How to Build a WhatsApp AI Agent Using WASheet — Step-by-Step Guide

 

Step 1: Install WASheet Browser Extension

The first step is installing WASheet on your browser. Here’s how:

1. Visit washeet.com
2. Click on “Install for Free” this takes you directly to the Chrome Web Store.
3. Click “Add to Chrome” or “Get” and confirm the installation
4. Once installed, open WhatsApp Web at web.whatsapp.com
5. Sign in with your Gmail account to activate your WASheet session
6. The WASheet panel will now appear inside your WhatsApp Web interface, ready to use

Pro Tip: WASheet recommends using Microsoft Edge for the best performance and most stable experience. iPhone users should note that WASheet works with WhatsApp Business on iOS, not the personal WhatsApp app.

That’s it WASheet is now live inside your WhatsApp Web. No developer tools, no API configuration, no backend setup. Just install and go.

Step 2: Navigate to Agentic AI Workflows

Inside the WASheet panel on WhatsApp Web, browse through the available features and navigate to “Agentic AI Workflows”.

Click “Open” to enter the workflow builder, then click on “AI Agent” to open the main AI Agent control panel.

This is your command center where you’ll configure, launch, monitor, and manage your WhatsApp AI Agent from start to finish.

Step 3: Select Your AI Provider and Add API Key

Inside the AI Agent panel, you’ll find an “AI Provider” section with two-tab options:

• Claude — by Anthropic (exceptional instruction-following, ideal for structured business flows)
• OpenAI — GPT models (widely used, great for general-purpose conversational AI)

Select the AI provider of your choice and paste in your API key to connect the intelligence layer to your WhatsApp AI Agent.

Both providers are excellent. Claude tends to excel at following detailed business-specific prompts with precision, making it particularly effective for appointment scheduling flows, multi-step data collection, and nuanced customer interactions. OpenAI’s GPT models are equally capable and widely familiar to businesses already using the OpenAI ecosystem.

Once your API key is in, your WhatsApp chatbot is connected to a powerful large language model (LLM) and ready to hold natural, intelligent conversations with your customers.

Step 4: Upload Your Business Reference Data (Excel File)

This is where your AI Agent gains business-specific intelligence. Under the “Upload Reference File” section, upload any Excel spreadsheet (.xlsx) that contains your business data.

Your AI Agent will read, learn from, and reference this file when responding to customer queries on WhatsApp.

Examples of reference data you can upload:

Business Type	Reference File Data
Dental / Medical Clinic	Doctor schedules, appointment slots, treatment list, pricing
Restaurant	Food menu, prices, daily specials, dietary options
Hotel / Guest House	Room types, availability, rates, amenities, check-in info
Gym / Fitness Studio	Class schedules, trainer availability, membership plans
E-commerce Store	Product catalog, descriptions, pricing, stock availability
Law Firm	Services offered, consultation slots, lawyer profiles
Salon / Spa	Service menu, pricing, stylist availability, packages
Real Estate Agency	Property listings, visit slots, agent contact details

For example, if you operate a dental clinic and a patient message your WhatsApp asking, “Is Dr. Ahmed available for a root canal on Thursday afternoon?” your AI Agent will check the uploaded schedule and respond with accurate, real-time information pulled directly from your Excel file.

This data-awareness is what makes WASheet’s WhatsApp AI Agent genuinely intelligent, not just scripted.

Step 5: Write Your AI Agent Prompt (The Most Important Step)

The “WASheet AI Prompt” section is the soul of your entire WhatsApp AI Agent. This is where you define your AI’s identity, behavior, conversation flow, and goals.

Think of your AI prompt as a detailed job description for a new employee. The more thoroughly you write it, the better and more reliably your AI Agent will perform.

A high-quality WhatsApp AI Agent prompt should include:

1. Business Introduction: Your business name, type, location, operating hours, and contact info
2. Agent Role: What the AI is meant to do (book appointments, take orders, answer FAQs, collect leads)
3. Conversation Flow: Step-by-step sequence the AI should follow when chatting with a customer
4. Data Collection Requirements: What information to collect (name, phone number, date, service type, etc.)
5. Language & Tone: Formal or friendly, English only or multilingual (Urdu, Arabic, Hindi, etc.)
6. Confirmation Messages: How the AI confirms a completed booking, order, or inquiry
7. Edge Case Handling: What to say when a question is outside the AI’s scope

Sample AI Prompt (Dental Clinic):

“You are a professional appointment booking assistant for [Clinic Name], a dental clinic located in [City], operating from Monday to Saturday, 9 AM to 7 PM. Your job is to help patients book appointments. Ask for the patient’s full name, WhatsApp number, preferred doctor, treatment type, and desired date and time. Cross-reference the uploaded schedule to confirm availability. Once confirmed, summarize the appointment details clearly and thank the patient. Keep your tone warm, professional, and concise.”

The golden rule: the more precise and detailed your AI prompt, the more accurate, consistent, and professional your WhatsApp AI Agent’s responses will be.

You can find ready-made AI prompt templates for all major business categories clinics, restaurants, gyms, hotels, e-commerce stores, law firms, and salons on the WASheet website’s prompt guide section.

Step 6: Set Your Admin Notification Number

In the “Admin Notification Number” field, enter your WhatsApp number or a team member’s number.

Every time your AI Agent successfully collects and finalizes customer data whether it’s an appointment, a food order, or a lead it will automatically send the complete structured summary to this WhatsApp number.

This feature works as:

• A real-time business alert system on WhatsApp
• A backup data channel when you’re not actively monitoring WhatsApp Web
• A team notification tool to keep admins, managers, or support staff instantly informed

You’ll never miss a customer interaction or booking again the AI Agent handles the conversation and your phone gets the summary automatically.

Step 7: Launch Your WhatsApp AI Agent

Once all configuration is complete AI provider, API key, reference file, AI prompt, and admin number click the “Start Agent” button.

You’ll see the “Agent Running” status appear, confirming your WhatsApp AI Agent is now live, active, and handling real customer conversations automatically.

To pause or stop the agent at any time, simply click “Stop Agent”.

That’s your fully functional, no-code WhatsApp AI Agent live in under 60 seconds.

How to View and Manage AI-Collected Data

All data collected by your AI Agent is accessible through the Bell Button (Notification Panel) inside WASheet.

From there you can:

• View all collected records in a clean, structured table format

• Download your data in your preferred format:
