PaymentMethodSelect.tsx **Location:** `/data/app/igny8/frontend/src/components/billing/PaymentMethodSelect.tsx` **Purpose:** Displays available payment methods based on country **Features:** - Fetches from `GET /api/v1/billing/admin/payment-methods/?country={code}` - Radio button selection - Shows instructions for manual methods (bank transfer, wallets) - Loading and error states - Country-specific filtering **Props:** ```typescript interface PaymentMethodSelectProps { countryCode: string; selectedMethod: string | null; onSelectMethod: (method: PaymentMethodConfig) => void; error?: string; } ``` **API Response:** ```json { "success": true, "results": [ { "id": 14, "payment_method": "bank_transfer", "display_name": "Bank Transfer", "instructions": "Transfer to Account: 1234567890...", "country_code": "PK", "is_enabled": true, "sort_order": 10 } ] } ``` --- ### 3.

Get Payment Methods ``` GET /api/v1/billing/admin/payment-methods/?country={code} ``` **Response:** ```json { "success": true, "results": [ { "id": 14, "payment_method": "bank_transfer", "display_name": "Bank Transfer - Pakistan", "instructions": "Bank: HBL\nAccount: 1234567890\nIBAN: PK...", "country_code": "PK", "is_enabled": true, "sort_order": 10 } ], "count": 1 } ``` #### 2. Confirm Payment ``` POST /api/v1/billing/admin/payments/confirm/ Content-Type: application/json Authorization: Bearer {token} { "invoice_id": 123, "payment_method": "bank_transfer", "amount": "89.00", "manual_reference": "TXN123456789", "manual_notes": "Paid via JazzCash", "proof_url": "https://s3.amazonaws.com/..." } ``` **Response:** ```json { "success": true, "message": "Payment confirmation submitted for admin approval", "payment": { "id": 456, "status": "pending_approval", "invoice_id": 123, "amount": "89.00", "manual_reference": "TXN123456789" } } ``` #### 3. Get Pending Invoices ``` GET /api/v1/billing/invoices/?status=pending&limit=1 Authorization: Bearer {token} ``` --- ## User Flows ### Flow 1: Free Trial Signup 1. User visits `/signup` (no `?plan=` parameter) 2. SignUpFormEnhanced shows **Step 1 only** (basic info) 3. User fills name, email, password, agrees to terms 4. Clicks "Start Free Trial" 5. Backend creates account with: - `status='trial'` - `credits=1000` - No subscription or invoice 6. User redirected to `/sites` ✅ ### Flow 2: Paid Plan Signup (e.g., Starter) 1. User visits `/signup?plan=starter` 2. SignUpFormEnhanced loads plan details 3. **Step 1:** User enters basic info → "Continue to Billing" 4. **Step 2:** User enters billing info → "Continue to Payment" 5. **Step 3:** User selects payment method (e.g., bank_transfer) → "Complete Registration" 6. Backend creates: - Account with `status='pending_payment'` - Subscription with `status='pending_payment'` - Invoice with `status='pending'` for $89 - No credits allocated yet 7. User redirected to `/account/plans` 8. **PendingPaymentBanner** appears with invoice details 9. User clicks "Confirm Payment" → opens PaymentConfirmationModal 10. User enters transaction reference, uploads receipt → "Submit Payment Confirmation" 11. Backend creates Payment with `status='pending_approval'` 12. Admin approves payment (via Django admin or future admin panel) 13. Backend atomically: - Updates Payment to `status='succeeded'` - Updates Invoice to `status='paid'` - Updates Subscription to `status='active'` - Updates Account to `status='active'` - Allocates 1000 credits 14. User refreshes → PendingPaymentBanner disappears ✅ --- ## Styling & UX ### Design System - **Framework:** TailAdmin template (React + Tailwind CSS) - **Components:** Consistent with existing form elements - **Icons:** Lucide React + custom SVG icons - **Colors:** - Brand: `brand-500` (primary actions) - Success: `green-500` - Warning: `amber-500` - Error: `red-500` - Info: `blue-500` ### Responsive Design - Mobile-first approach - Grid layouts: `grid grid-cols-1 sm:grid-cols-2` - Breakpoints: `sm:`, `md:`, `lg:`, `xl:` - Touch-friendly buttons (min 44x44px) ### Accessibility - Form labels with `
