(LandinChat – WhatsApp Business API)
The WhatsApp Business API is a paid API.
Meta (WhatsApp) charges a per-conversation fee for messages sent and received through the API.
To avoid message failures or account restrictions, you must add a payment method in your Meta Business Manager.
This guide explains how to do that correctly.
Why Adding a Payment Method Is Mandatory #
- WhatsApp API conversations are billed by Meta
- Billing does not go through WatsAppKaro
- Without a payment method:
- Messages may fail
- Your WhatsApp account can be paused or restricted
Adding billing ensures uninterrupted WhatsApp API access.
