WhatsApp API — Frequently Asked Questions
What is the WhatsApp Business API?
The WhatsApp Business API is Meta's official programmatic interface that allows businesses to send messages, notifications, and engage with customers at scale. Unlike the WhatsApp Business App, the API is designed for businesses that need to integrate messaging into CRMs, dashboards, and custom backend systems. StartMessaging is an official BSP providing direct access.
How much does WhatsApp Business API cost?
WhatsApp API pricing is conversation-based, set by Meta and varying by country and message category (marketing, utility, authentication, service). StartMessaging adds no markup to Meta's base pricing. We offer plans tailored for businesses of all sizes, along with volume discounts for high-usage clients.
Can I send promotional messages on WhatsApp?
Yes! WhatsApp allows marketing messages to opted-in contacts. You can send promotions, product launches, event invitations, and personalized offers using pre-approved templates.
