Official WhatsApp API vs WhatsApp Business app: which fits your Singapore business?
Singapore businesses usually start on the free WhatsApp Business app. As enquiries grow, many hit its limits and look at the Official WhatsApp Business API. Here is how to decide.
WhatsApp Business app
- Free, installed on a phone, and quick to set up.
- Good for small teams with modest message volume.
- Limited team access, limited automation, and sending bulk messages from it risks restrictions on your number.
Official WhatsApp Business API
- Built for volume, with several team members working in one shared inbox.
- Verified business messaging and message templates approved by WhatsApp.
- Works with AI chatbots and automation platforms such as Dreamztrack.
- Charged per conversation or message by WhatsApp, in addition to your platform fee. Rates change, so check the current official rate card.
Which one should you choose?
| If you… | Choose |
|---|---|
| Get a few dozen enquiries a day and one person replies | WhatsApp Business app |
| Run ads that drive hundreds of enquiries a week | Official API |
| Need several staff replying from one number | Official API |
| Plan to blast promotions to opted-in customers | Official API with approved templates |
| Want a verified business profile | Official API |
You do not have to choose forever
Many businesses start with a normal WhatsApp channel connected to an AI salesman, then add an Official channel as volume and compliance needs grow. Dreamztrack supports both channel types, and each channel includes one AI salesman.
A quick checklist before you switch
- Which number will you use? Moving a number to the API changes how the Business app works on it.
- Who needs access to the inbox?
- What templates do you need approved (order updates, appointment reminders)?
- Have you set a budget for per-message charges?
