Do I need a WhatsApp Business API account?

Yes. To use AI-powered automation, you need access to the WhatsApp Business API (not the regular WhatsApp Business app). We help you set this up as part of onboarding.

Can the agent send images and documents?

Yes. Your agent can send product images, PDFs, location pins, and contact cards, all the rich media formats WhatsApp supports.

What happens outside the 24-hour window?

After 24 hours of customer inactivity, your agent uses pre-approved message templates to re-engage. We handle template creation and Meta approval for you.

Is WhatsApp automation expensive?

WhatsApp Business API charges per conversation (not per message). Costs vary by country but are typically $0.02-0.08 per conversation. Our pricing is separate from Meta's API fees.

Can I use my existing WhatsApp number?

Yes, in most cases. You can migrate your existing WhatsApp Business number to the API. Note that you cannot use the same number on both the Business app and the API simultaneously.

How does the agent handle multiple languages?

Your agent can detect and respond in the customer's language automatically. It supports 95+ languages out of the box, which is especially useful for businesses serving international customers on WhatsApp.

Why WhatsApp Is Your Most Powerful Channel

WhatsApp is the world's most popular messaging app with over 2 billion monthly active users across 180+ countries. For small businesses, it is not just a chat app. It is the primary way customers expect to communicate.

Messages sent on WhatsApp have a 98% open rate compared to 20% for email. Response rates are 5x higher than SMS. In markets like Latin America, Southeast Asia, and Europe, customers actively prefer WhatsApp over phone calls and email.

With WhatsApp Business API, you can automate conversations at scale while maintaining the personal, conversational tone that customers love. An AI agent on WhatsApp turns every message into an opportunity to qualify, convert, and delight.

WhatsApp Business API Compliance

WhatsApp Commerce Policy

WhatsApp prohibits certain industries (gambling, alcohol, tobacco) and requires all businesses to comply with their Commerce Policy and Business Terms of Service.

24-Hour Messaging Window

WhatsApp enforces a 24-hour customer service window. After 24 hours, you can only send pre-approved message templates, not free-form messages.

Opt-In Requirements

Customers must explicitly opt in before receiving messages from your business. You cannot send unsolicited messages or buy contact lists.

Message Template Approval

Outbound message templates must be submitted to Meta for approval before use. Templates with promotional content face stricter review.

End-to-End Encryption Expectations

WhatsApp users expect end-to-end encryption. Business API messages are encrypted in transit, but stored data must also be secured to maintain user trust and meet data protection standards.
