SBI Card Mobile App API Integration · OpenFinance / Protocol Analysis

Delivery Items (Sample)

• Detailed protocol analysis report (authentication flows, token lifecycle, session management)
• REST API implementation with OpenAPI (Swagger) documentation
• Runnable backend examples (Node.js / Python), including authentication, retries, and rate limits
• Automation tests and sample data (Postman / pytest)
• Compliance recommendations (data minimization, logging, and user consent records)

  "from_date": "2025-09-01",
  "to_date": "2025-09-30",
  "format": "excel|json"
}

Response 200 {
  "status": "OK",
  "period": "2025-09",
  "balance_due": 12500.00,
  "transactions": [ /* list */ ],
  "download_url": "https://.../statements/2025-09.xlsx"
}

Key Integration Scenarios

Billing sync to enterprise financial systems, automated repayments (across multiple payment channels), bulk report exports, card lifecycle management, and reconciliation automation. Access requires explicit user authorization.

API Integration Instructions (for Clients)

1. Provide target App name and package name (e.g., SBI Card Mobile App, package=com.ge.capital.konysbiapp).
2. List required capabilities: statement export, repayment initiation, EMI processing, QR payments, card controls, etc.
3. Provide test accounts or authorization flow details (if real user data is needed, user consent or a simulated environment is required).
4. Clarify compliance/regional requirements (e.g., RBI/NPCI in India), and whether an NDA is needed.
5. Deliverables: protocol analysis → prototype API → validation tests → complete documentation and source code (deployment support optional).

Note: We operate strictly based on client authorization or public/licensed APIs; if reverse engineering of non-public protocols is required, we will confirm legal and compliance boundaries with the client and sign necessary agreements.

Sample: Initiate Credit Card Repayment (Curl Mock)

# Initiate repayment (mock)

  -d '{
    "card_id":"XXXX-XXXX-XXXX-1234",
    "amount": 12500.00,
    "payment_method":"netbanking|debit_card|upi",
    "notify_url":"https://your.app/webhook/payment-callback"
  }'
