Frequently Asked Questions

Do I need Meta approval to use the WhatsApp API?

You need a Meta Business account, but Zavu handles the technical integration. We're an official WhatsApp Business Solution Provider, so you can start sending messages in minutes, not weeks.

What's the difference between session and template messages?

Session messages are free-form messages you can send within 24 hours of the customer's last message. Template messages are pre-approved messages you can send anytime to initiate conversations.

How much does it cost?

You pay $0.005 per monthly active contact plus Meta's conversation fees. A typical marketing conversation costs around $0.025 total. This is significantly cheaper than most providers who add large markups.

Can I send marketing messages?

Yes! You can send marketing messages using approved templates. Customers must opt-in first, and you need to follow Meta's commerce and business messaging policies.

How do I handle incoming messages?

Set up a webhook URL and we'll forward all incoming messages in real-time. You can also use our built-in AI agents to automatically respond to customer messages.
