WhatsApp Business API is the version of WhatsApp built for companies that serve many customers. Unlike the regular app or WhatsApp Business on a single phone, the API supports multiple agents, integrations, templates and automation.
API vs the regular app
- Regular / Business app: a single device, manual handling, no integrations.
- WhatsApp Business API: multiple agents in one inbox, approved templates, bots, and a connection to your CRM or platform.
What it is used for
Customer support, appointment and payment confirmations, notifications, OTP codes and campaigns. With a flow bot you can automate answers 24/7 and hand off to an agent when needed.
Templates and opt-in
To start conversations (outside the 24-hour window) you use templates approved by Meta. And you always need the customer's opt-in to message them. All of this is managed from the platform.
How to get started
You need an enabled number and a WhatsApp Business account. At TelHarbor we set it up and connect it to your inbox. See the Business WhatsApp page.
Frequently asked questions
Can I use my current number?
In many cases yes, if the number is not already in the WhatsApp app; it gets enabled for the API.
How many agents can handle it?
Several at once, from a single inbox, with the history of each conversation.
Can it be automated?
Yes. With menus, flow bots and auto-replies, with handoff to an agent.
