# Overview

> What a WhatsApp app is in ApifyCloud and how it fits into your product

A **WhatsApp app** in ApifyCloud is everything you need to operate one
WhatsApp Business number: template library, contact lists, campaigns,
conversation inbox, flow builder, voice calling, analytics, and audit
logs — all in one place.

## What one app represents

One app maps to **one WhatsApp Business number**:

* Each number is a separate ApifyCloud app
* Each app has its own contacts, campaigns, flows, members,
  permissions, quality score, and spend tracker

**Templates are the exception.** They're scoped to your WhatsApp
Business Account (WABA) at Meta, not to the individual number. Two
apps registered under the same WABA share the same template library —
a template approved for one number is usable from the other.

<Note>
  If you need a second number — for a different brand, region, or use
  case — create a second app. Contact lists, campaigns, and flows stay
  in their own app; templates follow the WABA.
