Domain Availability Checker Chatbot with Google Gemini and WHMCS

Description

This n8n template implements a Chatbot with Google Gemini to Check Domain Name Availability using the WHMCS API

Who's it for

This template is designed for domain registrars, web hosting companies, and IT service providers who use WHMCS (Web Host Manager Complete Solution) and want to offer automated domain availability checking to their customers. It's perfect for businesses looking to enhance their customer support with AI-powered domain search assistance.

How it works / What it does

This workflow creates an AI-powered customer support chatbot that automatically checks domain name availability using WHMCS API integration. When customers ask about domain availability, the AI agent:

Receives customer queries through a webhook endpoint
Processes natural language requests using Google Gemini AI
Automatically checks domain availability via WHMCS DomainWhois API
Provides verified, accurate responses with available alternatives
Maintains conversation context throughout the session

The system ensures 100% accuracy by only suggesting domains that have been verified as available, eliminating guesswork and improving customer trust.

How to set up

1. Configure WHMCS API Credentials
Replace Your_WHMCS_Identifier with your actual WHMCS API identifier
Replace Your_WHMCS_Secret with your actual WHMCS API secret
Update https://your_whmcs_url.com/includes/api.php with your WHMCS domain

2. Set up Google Gemini API
Configure your Google Gemini API credentials in the Google Gemini Chat Model node
Ensure you have sufficient API quota for your expected usage

3. Deploy the Webhook
The workflow creates a unique webhook endpoint for receiving customer queries
Use this endpoint URL in your customer-facing application or chat interface

4. Test the Integration
Send a test query to verify domain checking functionality
Ensure proper error handling and response formatting
