+# WhatsApp Business (Official API) — Usage Tips
+
+Use your COCO AI employee on the official WhatsApp Business Platform (Cloud API) — a verified business number your customers can message from their everyday WhatsApp app. Built for customer-facing business messaging at scale.
+
+> New here? See the [WhatsApp Business Deployment guide](../getting-started/channel-deployment#whatsapp-business) to connect your business number first.
+
+> **WhatsApp Business vs. WhatsApp:** This channel uses Meta's **official Cloud API** — you verify a business phone number by OTP, with no phone or QR linking. The [WhatsApp](./whatsapp) channel links a regular WhatsApp account via QR code instead. Choose this one for official, customer-facing business use.
+
+## Basic Usage
+
+### Direct Messages
+Customers send a message to your business number from their normal WhatsApp app — no special command needed. The first person to DM the number becomes the **Owner** with full access.
+
+### Group Chats
+Not supported — the official WhatsApp Business Cloud API is **1:1 (DM) only**. If you need group chat support, use the [WhatsApp](./whatsapp) channel instead.
+
+## Best Use Cases
+
+### Customer-Facing Support
+The official API is built for business-to-customer messaging:
+- Answer FAQs and product questions instantly, around the clock
+- Triage and route incoming requests
+- Serve customers on the app they already use — no install needed
+
+### Official Business Presence
+- Your business display name is shown to customers, backed by Meta's official platform
+- No linked phone to keep online — the connection is server-to-server and stays up on its own
+- Delivery and read status is tracked for outbound messages
+
+## Pro Tips
+
+**24-hour window**: WhatsApp allows freeform replies within 24 hours of the customer's last message. Outside that window, only pre-approved **template messages** can be sent — the AI employee handles this automatically.
+
+**Media in, media out**: Customers can send images, documents, audio, and video — the AI employee receives them and can reply with text, images, and documents.
+
+**Owner**: The first person to DM the business number becomes the Owner, who always has full access regardless of access settings.
+
+**Access control**: By default only the Owner can DM the number. Adjust the DM policy (owner / allowlist / open) to open it up to customers or a team.
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Bot not responding | Confirm the WhatsApp Business card shows **Connected** in the employee detail page, then send another message |
+| Replies not arriving after a long pause | The 24-hour customer-service window has likely closed — send a new message from the customer side to reopen it |
+| Can't add the bot to a group | Group chats are not supported by the official Cloud API — this channel is 1:1 only |
+| Others can't message the bot | By default only the Owner can chat. Enable Allowlist or Open mode to grant access |
+| Want to disconnect | Click the **Disconnect** button on the WhatsApp Business card in the employee detail page |

+## Option L: WhatsApp Business (Official API) Deployment {#whatsapp-business}
+
+**Estimated time: ~5 minutes**
+
+> **Note:** This channel uses Meta's **official WhatsApp Business Platform (Cloud API)**. You bring a phone number, verify it with a one-time code right in the Dashboard, and COCO handles everything on the Meta side — no Meta developer account, API keys, or QR/phone linking needed. Prefer linking a regular WhatsApp account by QR code instead? See [WhatsApp](#whatsapp).
+
+No credentials are required. You only need:
+
+| Item | Description |
+|------|-------------|
+| COCO AI Employee | An existing instance in COCO Dashboard |
+| Phone Number | A number that can receive an SMS or voice call, and is **not** currently registered on WhatsApp or another WhatsApp Business account |
+| ~5 minutes | Time to complete deployment |
+
+### Step 1: Click Connect on the WhatsApp Business Card
+
+1. Log into [COCO Dashboard](https://icoco.ai/dashboard) and open the employee instance detail page
+2. Find the **WhatsApp Business** card and click **Connect**
+
+### Step 2: Enter Your Phone Number and Display Name
+
+1. Enter the phone number you want to use, in international format (e.g. `+1 555 123 4567`)
+2. Enter a **display name** — this is the business name your customers will see in WhatsApp
+3. Check the preview carefully before continuing
+
+> **Important:** The display name is reviewed against Meta's display name policy and is **hard to change later** — choose it carefully.
+
+### Step 3: Verify with the One-Time Code
+
+1. Meta sends a **6-digit verification code** to your number via SMS (a voice call option is available if SMS doesn't arrive)
+2. Enter the code in the wizard
+
+> **Mainland China numbers:** SMS delivery to +86 numbers can be unreliable — if the code doesn't arrive, use the **voice call** option.
+
+### Step 4: Deploy
+
+1. After the code is verified, the system registers your number and deploys the channel automatically — a progress indicator shows each step
+2. When finished, the WhatsApp Business card shows **Connected**
+
+### Step 5: Start Chatting
+
+1. From any phone with WhatsApp, send a message to your business number
+2. Your AI employee responds immediately — deployment complete!
+
+> **First message:** The first user to DM the business number becomes the **Owner** (administrator), who always has full access regardless of policy settings.
+
+### WhatsApp Business FAQ
+
+| Issue | Solution |
+|-------|----------|
+| Verification code never arrives | Wait a moment and retry, or choose the **voice call** option. SMS to mainland China (+86) numbers is often unreliable |
+| "Number already in use" or verification fails | The number must not be registered on the WhatsApp consumer app or another WhatsApp Business account — remove it there first (WhatsApp → Settings → Account → Delete account), then retry |
+| Closed the wizard before finishing | Your progress is saved — click **Connect** on the WhatsApp Business card again to resume where you left off |
+| Can't use the bot in group chats | The official Cloud API is **1:1 (DM) only**. If you need group chats, use the [WhatsApp](#whatsapp) channel |
+| No reply after a long silence | WhatsApp's **24-hour customer-service window** has closed — send a new message from the customer side to reopen it; outside the window only pre-approved template messages can be sent |
+| Others can't message the bot | By default only the Owner can chat. Enable Allowlist or Open mode to grant access |
+| Want to disconnect | Click the **Disconnect** button on the WhatsApp Business card in the employee detail page |

