Business App vs Cloud API — what you need before you start
EezieLead runs on the WhatsApp Cloud API, not the WhatsApp Business App. Here's the difference and why it matters.
EezieLead runs on the WhatsApp Cloud API, not the WhatsApp Business App. These are two different products from Meta, and this one difference decides everything about your setup — so it's worth one minute now.
The two products
The green WhatsApp Business App is the app you install on a phone and tap to reply by hand. The WhatsApp Cloud API is Meta's platform that lets software — like EezieLead — send and receive messages on your number automatically.
| Business App | Cloud API (EezieLead) | |
|---|---|---|
| Where it runs | An app on one phone | Meta's cloud, connected to EezieLead |
| Can software auto-reply? | No — the app has no API, ever | Yes — that's the whole point |
| Who answers | You, by hand | AI first, you take over anytime |
| Manual broadcast/blast | Free, manual | Reaching people outside the 24h window needs an approved template |
What each one costs is a separate question, and the answer changes on 1 October 2026. See message costs.
Why it matters for you
Already using this number on the green Business App? You don't have to give it up. With Meta's Coexistence, you connect your existing number to the Cloud API and keep using the Business App at the same time — both run together, and your chats stay put. We walk you through it in Already using this number on the Business App?.
If your number is brand new (not yet on any WhatsApp Business product), you can go straight to connecting your number.
