Official WhatsApp API for Business Messaging: Get Started the Right Way

Official WhatsApp API for Business Messaging - Instant Broadcast appointment confirmation template

The official WhatsApp API for business messaging is Meta's WhatsApp Business Platform, also called the WhatsApp Cloud API. It lets a business message customers at scale under its own business name, using approved templates, chatbots and integrations. Instant Broadcast connects your number to this official API and gives you a ready-to-use portal and a REST API, so you can start without building anything yourself.

What Makes It the Official WhatsApp API for Business Messaging

Only Meta's WhatsApp Business Platform is officially allowed for business messaging at scale. Tools that automate WhatsApp Web or the phone app are unofficial. They go against WhatsApp's terms and often get numbers banned. The official API is hosted by Meta in the cloud. Businesses reach it through a provider's software or by building on it directly with their own developers.

What you can do with the official WhatsApp API

  • Send template messages to opted-in customers, such as offers, order updates, reminders and OTPs.
  • Reply freely inside the 24-hour customer service window after a customer messages you.
  • Use interactive messages with quick-reply and call-to-action buttons, lists, images, video and documents.
  • Run chatbots that answer and route conversations automatically.
  • Let many agents reply from one business number through a team inbox.
  • Connect your systems so events in your store, CRM or app send WhatsApp messages.

Three ways to use the official API

Key rules of the official API

  1. Opt-in is required. Message customers only after they've agreed to hear from you.
  2. Templates for business-initiated messages. Meta reviews and approves message templates before you use them.
  3. The 24-hour window. After a customer messages you, you can reply freely for 24 hours. After that, you need a template.
  4. Quality and limits. Your number has a quality rating and a daily messaging limit that grows with good quality and business verification.
  5. Per-message pricing. Template messages are charged by category: marketing, utility or authentication.