+# WhatsApp Business（官方 API）— 使用技巧
+
+在官方 WhatsApp Business Platform（Cloud API）上使用 COCO AI 员工——一个经过验证的企业号码，客户直接用日常使用的 WhatsApp 应用就能联系你。专为规模化的企业客户消息场景打造。
+
+> 第一次使用？请先查看 [WhatsApp Business 部署指南](../getting-started/channel-deployment#whatsapp-business) 连接你的企业号码。
+
+> **WhatsApp Business 与 WhatsApp 的区别：** 本渠道使用 Meta 的**官方 Cloud API**——通过 OTP 验证码验证一个企业电话号码，无需手机扫码或设备关联。而 [WhatsApp](./whatsapp) 渠道是通过二维码关联一个普通 WhatsApp 账号。面向客户的正式商务场景请选择本渠道。
+
+## 基本使用
+
+### 私信
+客户用普通 WhatsApp 应用给你的企业号码发送消息即可——无需特殊命令。第一个给该号码发私信的用户会成为 **Owner（管理员）**，拥有完整访问权限。
+
+### 群聊
+不支持——官方 WhatsApp Business Cloud API 仅支持 **1:1 私信**。如需群聊支持，请改用 [WhatsApp](./whatsapp) 渠道。
+
+## 适用场景
+
+### 面向客户的支持
+官方 API 专为企业对客户（B2C）消息场景设计：
+- 全天候即时回答常见问题和产品咨询
+- 对收到的请求进行分流和路由
+- 在客户已经在用的应用上提供服务——无需安装任何东西
+
+### 官方商务形象
+- 客户会看到你的企业显示名称，背靠 Meta 官方平台
+- 无需保持任何手机在线——连接是服务器对服务器的，自行保持稳定
+- 出站消息的送达和已读状态会被跟踪
+
+## 进阶技巧
+
+**24 小时窗口**：WhatsApp 允许在客户最后一条消息后的 24 小时内自由回复。超出该窗口后，只能发送预先审核通过的**模板消息**——AI 员工会自动处理这一逻辑。
+
+**媒体收发**：客户可以发送图片、文档、音频和视频——AI 员工能接收它们，并可回复文字、图片和文档。
+
+**Owner（管理员）**：第一个给企业号码发私信的用户将成为 Owner，始终拥有完整访问权限，不受访问设置限制。
+
+**访问控制**：默认只有 Owner 能私信该号码。可调整私信策略（owner / allowlist / open），向客户或团队开放。
+
+## 故障排除
+
+| 问题 | 解决方案 |
+|------|---------|
+| 机器人无响应 | 确认员工详情页的 WhatsApp Business 卡片显示为**已连接**，然后再发送一条消息 |
+| 长时间未联系后收不到回复 | 24 小时客服窗口可能已关闭——由客户一侧发送一条新消息即可重新打开窗口 |
+| 无法把机器人拉进群 | 官方 Cloud API 不支持群聊——本渠道仅支持 1:1 私信 |
+| 其他人无法和机器人聊天 | 默认只有 Owner 可以聊天。启用 Allowlist 或 Open 模式以开放访问权限 |
+| 想要断开连接 | 在员工详情页的 WhatsApp Business 卡片上点击**断开连接**按钮 |

+
+**预计用时：约5分钟**
+
+> **说明：** 本渠道使用 Meta **官方 WhatsApp Business Platform（Cloud API）**。你只需提供一个电话号码，在 Dashboard 中用一次性验证码完成验证，Meta 侧的所有配置由 COCO 代为处理——无需 Meta 开发者账号、API 密钥，也无需扫码或关联手机。想通过二维码关联普通 WhatsApp 账号？请查看 [WhatsApp](#whatsapp)。
+
+无需填写凭证，只需准备：

+
+1. 登录 [COCO Dashboard](https://icoco.ai/dashboard)，进入员工实例详情页
+2. 找到 **WhatsApp Business** 卡片，点击 **连接**
+
+### 第2步：输入电话号码和显示名称
+

+3. 继续之前请仔细核对预览效果
+
+> **重要：** 显示名称需符合 Meta 的显示名称政策，且**之后很难更改**——请谨慎选择。
+
+### 第3步：输入一次性验证码
+
+1. Meta 会通过短信向你的号码发送一个 **6 位验证码**（如果短信收不到，可选择语音电话方式）
+2. 在向导中输入验证码
+
+> **中国大陆号码：** 发往 +86 号码的短信可能不稳定——如果收不到验证码，请使用**语音电话**方式。
+
+### 第4步：部署
+
+1. 验证码通过后，系统会自动注册你的号码并部署渠道——进度指示器会展示每一步
+2. 完成后，WhatsApp Business 卡片显示为**已连接**
+
+### 第5步：开始聊天
+
+1. 用任意一台装有 WhatsApp 的手机，给你的企业号码发送一条消息
+2. AI 员工会立即响应——部署完成！
+
+> **首条消息：** 第一个给企业号码发私信的用户将成为 **Owner（管理员）**，无论权限设置如何始终拥有完整访问权限。
+
+### WhatsApp Business 常见问题
+
+| 问题 | 解决方案 |
