## Overview

The **WhatsApp Cloud** channel uses **Meta's official API**. It's the recommended option for
businesses that want the official green badge, high volume, approved templates (HSM) and full
stability. The simplest way to connect is **Embedded Signup**: a guided flow from Meta itself, opened
inside the platform, where you sign in with your Facebook Business account and authorize the number in
a few steps — with no manual token copying.

At the end, the inbox is connected to your official number and ready to send and receive messages.

## Prerequisites

- An **administrator** role in the platform.
- A **Facebook Business / Meta Business Manager** account.
- A phone number **not in use on another WhatsApp account** (or ready to migrate to the Cloud API).
- Access to complete the **number verification** (by SMS or call).
- In some environments, Embedded Signup must be enabled by the operator — if it doesn't appear, talk
  to whoever runs the operation.

## Step by step

1. In **Settings → Inboxes**, create a new inbox and choose **WhatsApp**.
2. Select the **WhatsApp Cloud** provider and the **Embedded Signup** option.
3. Click **Connect with Meta**. A Meta window opens over the platform.
4. Sign in with your Facebook account and select (or create) the **WhatsApp Business account**.
5. Choose or register the **phone number** to be used.
6. Complete the **number verification** with the code received by SMS or call.
7. Authorize the requested permissions and finish. The platform creates the inbox automatically.
8. Assign agents/teams and send a test message.

## Settings & options

- **Number and profile**: the display name and business profile picture are managed in Meta; the
  approval status appears in Business Manager.
- **Templates (HSM)**: business-initiated messages outside the 24h window require approved templates —
  see the WhatsApp Inbox Suite.
- **Webhooks**: the Embedded Signup connection automatically sets up message receiving; you don't need
  to paste URLs manually.
- **Migration**: you can migrate a number currently on the official app to the Cloud API.

## Use cases

- Run an official number with the green badge and high support volume.
- Send approved templates (HSM) for notifications, confirmations and campaigns.
- Professionalize the operation by moving from WhatsApp Web to the official API.

## Tips, limits & best practices

- The **messaging limit** starts in a tier and grows with quality and volume — track it in Business
  Manager.
- Keep the **number quality** high: avoid blocks and reports to avoid dropping a tier.
- Outside the **24-hour window** after the customer's last message, you can only start a conversation
  with an **approved template**.

## Troubleshooting

- **The Meta window won't open**: check that the browser pop-up blocker is disabled.
- **Number already in use**: the number must be released from the old account or migrated to the Cloud
  API.
- **Verification failed**: confirm the number and try the alternative method (SMS or call).
- **Can't start a conversation**: check whether you're inside the 24h window or use an approved
  template.
