Across Africa, WhatsApp isn't "one channel among many." It's the channel. A customer in Lagos isn't going to fill out a contact form: they want to message you on WhatsApp, right now. The problem is that most online sellers run everything from their personal WhatsApp, on a single phone, and lose track the moment volume picks up.
Connecting WhatsApp Business to your WordPress site solves this — provided you pick the right method. There are three, and they have nothing to do with each other. This tutorial explains them without jargon, then walks through the full connection, step by step.
WhatsApp Business app vs API: the distinction that changes everything
First, we need to clear up a confusion that costs people dearly. "WhatsApp Business" means two very different things.
The WhatsApp Business app (the one you download for free from the Play Store) is built for a solo merchant. One number, one phone, a few quick replies and an away message. It's free and useful at first, but it doesn't really connect to a site: you can't share the inbox with an employee, there's no serious automation, no usable history.
The WhatsApp Business API (Meta's official platform) is built for businesses that want a real shared inbox, automatic replies, and a connection to their site or software. It's what you need once you start receiving dozens of messages a day. You never use the API "by hand": you go through a partner platform that handles the technical side. That's exactly TextDigo's role.
Remember this simple rule: if you're solo and get few messages, the app is enough. As soon as you want to reply at night, share with someone, or stop copy-pasting, you need the API.
The 3 ways to connect WhatsApp to WordPress
1. The wa.me link (the clickable button)
The simplest method. You create a link like https://wa.me/234XXXXXXXXX that, once clicked, opens a WhatsApp conversation with your number. You can even pre-fill a message ("Hi, I'm interested in…").
It's free and takes two minutes. But it's not a real connection: the visitor leaves your site for their WhatsApp app, and everything falls back on your personal number. No automation, no sharing. Fine to start, quickly limited.
2. A "WhatsApp button" plugin
Several WordPress plugins add a nice floating button that does the same thing as the wa.me link, just more presentable. It's cosmetic: it improves the look, but it solves none of the underlying problems (still a single phone, still zero automation).
3. The WhatsApp Business API via a platform (the real connection)
This is where everything changes. By connecting the official API through TextDigo, WhatsApp becomes a channel managed like your WordPress site live chat: a single inbox, several agents, every customer's history, and above all Melia, the AI that answers automatically in English. Here's how to do it.
Tutorial: connect WhatsApp Business to WordPress with TextDigo
What you need before you start
- A TextDigo account (the Free plan is enough to set up).
- A dedicated phone number that is not already used on a regular WhatsApp account. This is the classic mistake: if your number is already on personal WhatsApp, you'll first have to remove it from that account, or use another number. Many online sellers get a new SIM dedicated to the store — it's actually recommended.
- A Meta Business account (Business Manager). If you already manage a professional Facebook page, you probably have one.
The steps
- Sign in to TextDigo and go to the Channels section.
- Add a WhatsApp Business channel. A Meta window opens (the official connection, called Embedded Signup). You authenticate with your professional Facebook account and authorize TextDigo to manage messaging. No technical secret to copy-paste by hand.
- Enter your number and choose to receive the verification code by SMS or voice call. Enter the code you receive, then set a six-digit PIN (Meta requires it to secure the number).
- Let Meta verify your business. This is a Meta step, not a TextDigo one: depending on the country, verification can take from a few hours to a few days. You can set up the rest in the meantime.
- Add the WhatsApp button on WordPress. The TextDigo plugin shows your WhatsApp next to the live chat, so the visitor picks their preferred channel right on the store.
- Activate Melia for WhatsApp: give it your delivery zones, your prices, your payment terms, and it answers WhatsApp messages on its own, day and night.
Once these steps are done, every WhatsApp message lands in your TextDigo inbox, no longer on your personal phone. You can reply from the computer, hand off to an employee, and everything stays tracked.
What you unlock once connected
The real API connection isn't just about convenience. It opens things that are impossible with a simple button:
- A shared inbox. Two or three people answer the same WhatsApp without stepping on each other. No more phone passed from hand to hand.
- Melia answering at night. The peak of messages, in African e-commerce, is the evening. Melia keeps the conversation going at 11 PM, qualifies the need, and leaves you a sale ready in the morning. (I cover the WhatsApp mistakes to avoid in detail in another article — not replying at night is very much one of them.)
- Message templates. An important subtlety: WhatsApp only lets you initiate a message outside a 24-hour window with templates approved by Meta. In practice, to follow up on an abandoned cart or confirm an order, you need an approved template. TextDigo handles creating and sending these templates directly.
- History and contacts. Every customer has their profile, their past exchanges, their orders. You no longer ask "what was your address again?".
How much does it cost?
Two costs to distinguish. First, Meta bills WhatsApp Business conversations on usage, depending on the country and the type of message (rates vary and some service categories are free within a given window). This cost is owed to Meta, regardless of the provider.
Second, the platform. TextDigo bills in FCFA, with a Free plan to start, then Starter at 12,000 FCFA/month and Pro at 35,000 FCFA/month — payable in mobile money (Orange Money, MTN MoMo, Wave, Moov via PawaPay) or by card. No need for an international bank card, unlike foreign solutions.
FAQ
Can you connect WhatsApp Business to WordPress for free?
Yes, partly. A wa.me link or a WhatsApp button plugin is free, but without a shared inbox or automation. Connecting to the official API goes through a platform: TextDigo offers a Free plan to set it up, knowing that Meta bills conversations on usage.
Do you need a different number from your personal WhatsApp?
Yes, it's strongly recommended. The number linked to the WhatsApp Business API can't be active at the same time on the regular WhatsApp app. Most online sellers dedicate a SIM to the store to avoid any conflict.
How long does Meta verification take?
That depends on Meta, not the platform. Depending on the country and the state of your Business account, expect a few hours to a few days. You can set up your live chat and prepare Melia while you wait.
What's the difference between the WhatsApp Business app and the API?
The app is free, built for a solo merchant on one phone. The API is built for businesses: shared inbox, automation, connection to a site and software. As soon as message volume rises, the API becomes essential.
In summary
Putting a WhatsApp button on WordPress takes two minutes, but it only moves the problem: everything still falls back on your phone. The real connection, via the WhatsApp Business API, turns WhatsApp into a managed sales channel — shared inbox, history, and an AI that answers at night.
You can create a free TextDigo account, connect your WhatsApp Business number and install the WordPress plugin today. And if you're new to all this, start by adding a live chat to your store: the two channels are then managed from the same inbox.
