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:

1. Receives customer queries through a webhook endpoint
2. Processes natural language requests using Google Gemini AI
3. Automatically checks domain availability via WHMCS DomainWhois API
4. Provides verified, accurate responses with available alternatives
5. 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.
