Choosing between the WhatsApp Business App and the WhatsApp Business API is the first decision for any business in Singapore looking to use WhatsApp professionally. Here's a clear comparison.
The Free App: Good for Solo Operators
The WhatsApp Business App is free, supports one device (plus linked devices), handles basic business profiles, quick replies, and broadcast lists of up to 256 contacts who have your number saved. Perfect if you handle under 20 conversations per day.
The API: Built for Growing Businesses
The WhatsApp Business API (via platforms like App-ening) supports multiple agents, unlimited contacts, bulk campaigns, automation workflows, CRM integration, payment collection, AI chatbot, analytics, and official business verification.

When to Switch to the API

How to Migrate Without Losing Your Number
App-ening migrates your existing WhatsApp Business number to the API. Your number stays the same. Your business profile transfers. Existing contacts can still message you. The switch takes about 10 minutes.
