What Is the WhatsApp Business API? Differences from Regular WhatsApp and Meaning for SMEs

Share: WhatsApp𝕏 Share

WhatsApp has three distinct faces, and the similarity in names causes confusion: regular WhatsApp on your phone, the WhatsApp Business app for local merchants, and the WhatsApp Business API behind the scenes (now also called the WhatsApp Business Platform). Chatbots, automation, and multi-user support are only possible on the third one.

Comparison of the Three

What Does 'No App' Mean for the API?

The Business API is not a phone application; your number is connected to Meta's infrastructure and messages land on the dashboard of the software you use. In a BozLat AI installation, this means: your customers write to you from their usual WhatsApp, the AI handles the messages, and you monitor all conversations from the BozLat dashboard. Your number remains yours.

Decision Rule for SMEs

For sole proprietors receiving 5-10 messages a day and wishing to handle them all themselves, the Business app is sufficient. For businesses with growing message volumes, missed out-of-office opportunities, or appointment/order traffic, the API + AI layer is the correct step—cost starts at ₺1,499 per month per channel. We discussed the setup steps in this guide and the data/privacy dimension in our KVKK article.

Important warning: unofficial tools promising a 'WhatsApp bot' by connecting to your phone via QR code can lead to your number being banned. Your business number is part of your brand; do not take it outside the official infrastructure.

Frequently Asked Questions

If I migrate my current number to the API, will my WhatsApp history be deleted?
Once the number is migrated to the API, usage on the phone app ends; old conversation history is not carried over to the new dashboard. Therefore, it is necessary to back up before the transition and plan the transition timing—we guide you during setup.
Do I pay Meta separately for the API?
Meta applies conversation-based pricing; the message quota in BozLat AI packages is designed to cover typical SME traffic. Details are finalized during the proposal stage.
Can I get a green confirmation badge?
The badge is subject to Meta's approval and is granted to well-known brands; applications can be made through the API but are not guaranteed.
I have multiple branches, should it be a single number?
Both setups are possible: a single central number + a bot asking for branch information, or a number per branch. For multiple branches, we recommend a custom setup with the Enterprise package.
