WhatsApp Business API

The WhatsApp Business API, without writing code

The API is the part of WhatsApp that software plugs into. It has no screen of its own, so you use it through what's built on top: our shared inbox, flows, and campaigns all run on it. You connect your number through Meta's sign-up flow, and the WhatsApp Business app on your phone keeps working.

Where the free app runs out

WhatsApp Business app

  • Free, on one phone plus up to 4 linked devices.
  • Broadcast lists only reach people who saved your number.
  • There's no telling which teammate already helped a customer.
  • Your store, calendar, or CRM can't talk to it.

WhatsApp Business API

  • Your whole team replies from one inbox, on the same number.
  • Flows handle routine questions and reminders, evenings included.
  • Campaigns reach everyone who opted in, and you can see who read each message.
  • Zapier and webhooks tie WhatsApp into the rest of your tools.

Meta provides the connection. The inbox, flows, and campaigns you actually work in are ours.

Setup

How your number gets on the API

1

Create an account

Free for 30 days, no credit card. You'll be in the dashboard within minutes.

2

Connect your number

Start from the dashboard and finish in Meta's own sign-up flow. We're a Meta Tech Provider, so there's no developer application to file. Your current number works, and the app on your phone stays.

3

Add a payment method at Meta

Meta bills you directly for the messages you start. The payment method sits on your own WhatsApp Business account.

4

Send your first message

Reply to a customer from the inbox, or submit a template for messages you start. Meta usually approves one within minutes to a few hours.

Pricing

What the API costs

Since July 1, 2025, Meta has charged per message you start, with a separate rate for each message type. You pay Meta directly, and we don't add a cent. The software itself is a flat monthly fee.

FAQ

WhatsApp Business API questions

It's the interface software uses to send and receive WhatsApp messages and to track whether they arrived. Meta calls the whole offering the WhatsApp Business Platform, and the API is how you connect to it. It has no screen, so you always reach it through software.
