Meta bills your WhatsApp account directly. Here's how that works alongside Zymbler.
WhatsApp message fees are set by Meta and charged by Meta directly to your business's own WhatsApp Business account — not by Zymbler.
Meta charges per message. From 1 October 2026 that includes ordinary replies inside the 24-hour customer service window, at the utility rate for the customer's country, so the agent's replies are messages Meta bills you for once each number's 1,000 free service messages for the month are used. Marketing templates, used for a broadcast for example, cost more. When someone messages you from a Click-to-WhatsApp ad and you reply within 24 hours, your messages to them are free for a while. Plan on 72 hours: Meta's developer page says up to 7 days, and the WhatsApp Business site says 72 hours.
What changed, and the rates for each country, are in WhatsApp pricing from 1 October 2026, and the WhatsApp pricing calculator works out a monthly total.
Meta's rates vary by country and change over time, so rather than quote numbers here, see Meta's own pricing page: Meta's WhatsApp pricing.
The payment method for WhatsApp fees lives in Meta's tools, not in Zymbler. See WhatsApp message fees & payment method for where to add it.
Zymbler's plans and prices are on the pricing page. What Zymbler charges is separate from Meta's message fees.
