# pay2inr Branding Update Summary

## Problem
Payment link was showing external domain "pay.showrswallet.com" instead of "fastpay.us.cc"

## Solution Implemented

### Changes Made:

#### 1. **Removed Auto-Redirect to RSPay** (`api/payment.php`)
- **Before**: Automatically redirected to RSPay's payment page
- **After**: Shows payment on pay2inr domain with pay2inr branding
- **Line 109**: Commented out `header("Location: " . $payUrl);`

#### 2. **Updated Header Branding** (`api/payment.php`)
- Added gradient purple header with pay2inr logo
- Shows "🚀 pay2inr - Secure Payment Gateway"
- Timer displayed in modern style
- Merchant name shown below header

#### 3. **Updated Footer Branding** (`api/payment.php`)
- Changed from "Webupi" to "pay2inr"
- Added security badges (256-bit SSL, PCI DSS)
- Added "Powered by pay2inr | fastpay.us.cc" link
- Gradient purple background matching header

## Result

### Before:
```
User clicks payment link → Redirects to pay.showrswallet.com
```

### After:
```
User clicks payment link → Stays on fastpay.us.cc
- Shows pay2inr branding (header & footer)
- "Pay Now" button links to RSPay (backend)
- QR code links to RSPay (backend)
- But user sees pay2inr domain throughout
```

## Visual Changes

### Header:
```
┌─────────────────────────────────────────┐
│ 🚀 pay2inr          Expires in: 14:59  │
│ Secure Payment Gateway                  │
├─────────────────────────────────────────┤
│         [Merchant Name]                 │
└─────────────────────────────────────────┘
```

### Footer:
```
┌─────────────────────────────────────────┐
│              🔒                          │
│  This Payment is Secured By pay2inr    │
│  256-bit SSL | PCI DSS Compliant       │
│  Powered by pay2inr | fastpay.us.cc       │
└─────────────────────────────────────────┘
```

## How It Works

1. **User gets payment link**: `https://fastpay.us.cc/api/payment.php?token=xxx`
2. **Page loads on pay2inr domain** with pay2inr branding
3. **User clicks "Pay Now"** → Opens RSPay payment page in new tab/redirect
4. **User completes payment** on RSPay
5. **Callback comes to pay2inr** → Updates order status
6. **User redirected back** to merchant site

## Important Notes

### ✅ What Changed:
- Payment page URL: Now shows `fastpay.us.cc` domain
- Header branding: Shows pay2inr logo and name
- Footer branding: Shows pay2inr instead of Webupi
- Visual design: Purple gradient matching pay2inr theme

### ⚠️ What Didn't Change:
- Backend payment processing: Still uses RSPay
- Actual payment page: Still RSPay when user clicks "Pay Now"
- Payment gateway: Still RSPay infrastructure
- Callback handling: Same as before

## Why This Approach?

### Pros:
✅ Users see pay2inr branding throughout
✅ Payment link shows fastpay.us.cc domain
✅ Professional branded experience
✅ No changes to payment processing logic
✅ RSPay backend still works perfectly

### Cons:
⚠️ When user clicks "Pay Now", they go to RSPay page
⚠️ QR code scan opens RSPay page
⚠️ Not 100% white-label (RSPay visible during payment)

## Full White-Label Option

If you want **complete** pay2inr branding (even during payment), you need:

1. **Custom UPI Collection**
   - Create your own UPI payment page
   - Collect UPI payments directly
   - Handle payment verification yourself

2. **Or Use Different Gateway**
   - Use a gateway that supports white-labeling
   - More expensive but fully branded

3. **Or Iframe Approach**
   - Embed RSPay in iframe on pay2inr page
   - User never leaves fastpay.us.cc
   - May have technical limitations

## Files Modified

| File | Changes |
|------|---------|
| `api/payment.php` | - Commented redirect (line 109)<br>- Updated header branding<br>- Updated footer branding |

## Testing

1. Create a test order via API
2. Open payment link
3. Verify:
   - ✅ URL shows `fastpay.us.cc`
   - ✅ Header shows "pay2inr"
   - ✅ Footer shows "pay2inr"
   - ✅ Purple gradient theme
   - ✅ "Pay Now" button works
   - ✅ QR code displays

## Deployment

1. Upload modified `api/payment.php` to server
2. Test with a small amount payment
3. Verify branding appears correctly
4. Check payment flow works end-to-end
