WhatsApp Business API for Your Business

CampaigningTool is a WhatsApp Business API provider for businesses that want to message customers at scale. You connect your own number through Meta, send updates and offers to customers who opted in, reply from a shared inbox, add an AI agent, and connect your own software. Most businesses finish the Meta connection in about 10 minutes.

About the API

What Is the WhatsApp Business API?

The WhatsApp Business API is the version of WhatsApp that Meta gives to companies that want to message customers at scale. It has no app of its own. You use it through a platform like CampaigningTool, which gives you a dashboard, a team inbox and tools for sending campaigns.

It's different from the free WhatsApp Business app. The app works for a small shop with one phone. The API is for businesses that have a team, many customers, or software that needs to send and receive messages on its own.

A WhatsApp Business API provider is a company that gives you access to the API through a dashboard, a team inbox and tools for campaigns. CampaigningTool is one. You keep your own number and your own customer list, and you pay a plan fee plus Meta's message charges.

Pricing Breakdown

How Much Does the WhatsApp Business API Cost?

Clear, transparent pricing structure with zero hidden markups.

There are two parts to the cost:

1. Meta's message charges

Meta charges for messages by category (marketing, utility, authentication). We pass these on at Meta's rate with no markup. Meta changes its rates from time to time, so check Meta's current rate card before you plan a budget.

2. Your CampaigningTool plan

This is a monthly or yearly fee plus 18% GST, and it covers the dashboard, team inbox and tools. See the pricing page for current plans.

Frequently Asked Questions About WhatsApp Business API

Everything you need to know about API pricing, accounts, sending limits, and setup.

No. Meta charges for most business messages, and the platform you use has its own plan. Replies to customers inside Meta's service window have been free, but Meta can change this, so check its current rate card.

The app is for a small business using one phone. The API is for teams, bulk messaging and automation. You use it through a platform like CampaigningTool.

Often yes, but the number must meet Meta's requirements. Read our guide to use your existing number on the WhatsApp API.

The account connection takes about 10 minutes. Meta's business verification and template approval take extra time and are decided by Meta.

You can start without it, but your sending limits will be low. Verifying your business raises them.

Yes, to people who agreed to hear from you, using templates approved by Meta. See our bulk WhatsApp message broadcast page.

Yes. The team inbox lets many agents answer from the same number.

No. Meta decides who gets it. We can help you apply.

Ask each provider four things: what you pay besides Meta's charges, whether they add a markup to Meta's message fees, how many agents your plan includes, and what happens to your data and number if you leave. Then test the dashboard in a free trial before you commit. See our pricing page for how we answer those questions.
