## 📋 Next Steps - Provide Your Templates

You mentioned you'll provide the templates and specify where/when to send SMS. Here's what I need from you:

### 1. SMS Templates

For each template, provide:
- **Name**: e.g., "Booking Confirmation"
- **When to send**: e.g., "When booking is created"
- **Message content**: With placeholders like `{customer_name}`, `{booking_date}`, etc.
- **Variables available**: What data should be included

**Example:**
```
Template: Booking Confirmation
When: After booking is created
Message: "Hi {customer_name}, your appointment for {service_name} on {booking_date} at {booking_time} is confirmed. See you at {company_name}!"
Variables: customer_name, service_name, booking_date, booking_time, company_name
```

### 2. Trigger Events

Tell me when SMS should be sent:
- ✅ Booking created
- ✅ Booking cancelled
- ✅ Booking reminder (when? 1 day before? 1 hour before?)
- ✅ Employee created
- ✅ OTP verification
- ✅ Password reset
- ✅ Any other events?

### 3. Email vs SMS

For each event, specify:
- Send SMS only?
- Send Email only?
- Send both SMS and Email?

## 🎯 How to Configure Twilio

### Step 1: Get Twilio Credentials

1. Sign up at https://www.twilio.com/
2. Go to Console → Settings → General Settings
3. Copy:
   - **Account SID** (starts with AC...)
   - **Auth Token**
4. Buy a phone number from Phone Numbers → Buy a Number
5. Copy the **Phone Number** (starts with +...)

### Step 2: Configure in Admin Panel

Go to: `https://yourdomain.com/admin/sms-settings`

**POST request to configure:**
```json
{
  "provider": "twilio",
  "twilio_sid": "ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "twilio_token": "your_auth_token_here",
  "twilio_phone_number": "+1234567890",
  "status": true,
  "use_whatsapp": false
}
```

### Step 3: Test Configuration

Send a test SMS:
```bash
POST /admin/sms-settings/test
{
  "to": "+1234567890"
}
```

## 💡 Usage Examples

### Send Booking Confirmation

```php
use App\Helpers\NotificationHelper;

$notificationHelper = new NotificationHelper();
$notificationHelper->sendBookingConfirmation($booking);
```

### Send Custom SMS

```php
$notificationHelper->sendCustomSms(
    '+1234567890',
    'Your custom message here',
    $userId
);
```

### Check if SMS Enabled

```php
if ($notificationHelper->isSmsEnabled()) {
    // Send SMS
}
```
