If you're thinking about moving your WhatsApp selling to the official API, the first question is simple: how much will it cost me in naira?
WhatsApp Business API pricing in Nigeria works per message. Meta charges for each message your business delivers, and the price depends on what kind of message it is. A promotional broadcast costs far more than an order confirmation, and some messages are free.
This guide explains Meta's pricing model as of November 2026, the current rates for Nigerian numbers, a worked naira example, and what's free. We also explain how the API fits with a tool like Serlzo, where your plan and Meta's message fees are two separate things.
How does WhatsApp Business API pricing work?
Since July 1, 2025, Meta has charged per delivered message, not per conversation. Meta's developer documentation sets out the basics:
- You pay only for delivered messages. A message that fails isn't charged.
- Messages people send you are free. Meta only charges for business-to-customer messages.
- The rate depends on two things: the message category, and the country code of the person receiving it. Messaging a +234 number uses Nigeria's rate.
- Rates change only on set dates. Meta now updates prices only on January 1, April 1, July 1 or October 1, with at least a month's notice for rate changes.
The four message categories
Every message your business sends falls into one category, and carries one charge.
Template messages (pre-approved by Meta, can be sent at any time):
- Marketing. Promotions, launches, offers, "the early-bird price ends tonight".
- Utility. Transactional updates, like a payment receipt or "here's your course access link".
- Authentication. One-time passcodes for logging in.
Non-template messages (free-form, only within 24 hours of the customer's last message):
- Service. Normal replies to a customer who messaged you, typed by you or written by a third-party AI.
There's also a fifth category, Meta Business Agent, for replies written by Meta's own AI agent. Meta prices it per token, not per message. Most creators won't use it, so we'll leave it aside.
WhatsApp Business API pricing in Nigeria: the current rates
These are Meta's list rates in US dollars for messages delivered to Nigerian (+234) numbers. We took them from Meta's official rate calculator on its WhatsApp Business website in November 2026. Meta's developer docs say the current rate card took effect on October 1, 2026, and Nigeria wasn't on the list of markets that changed that day.
| Message category | Rate per delivered message (USD) | About in naira* |
|---|---|---|
| Marketing | $0.0516 | ₦70 |
| Utility | $0.0067 | ₦9 |
| Authentication | $0.0067 | ₦9 |
| Authentication (international) | $0.075 | ₦101 |
| Service | $0.0067, after 1,000 free a month per number | ₦9 |
*Naira figures use about ₦1,350 to $1 and are rounded. Meta bills in your account's currency, so your real naira cost depends on your card's or bank's exchange rate on the day.
A few notes on the table:
- Marketing is the expensive one. It costs about eight times more than utility.
- Utility and authentication get volume discounts. In Nigeria the utility rate falls to $0.0064 after 100,000 messages in a month, and lower again at higher volumes. Very few creators will reach those levels.
- Authentication-international only applies to very large senders (Meta's threshold is more than 750,000 messages in 30 days across these markets) that are based outside Nigeria and message Nigerian users. A Nigerian creator won't pay it.
A worked example: what 1,000 marketing messages cost in naira
Say you're launching a ₦25,000 course and want to tell 1,000 past buyers and leads on WhatsApp.
- Launch announcement: 1,000 marketing messages × $0.0516 = $51.60, about ₦69,700.
- Payment receipts for 40 buyers: 40 utility messages × $0.0067 = $0.27, under ₦400.
- Replies to 150 people who asked questions: 150 service messages. If that number hasn't used its 1,000 free service messages this month, ₦0.
Total Meta fees: about $51.87, roughly ₦70,000. If 40 people buy at ₦25,000, that's ₦1,000,000 in sales from a ₦70,000 message bill.
Only delivered messages count. If 1,000 people are on your list but 900 receive it, you pay for 900.
For comparison, a 5,000-person launch would cost about $258 (around ₦348,000) in marketing messages alone. That's why it pays to send to engaged, opted-in contacts instead of everyone you've ever collected.
Is WhatsApp Business API free?
