Use the WhatsApp Business app if one or two people handle chats and you only need basics like quick replies and away messages. Use the WhatsApp Business Platform (the API) through an official provider when you need automation, several agents on one number, or a link to your CRM.

## The two products

The **WhatsApp Business app** is a free app on your phone built for small businesses. It adds a business profile, catalogue, labels, quick replies and away messages.

The **WhatsApp Business Platform**, often just called the API, lets software send and receive WhatsApp messages. You use it through an official provider or Meta's own cloud service, with your own backend or a provider's inbox.

## Comparison

| | Business app | Business Platform (API) |
|---|---|---|
| Cost to start | Free | Provider and messaging costs |
| Who answers | One person on a phone, with limited linked devices | Many agents through an inbox or your own system |
| Automation | Quick replies, greeting and away messages | Full chatbots, workflows, notifications |
| CRM integration | None built in | Yes, through software |
| Bulk and template messages | Limited | Supported within WhatsApp's rules |
| Setup | Minutes | Days to weeks, including business verification |

## When to switch to the API

- Messages arrive faster than one phone can handle.
- Several people need to answer from one number.
- You want leads saved to a CRM automatically.
- You want a chatbot or automated reminders.

## Things to check before you switch

1. **Number handling.** A number on the API generally cannot also be used in the regular app, so plan which number to use.
2. **Pricing.** Message charges depend on current rules and categories, so check before budgeting.
3. **Consent and templates.** You need customer consent and approved templates to message outside the reply window.
4. **Provider choice.** Look at pricing, support, inbox quality and integrations.

## Our view

Start with the Business app and a [chat link](/blog/whatsapp-click-to-chat-link). Move to the API when the pain is clear. Then design the flows around your leads, as covered in the [complete WhatsApp chatbot guide](/blog/whatsapp-chatbot-for-business-guide).

## FAQ

### Is the WhatsApp Business API free?
No. The platform and providers charge, and WhatsApp charges for certain message types. Check current pricing.

### Can I use both the app and the API on one number?
Generally no, so plan your number setup. Ask your provider about current options.

### Do I need a developer for the API?
For basic use, a provider's inbox is enough. For custom flows, AI or CRM integration, you need development.

### Is the Business app good enough for a small shop?
Often yes. If you are handling a few chats a day, it is enough.
