# Add WhatsApp Cloud API Channel
Connect NanoClaw to WhatsApp via the official Meta WhatsApp Business Cloud API.
## Install
NanoClaw doesn't ship channels in trunk. This skill copies the WhatsApp Cloud adapter in from the `channels` branch.
### Pre-flight (idempotent)
Skip to **Credentials** if all of these are already in place:
- `src/channels/whatsapp-cloud.ts` exists
- `src/channels/index.ts` contains `import './whatsapp-cloud.js';`
- `@chat-adapter/whatsapp` is listed in `package.json` dependencies
Otherwise continue. Every step below is safe to re-run.
### 1. Fetch the channels branch
```bash
git fetch origin channels
```
### 2. Copy the adapter
```bash
git show origin/channels:src/channels/whatsapp-cloud.ts > src/channels/whatsapp-cloud.ts
```
### 3. Append the self-registration import
Append to `src/channels/index.ts` (skip if the line is already present):
```typescript
import './whatsapp-cloud.js';
```
### 4. Install the adapter package (pinned)
```bash
pnpm install @chat-adapter/[email protected]
```
### 5. Build
```bash
pnpm run build
```
## Credentials
1. Go to [Meta for Developers](https://developers.facebook.com/apps/) and create an app (type: Business).
2. Add the **WhatsApp** product.
3. Go to **WhatsApp** > **API Setup**:
- Note the **Phone Number ID** (not the phone number itself).
- Generate a **permanent System User access token** with `whatsapp_business_messaging` permission.
4. Go to **WhatsApp** > **Configuration**:
- Set webhook URL: `https://your-domain/webhook/whatsapp`.
- Set a **Verify Token** (any random string you choose).
- Subscribe to webhook fields: `messages`.
5. Copy the **App Secret** from **Settings** > **Basic**.
### Configure environment
Add to `.env`:
```bash
WHATSAPP_ACCESS_TOKEN=your-system-user-access-token
WHATSAPP_PHONE_NUMBER_ID=your-phone-number-id
WHATSAPP_APP_SECRET=your-app-secret
WHATSAPP_VERIFY_TOKEN=your-verify-token
```
Sync to container: `mkdir -p data/env && cp .env data/env/env`
## Next Steps
If you're in the middle of `/setup`, return to the setup flow now.
Otherwise, run `/manage-channels` to wire this channel to an agent group.
## Channel Info
- **type**: `whatsapp-cloud`
- **terminology**: WhatsApp Cloud API supports 1:1 conversations only (no group chats). Each conversation is with a phone number.
- **how-to-find-id**: The platform ID is the Phone Number ID from the Meta Business dashboard (not the phone number itself). Find it under WhatsApp > API Setup.
- **supports-threads**: no
- **typical-use**: Interactive 1:1 chat -- direct messages only
- **default-isolation**: Same agent group if you're the only person messaging the bot. Each additional person who messages gets their own conversation automatically, but they share the agent's workspace and memory -- use a separate agent group if you need information isolation between different contacts.
