{
|
||||
"invoice_id": 1,
|
||||
"payment_method": "bank_transfer",
|
||||
"amount": "89.00",
|
||||
"manual_reference": "BT-2025-001",
|
||||
"manual_notes": "Transferred via ABC Bank"

## 🎯 Next Steps
|
||||
|
||||
### For Frontend Developers:
|
||||
1. Implement billing form component in signup flow
|
||||
2. Create payment method selector (fetch from API)
|
||||
3. Build payment confirmation modal/page
|
||||
4. Add pending payment banner to dashboard
|
||||
5. Test complete user journey end-to-end
|
||||
|
||||
### API Integration:
|
||||
- Use `api_integration_example.py` as reference
|
||||
- Base URL: `http://localhost:8011/api/v1/`
|
||||
- Authentication: Bearer token from login endpoint
|
||||
- See PAYMENT-WORKFLOW-QUICK-START.md for curl examples
|
||||
|
||||
### Testing:
|
||||
- Run automated tests: `docker compose exec igny8_backend python test_payment_workflow.py`
|
||||
- Manual API testing: See quick start guide
|
||||
- Database verification queries included in docs
