context about your business
Handles common inquiries about services, pricing, and company information
Gracefully redirects off-topic conversations back to business matters

Smart Calendar Integration:

Connects to Google Calendar to check real-time availability
Automatically suggests meeting times based on your schedule

Meeting Booking Process:

Validates meeting requests against existing calendar entries
Confirms all details with users before creating calendar events

Required Setup Configuration

System Message Requirements: Your AI agent needs a comprehensive system message that includes:

Business Identity: Company name, services, location, timezone
Business Context: What you offer, pricing information, key differentiators
Conversation Rules: How to handle inquiries, booking procedures, moderation guidelines
Personality Instructions: Tone of voice, response style, conversation length preferences

Example System Message Structure:

You are a helpful, intelligent website chatbot for [Company Name], a [business type]. The current date is [dynamic date]. You are in the [timezone] timezone.

Business Context:

We offer [services] with [key benefits]
Our pricing is [pricing structure]
We work with [target customers]

Your task is answering questions about the business & booking meetings. For meetings: use calendar function to check availability, collect name/email/preferred time, confirm details.

Rules:

Keep responses short and conversational
Stay focused on business topics
Always confirm timezone when discussing meeting times

Google Calendar Setup:

Enable Google Calendar API in Google Cloud Console
Create OAuth2 credentials for N8N
Connect your business calendar in the Google Calendar nodes
Set correct timezone in both nodes to match your business location

Website Integration:

Switch chat trigger to "embedded" mode
Copy the provided CDN embed code
Paste code into your website's HTML (before closing body tag)
Replace webhook URL with your production URL

Business Use Cases

Service Businesses - Automate initial consultations and lead qualification
Agencies - Handle project inquiries and schedule discovery calls
Consultants - Streamline the booking process for potential clients
E-commerce - Provide product support and schedule demos
Any Business - Replace contact forms with intelligent conversation

Revenue Potential

This system can replace expensive chatbot services that cost $100-500/month. The automated booking feature alone typically increases meeting conversion rates by 40-60% compared to traditional contact forms.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
