Two ways to connect WhatsApp to your system
When you decide to automate support, the first question appears: how do you connect WhatsApp to the platform? In Zapini there are two paths — connecting via QR Code and the official WhatsApp Cloud API. Each has advantages and limitations, and the right choice depends on the size and goals of your business.
In this guide, we explain how each method works, their differences, and how to decide which one to use.
How the QR Code connection works
The QR Code connection works much like WhatsApp Web: you open the app on your phone, scan a code, and your number is connected to the platform. It's fast, simple, and works with any number, including a regular WhatsApp account.
- Instant activation: just scan the code.
- No prior approval of numbers or messages.
- Lower entry cost, ideal for getting started.
- Depends on the device and keeping the session active.
It's the perfect option for beginners, small businesses, and anyone who wants to test automation quickly.
How the WhatsApp Cloud API works
The Cloud API is WhatsApp's official solution for businesses. Instead of scanning a phone, the number is registered directly on Meta's infrastructure. This brings more stability and features designed for larger operations.
- Official, stable connection, with no reliance on a device.
- Higher message volume with predictability.
- Advanced features such as approved message templates.
- A more involved setup process with Meta's rules.
It's the ideal choice for growing companies, high-volume operations, and anyone seeking the official account badge.

Which one to choose for your business
There's no single answer — there's the right option for your current stage. Use this summary as guidance:
- Just starting or want to test? QR Code is the fastest and cheapest path.
- Have growing volume and need stability? The Cloud API delivers predictability and official features.
- Want flexibility? With Zapini you can start on QR Code and migrate to the Cloud API when it makes sense.
The best method is the one that fits your business's current stage — and lets you evolve without rebuilding everything.
