What the WhatsApp Business API is for
The WhatsApp Business API is designed for companies that need to send and receive messages at a scale the regular WhatsApp Business app cannot support — think order updates, appointment reminders, and support conversations handled by a whole team rather than one phone.
Unlike the consumer app, access goes through an approved Business Solution Provider, which is also what gives you multi-agent support, automation, and CRM integration.
Template messages vs. session messages
Template messages are pre-approved formats you can send outside a 24-hour customer-initiated window — order confirmations and reminders are common examples. Session messages are free-form replies allowed only within 24 hours of the customer's last message.
- Template messages require Meta approval before use.
- Session messages can be conversational and dynamic.
- Mixing both correctly is what makes a support flow feel natural.
Verification and sending limits
New numbers start with a limited daily conversation cap that increases as your quality rating and usage history improve. Getting the Green Tick business verification is optional but improves customer trust.
Planning a rollout that customers engage with
Businesses that succeed with WhatsApp usually start narrow — one use case, one team — before expanding. Support and order updates tend to have the highest opt-in and read rates.
Start with the conversation your customers are already trying to have with you — most support tickets are really just status questions.
