#### Obtaining Credentials

1. Login to [West.cn Member Center](https://www.west.cn/manager/)
2. Go to "Domain Management" > Select domain > "Management Password"
3. Copy the **APIkey** (32-character MD5 value), which is the MD5 hash of the domain management password

```json
{
    "dns": "west",
    "token": "ec4c66e34561428b2e9ad65048f9bsed"  // Domain APIkey
}
```

### 2. Account Authentication

Authenticate using member account and API password.

#### Obtaining Credentials

1. Login to [West.cn Member Center](https://www.west.cn/manager/)
2. Go to "Account Management" > "API Interface Settings"
3. Set the API password
4. `id` is your member account username
5. `token` is the 32-character MD5 of your API password

```json
{
    "dns": "west",
    "id": "your_username",                      // Member account
    "token": "md5_of_your_api_password"         // MD5 of API password
}
```

## Complete Configuration Examples

}
```

    "token": "your_apidomainkey",

    "ipv4": ["ddns.example.com"]
}
```

## Troubleshooting

### Debug Mode

Enable debug logging to view detailed information:

```sh
ddns -c config.json --debug
```

### Common Issues

- **Authentication Failed**: Check if APIkey or account password is correct, confirm token is a 32-character MD5 value
- **Domain Not Found**: Ensure domain is under your West.cn account, check configuration spelling
- **Record Creation Failed**: Check if subdomain has conflicting records, verify TTL settings are reasonable
- **Request Rate Limit**: Reduce request frequency
