1. Overview & Demonstration

The video demonstrates a fully automated lead generation and appointment booking system for a medical spa ("Marina Glow Metspa"). The system utilizes a website built with Google Gemini, integrated with a Naden workflow, and powered by a voice agent created using Retail AI and GPT Realtime. The demonstration shows a user submitting a consultation request on the website, triggering a phone call from the AI-powered voice agent ("Cindy") to confirm the request and book an appointment. The entire process is presented as a replicable solution for businesses and a potential service offering for AI automation experts.

2. Website Creation with Google Gemini

The Metspa website was created using Google Gemini’s AI Studio. The entire website was generated from a single prompt: “build a modern premium onepage website from a San Francisco Metspa called Marine Glow Metspa.” The speaker emphasizes the ease of use and the ability to quickly generate a professional-looking website with minimal coding. The key is to ensure the prompt specifies that submitted data (name, email, phone number, service) should be sent to Naden via a webhook. A screenshot of the prompt is encouraged for viewers to replicate the process.

3. Naden Workflow & Webhook Integration

Naden serves as the central hub for connecting the website to the Retail AI voice agent. When a user submits the consultation form on the website, the data is sent to Naden via a webhook. The webhook URL is copied from the Naden workflow and pasted into the Google Gemini website code. Naden then extracts the user’s information (full name, email, phone number, service requested) and sends it to the Retail AI voice agent via an HTTP request. The speaker highlights the importance of replacing the default Naden URL with the user’s specific Naden app account URL. The workflow also includes an optional step to update a Google Sheet with the lead information.

Data Flow: Website Form Submission -> Webhook -> Naden -> Retail AI Voice Agent & Google Sheets (optional).

4. Retail AI Voice Agent Configuration

The voice agent, named "Cindy," is built within the Retail AI platform. The core of the agent is a detailed prompt outlining its role, personality, and step-by-step instructions for interacting with potential clients.

Key Prompt Elements:

• Role Definition: "You are Cindy, AI powered voice assistant for Marina Glow Met Spa…"
• Goal: "…to follow up when people submit consultation forms to confirm their service and help them book an appointment."
• Step-by-Step Instructions: The prompt provides a detailed script for the conversation, including greetings, service confirmation, appointment scheduling, and contact information verification.
• Dynamic Variables: The prompt utilizes placeholders (e.g., name, service requested) that are dynamically populated with data received from Naden.
• Function Calls: The prompt instructs the agent to use specific Retail AI functions, such as check availability calendar and book appointment calendar, to interact with Cal.com for appointment scheduling.

The speaker emphasizes the importance of accurately naming the functions to ensure proper integration with Cal.com. Cal.com integration requires an API key and event ID. The agent also includes an end call function for polite call termination.

5. GPT Realtime & Voice Quality

The voice agent leverages GPT Realtime, which the speaker identifies as the best model for voice applications due to its low latency and lack of awkward delays. The cost is approximately $0.125 per minute.

6. Real-World Results & Community Resources

The speaker highlights the success of community members utilizing similar voice agent automations. Isaac recently closed a client, and Lib has secured a $22,000 deal with a $1,500 monthly retainer. Retail AI offers a certification program that lists certified partners on their website, providing lead generation opportunities.

7. Technical Details & API Integration

The Retail AI agent ID is crucial for connecting the Naden webhook to the correct agent. This ID is used in the HTTP request sent from Naden to Retail AI. The speaker demonstrates how to copy the agent ID from Retail AI and paste it into the Naden workflow. The API endpoint used is V2 create a phone call.
