How to implement an AI chatbot on WhatsApp Business

WhatsApp has become the preferred communication channel for customers. With over 2 billion active users, integrating an AI agent into WhatsApp Business can multiply your sales team’s efficiency.

Why WhatsApp for customer service

• Ubiquity: Your customers already use it daily
• Immediacy: Direct push notifications
• Multimedia: Send images, documents, locations
• History: Persistent conversations

Requirements for integration

1. WhatsApp Business API

To connect an AI agent, you need access to the WhatsApp Business API, not the regular app. This requires:

• Verified Facebook Business account
• Dedicated phone number
• Authorized Business Solution Provider (BSP)

2. Technical infrastructure

The agent needs:

• Server to process messages
• Connection to language model (OpenAI, Anthropic, etc.)
• Knowledge base with your products/services
• Human escalation system

Flow of a typical conversation

Customer: Hi, I need oil for my Atlas Copco GA55 compressor
    ↓
AI Agent: Queries knowledge base
    ↓
AI Agent: Good morning! For the Atlas Copco GA55 compressor,
          I recommend Repsol Telex 46. We have stock available.
          Would you like me to prepare a quote?
    ↓
Customer: Yes, for 200 liters
    ↓
AI Agent: Generates automatic quote and sends it

Best practices

Initial setup

1. Define the tone: Formal/informal according to your brand
2. Set limits: What topics the agent can handle
3. Design escalation: When to transfer to a human

During operation

• Monitor: Review conversations periodically
• Train: Add new products and FAQs
• Measure: Analyze satisfaction and resolution metrics

Costs and ROI

Concept	Range
Initial setup	500-2,000 EUR