Not entirely. Meta's pricing page doesn't list a subscription fee for the API itself; you pay per delivered message. But some messages cost nothing:
- Messages customers send you. Always free.
- The first 1,000 service messages each month, per business phone number. Unused messages don't roll over.
- Messages sent after someone reaches you through a Click-to-WhatsApp ad. If a person messages you from a Facebook or Instagram ad that clicks to WhatsApp (on the Android or iOS app) and you reply within 24 hours, Meta opens a free entry point window. Meta's developer docs say it can stay open for up to 7 days, and marketing, utility, authentication and service messages in that window are free.
What changed on October 1, 2026
If you read older guides, you'll see "service messages are free" and "utility replies are free". That was true until September 30, 2026. Meta's developer documentation says that from October 1, 2026:
- Service messages are charged again, after the 1,000 free per number each month.
- Utility templates sent inside an open 24-hour window are charged at the normal utility rate. They had been free since July 2025.
Where Meta's own pages disagree
When we checked in November 2026, Meta's WhatsApp Business marketing website still said service messages and utility replies aren't charged, and described a 72-hour free window for ad clicks. Meta's developer documentation, updated for October 1, 2026, says service messages are charged after 1,000 a month and the ad window lasts up to 7 days.
We've followed the developer documentation, because it's the more detailed and more recently updated source. But this is exactly the kind of detail that changes, so check Meta's pricing documentation before you plan a big campaign.
How does WhatsApp Business API work?
In plain terms:
- You get a dedicated business number registered on Meta's WhatsApp Business Platform, linked to a Meta business portfolio.
- You connect it to a tool (like Serlzo) that sends and receives messages through Meta's Cloud API.
- To start a conversation, you use a template that Meta has approved.
- When a customer replies, a 24-hour window opens in which you can send normal free-form messages.
- Meta controls volume with messaging limits. New businesses can message 250 unique people per 24 hours outside those windows, rising to 2,000 after business verification and up to unlimited with good quality. Our WhatsApp broadcast limit guide explains the tiers.
- Meta bills its message fees. Meta's documentation says businesses need a payment method on their WhatsApp business account once they go beyond free messages.
How to get WhatsApp Business API with Serlzo
You don't need a developer. In Serlzo:
- Get a dedicated number that isn't on any WhatsApp account: a new SIM, or a VoIP number from Twilio or Termii.
- Go to Integrations and choose the WhatsApp Business API. Serlzo uses Meta's Embedded Signup, so you log in with Facebook and connect your Meta business account in a few screens.
- Verify the number. It takes about 2 to 5 minutes.
- Create your templates (Marketing, Utility or Authentication) and submit them. Meta's review can take up to 24 hours.
- Send broadcasts and run workflows to a CRM list, product customers or community members, with sent, delivered, read and failed stats.
Serlzo's price vs Meta's price
These are two separate bills, and it's worth being clear about which is which.
| What it pays for | How much | |
|---|---|---|
| Serlzo plan | The software: broadcasts, workflows, AI chatbot, CRM, storefront, communities | Free plan at ₦0; WhatsApp Marketing from Basic at $13 (about ₦17,500) a month |
| Meta's message fees | Delivering your WhatsApp messages | Per delivered message, at the rates above |
WhatsApp Marketing and workflows are on Serlzo's paid plans, starting with Basic. If you turn on the AI chatbot's smart replies, those use AI credits or your own Groq, Claude or OpenAI key.
Is the official API worth it for a small creator? If you have under a couple of hundred customers who've all saved your number, the free WhatsApp Business app may be enough. Once you're sending launches to hundreds or thousands, the API's reach and safety usually justify ₦70 a marketing message.

How do I get WhatsApp Business API?

Know your costs before your next launch
A ₦70 marketing message to a buyer who asked for your updates is cheap compared with a sale you'd otherwise miss, even if they never saved your number. The trick is sending the right category to the right people.
Connect the official API in Serlzo, build your first template, and send a test broadcast to a small CRM list before your next launch.
