Calling API Pricing

Updated: Mar 30, 2026
All user-initiated calls are free.

Overview

Businesses are charged for calls based on:
    Duration of the call (calculated in six-second pulses)Country code of the phone number being calledVolume tier (based on minutes called within the calendar month) using same tiering accrual as messaging
    Note: Our systems count fractional pulses as one pulse. For example, a 56-second call (9.33 pulses) would be counted as 10 pulses.
    For calls that cross pricing tiers (for example from the 0 - 50,000 tier to the 50,001 - 250,000 tier), the entire call is priced at the lower rate (that is, the rate of the higher volume tier).
    A valid payment method is required to place calls.
    Note: Call permission request messages are subject to per-messaging pricing.

      How calling changes the 24 hour customer service window

      Currently, when a WhatsApp user messages you, a 24-hour timer called a customer service window begins, or refreshes.
      When you are within the window, your business can send any type of message to the WhatsApp user, which is otherwise not allowed.
      With the introduction of the Calling API, the customer service window now also starts or refreshes for calls:
