Overview

WhatsApp Calling is a feature of the WhatsApp Business Cloud API that enables businesses to conduct voice calls (VoIP) directly through WhatsApp.

It supports two call types:

• Inbound calls: customer → business

• Outbound calls: business → customer

Pricing

Inbound Calls

• Free — regardless of whether the business answers the call.

Outbound Calls

• Charged based on connected call duration.

• Billing unit: every 6 seconds (rounded up to 6 seconds).

• The rate depends on the country code of the customer’s phone number.

Example:

Indonesia rate: 0.0242 USD / 6 seconds

If a business places a call to an Indonesian user and ends the call after 10 seconds:

→ Billing = 2 units × 0.0242 USD = 0.0484 USD

User-Initiated Calls (Inbound)

Customers can initiate a voice call to your business in three ways:

1. Call Button on Your WhatsApp Business Profile

Enable the call icon displayed directly on your WhatsApp Business number.

2. Call-In Link

Generate a call-in link and place it on your website, email, or WhatsApp messages.

Customers simply click to initiate a voice call.

3. “Call In” Button Inside WhatsApp Messages

Add a call button inside messages to encourage fast and direct call-ins.

Business-Initiated Calls (Outbound)

To use WhatsApp Calling, your business account must meet the following conditions:

1. The Business portfolio message limit must reach the 2,000 tier.

2. The phone number’s registered country must not be in the restricted regions:

   • United States

   • Canada

   • Turkey

   • Egypt

   • Vietnam

   • Nigeria

To protect user privacy, businesses must obtain user permission before initiating an outbound call.

You can obtain permission by sending:

• A template message with a calling-request button

• An interactive message prompting the customer to authorize a call

Once the user grants permission, you may place outbound calls within the authorization window.

Example: Calling Request Template
