Shinhan Super SOL — OpenFinance Integration

Deliverables

• OpenAPI / Swagger specification and sequence diagrams
• Protocol & auth analysis report (OAuth2, mTLS, device binding)
• Runnable server code (Node.js / Python) with tests
• Client SDK snippets and sample frontend integration
• Compliance checklist (KYC, logging, consent capture)

Example API: Account & Transaction Search (pseudo)

{
  "POST /api/v1/shinhan/sessions": {
    "description": "Exchange login assertion for access token",
    "body": {"username":"user","password":"••••"}
  }
}

GET /api/v1/shinhan/accounts
Authorization: Bearer <ACCESS_TOKEN>

GET /api/v1/shinhan/accounts/{accountId}/transactions?from=2025-01-01&to=2025-09-30&query=coffee

Response: {
  "accountId": "123-456",
  "balance": 10234.50,
  "transactions": [ /* paginated list */ ]
}

Typical integration scenarios

Account aggregation, transfer orchestration, card lock/unlock from third-party portals, cross-product journeys (one-click loan or investment application) and multi-tenant enterprise onboarding.

Core benefits

• Ready-to-run code that minimizes time-to-market
• Privacy-first design & consent capture workflows
• Cross-platform support (Android / iOS sample clients)
• Clear audit trails and logging for compliance
• Modular APIs for easy extension and scaling

How we approach integration

1. Requirements intake — target app features you need (account, payments, cards).
2. Protocol analysis — map auth flows, token lifecycle, device binding.
3. Design & implementation — deliver API spec, code and SDKs.
4. Verification & test plan — automated tests and sample scenarios.
5. Handover & compliance guidance — docs, OpenAPI, runbook.

Integration instructions (quick)

1. Provide the exact target features (e.g. 'transaction search', 'card lock', 'one-click loan').
2. Supply any available developer keys or a authorized test account (we work from customer-authorized access only).
3. We perform a 2–5 day protocol analysis and deliver an integration proposal.
4. After approval, we implement the API, run tests, and deliver code + docs (typical 5–12 business days).
5. Optional: hostable microservice or on-prem connector handed over with CI tests.
