KB Star Banking API Integration and Open Finance

Standard Deliverables Package

• API design documents (OpenAPI / Swagger)
• Protocol and authorization flow analysis report (including SmartOTP / fingerprint / KB National Authentication)
• Runnable source code (Node.js / Python) and deployment instructions
• Automated test scripts, sample requests and Postman collection
• Compliance and privacy recommendations (data minimization, logging and traceability)

Interface Example (Pseudo-code)

// Login: exchange a one-time auth code for an access token (pseudo)
POST /api/v1/kb/auth/exchange
Content-Type: application/json
{
  'device_id':'DEVICE123',
  'auth_code':'ONE_TIME_CODE_FROM_APP'
}

Response:
{
  'access_token':'ey..',
  'refresh_token':'rt..',
  'expires_in':3600
}

// Query account balance

Authorization: Bearer <access_token>

// Pull transactions (paginated)
POST /api/v1/kb/accounts/transactions/query
Authorization: Bearer <access_token>
{
  'account_id':'123-456-789',
  'from':'2025-10-01',

  'page':1,
  'page_size':100
}

Delivery Timeline & Example Flow

Typical small-scale integration (login + accounts + transaction queries): 5–12 business days. More complex scenarios (multi-factor authentication, enterprise accounts, third-party approvals) may take longer.

1. Requirements confirmation (provide App name and specific needs).
2. Protocol analysis and feasibility assessment (2–5 business days).
3. Development and internal validation (3–8 business days).
4. Delivery of documentation, samples and test cases (1–2 business days).

Core Advantages

• Experience with overseas and local bank integrations; familiar with mainstream mobile banking authentication methods
• Deliver compliant, secure APIs with data minimization strategies
• Supports Android / iOS cross-platform protocol analysis and SDK packaging
• Transparent pricing with pay-on-delivery model

API Integration Tips (Quick Guide)

1. Please provide the target App identifier (this time: KB Star Banking) and required features (e.g., card management, transaction export, auto-login).
2. If developer credentials or a test environment exist, please provide them; if not, we can perform protocol reverse engineering to form a runnable solution and confirm authorization boundaries.
3. The initial release will include authentication examples, account/transaction APIs, error codes, and a Postman test collection.
4. Recommend security audits and compliance checks (KYC, data access logging) before production integration.
