Getting Started with WhatsApp Business API in 2026
A complete guide to setting up WhatsApp Business API for your business, from registration to sending your first message.
WhatsApp Business API has become an essential tool for businesses looking to connect with customers at scale. Unlike the regular WhatsApp Business app, the API allows you to integrate WhatsApp messaging directly into your business systems.
Why Choose WhatsApp Business API?
The API offers several advantages over the regular WhatsApp Business app: unlimited agents can use the same number, you can automate messages with workflows, send broadcast campaigns to thousands of contacts, and integrate with your CRM and other tools.
Requirements for Getting Started
Before you can use the WhatsApp Business API, you'll need: a verified Facebook Business Manager account, a dedicated phone number not already registered on WhatsApp, and a Business Solution Provider (BSP) like UnifyBox to access the API.
