WhatsApp Business API lets you send and receive messages at scale, run broadcast campaigns, build automated flows, and deploy an AI Agent — all on the WhatsApp number your customers already know.WhatsApp Business API is not the same as the regular WhatsApp or WhatsApp Business app. It operates through Meta’s Business Platform and requires a verified WhatsApp Business Account (WABA). Some features, including broadcast messaging to customers who have not messaged you first, require Meta’s approval of your Message Templates before they can be sent.
- A Meta Business Manager account at business.facebook.com
- A phone number that is not already registered on any WhatsApp account (personal or Business app)
- Admin access to your Meta Business Manager
Open the WhatsApp channel settings
In Waply, go to Settings > Channels > WhatsApp and click Connect WhatsApp.
Enter your business phone number
Type the phone number you want to use for WhatsApp Business API. This must be a number that has never been registered on WhatsApp before, or one you have fully deleted from an existing WhatsApp account.
Verify the number
Choose SMS or Voice call to receive your verification code, then enter the 6-digit code in Waply. The number is now registered with Meta.
Connect to Meta Business Manager
Waply will prompt you to log in to Facebook and grant access to your Meta Business Manager. Select the Business Manager account that will own the WhatsApp Business Account, review the requested permissions, and click Continue.Once connected, your WhatsApp number appears as active in Settings > Channels.
If your number was previously used with the WhatsApp Business app, you must delete that account inside the app before registering it through the API. Meta does not allow the same number to be active on both the app and the API simultaneously.

Customize the widget

Waply generates a small JavaScript snippet unique to your widget. Click Copy code to copy it to your clipboard.<script>
window.waplyConfig = {
widgetId: "YOUR_WIDGET_ID"
};
</script>
<script
src="https://cdn.waply.io/widget.js"
async
defer
></script>
YOUR_WIDGET_ID with the ID shown in your Waply dashboard — it is included automatically when you copy the snippet from the settings page. Add the snippet to your website
Paste the snippet into every page where you want the widget to appear. Place it just before the closing </body> tag, or inside the <head> section — both locations work.<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>My Website</title>
</head>
<body>
<!-- your page content -->
<script>
window.waplyConfig = {
widgetId: "YOUR_WIDGET_ID"
};
</script>
<script
src="https://cdn.waply.io/widget.js"
async
defer
></script>
</body>
</html>
If you use a CMS like WordPress, Shopify, or Webflow, paste the snippet into your theme’s global footer or use a “Custom code” section so it loads on every page without editing individual templates.
