The WhatsApp Business API is Meta's official way for software to send and receive WhatsApp messages on a business's number. It is what a chatbot, CRM or AI agent connects to. Unlike the free WhatsApp Business app, it is not an app you open, it costs money per message, and in Kenya most businesses get it through a provider rather than directly from Meta.
WhatsApp Business app vs the WhatsApp Business API
| Business app | Business API | |
|---|---|---|
| Cost | Free | Meta charges per message, plus the provider's fee |
| Who replies | A person typing on a phone | Software: a chatbot, AI agent or CRM, with people taking over when needed |
| Automation | Greeting, away message, fixed quick replies | Replies that read the question, follow-ups, reminders, campaigns |
| Messaging many customers | Broadcast lists, only to people who saved your number | Approved templates to customers who opted in, within Meta's daily limit |
| Setup | Download from the Play Store | A Meta Business account and a number connected through a provider |
What the WhatsApp Business API costs in Kenya
Meta bills per delivered message, priced by the message's category and the customer's country. Kenya falls in Meta's Rest of Africa market:
- Marketing messages (offers, win-back campaigns): USD 0.0225, about KES 2.90 each.
- Utility messages (order updates, receipts, reminders): USD 0.0040, about KES 0.52 each.
- Service messages (your replies within 24 hours of a customer messaging you): free until 30 September 2026, then USD 0.0040, about KES 0.52 each.
That is Meta's fee only. The provider you connect through adds its own setup and monthly charges, and for a small business those are usually the bigger number. The full breakdown, with a worked example, is in WhatsApp Business API pricing in Kenya.
How to get the WhatsApp Business API in Kenya
Applying to Meta directly means business verification, App Review and, to serve other businesses, Tech Provider status. That takes weeks. Most Kenyan businesses go through a provider that has already cleared those steps:
- Pick a provider. Compare them on the monthly fee and on what the software does with the messages, since Meta's per-message rate is the same everywhere.
- Complete Meta's signup through the provider's link. You log in with Facebook, create or pick your Meta Business account, and add your number.
- Verify the number. Any Kenyan number that can receive an SMS or a voice call works, Safaricom, Airtel or Telkom.
- Attach a payment method in Meta Business Manager, so template and service messages keep being delivered.
- Get your templates approved. Any message you start, rather than reply to, has to use a template Meta has reviewed.
Can I keep using WhatsApp on my phone?
Often, yes. Some providers connect your existing WhatsApp Business app number in a mode that keeps the phone app working alongside the API, so your chat history and your habit of replying from your phone both stay. Connecting in API-only mode moves the number off the phone app entirely. Ask which one a provider uses before you connect.
Limits to know about
- The 24-hour window. You can reply freely for 24 hours after a customer's last message. After that, only an approved template can reopen the chat.
- Daily limit. Meta caps how many different people you can start conversations with in 24 hours. It usually starts at 250 and rises as your business verifies and keeps a good quality rating. See how to send bulk WhatsApp messages.
- Template quality. If customers block or report a marketing template, Meta pauses it.
