Summary
The WhatsApp Business API is designed for businesses that need to communicate with customers at scale. It enables automation, shared team access, integrations with business systems, and advanced messaging capabilities that are not available in the WhatsApp Business App. This guide explains what the WhatsApp Business API is, how it differs from the WhatsApp Business App, what Wati provides, and the key requirements and limitations to understand before getting started.
Overview
What is WhatsApp Business API?
The WhatsApp Business API is built for growing businesses that need to manage customer conversations at scale. Unlike the WhatsApp Business App, it allows businesses to automate communication, connect WhatsApp with other business systems, and manage conversations across multiple team members.
With the WhatsApp Business API, businesses can:
Automate customer conversations
Build WhatsApp chatbots
Send interactive messages
Integrate WhatsApp with external systems and applications
Manage customer conversations across multiple agents
Scale customer communication as the business grows
WhatsApp Business App vs. WhatsApp Business API
The WhatsApp Business App is a free application designed primarily for small businesses that manage customer conversations manually. While it provides the basic tools needed to communicate with customers, it has limitations as your business grows.
Compared to the WhatsApp Business App, the WhatsApp Business API provides:
Feature | WhatsApp Business App | WhatsApp Business API |
Agents | 1 | Unlimited |
Broadcast messaging | Limited | Starts at 250, scales up to unlimited based on usage and message quality |
Automation | ✗ | ✓ |
Analytics | ✗ | ✓ |
Integrations | ✗ | ✓ |
Artificial Intelligence (AI) | ✗ | ✓ |
Messaging limits apply at the business portfolio level and are shared across all connected phone numbers. Limits increase automatically as your business sends high-quality messages at volume.
The WhatsApp Business API is the better choice for businesses that need to support multiple team members, automate customer interactions, and communicate with customers at scale.
What is Wati?
Wati is a customer engagement platform built on the WhatsApp Business API as its core. While it supports multiple messaging channels including Instagram, Facebook, SMS, and TikTok, WhatsApp is the primary channel and the WhatsApp Business API powers its messaging capabilities.
With Wati, businesses can:
Send and receive WhatsApp messages
Manage customer conversations from a shared inbox
Automate responses and workflows
Build WhatsApp chatbots
Connect WhatsApp with other business tools and systems
Manage customer support, sales, and marketing conversations from a single platform
Things to know before getting started
Before connecting your phone number to the WhatsApp Business API, keep the following in mind:
Previous WhatsApp chat history is not available after onboarding through a WhatsApp Business API solution provider such as Wati.
Wati offers two ways to connect your phone number, each with different rules:
Embedded Signup — your phone number cannot be used with the WhatsApp Messenger app or the WhatsApp Business App while connected to Wati.
Coexistence onboarding — your phone number can be used with both Wati and the WhatsApp Business App simultaneously.
Understanding WhatsApp Business API messaging rules
WhatsApp applies messaging rules to help protect the customer experience.
1. Customer-initiated conversations
When a customer sends a message to your business, a 24-hour customer service window opens during which your business can respond freely using any message type, without needing an approved template.
2. Business-initiated conversations
Once the 24-hour customer service window ends, businesses must use an approved WhatsApp template message to start a new conversation.
Template messages:
Must be approved by WhatsApp before they can be used
Can be managed from the Wati dashboard
Must comply with WhatsApp Commerce Policies
