WhatsApp Business API

Why it matters

Owners often use "WhatsApp Business" for two different things. The free WhatsApp Business app is built for one small team on a phone. The WhatsApp Business Platform (the API, including the Cloud API hosted by Meta) has no screen of its own: you connect it to software, usually through a business solution provider or your own build, and that software provides the inbox, automation and reporting. It is the route for many agents on one number, chatbots, CRM integration, and campaigns that are not copy-pasted by hand.

For businesses where customers already live on WhatsApp, this is where speed to reply, reminders and follow-up get automated.

The rules that shape it

• Opt-in. You message people who have agreed to hear from you on WhatsApp.
• The 24-hour window. After a customer messages you, you can send free-form replies for 24 hours. Outside it, you can only send pre-approved template messages.
• Templates. Reusable messages, such as an appointment reminder, that Meta reviews and categorises (utility, marketing, authentication).
• Pricing. Meta charges per message, only when it is delivered, and rates vary by message category (marketing, utility, authentication) and the recipient's country. They are published on its pricing page, which also lists the free cases. Since 1 October 2026, service replies within the window are free only for the first 1,000 a month per number. Software providers add their own fees.

How to start

1. List the three messages that would help most: first reply, reminder, follow-up.
2. Pick a provider or CRM that connects to the Platform and lets you export your chats and contacts.
3. Register your business and number, write templates, and test with staff.
4. Route replies to a person quickly; automate the routine, not the relationship.

Common mistakes

• Buying lists and blasting them. Quality ratings drop and your number can be restricted.
• Using one template for everything.
• No handover to a human.
• Leaving chats outside the CRM, so nobody can see which messages led to sales.
