Data available for integration

Typical integration scenarios

1. Accounting and bookkeeping

Businesses and individuals already use Hana Bank USA’s Direct Connect with QuickBooks® and Quicken®. Our API or protocol implementation extends this: automated transaction pull by date range, mapping to categories, and export to Excel or JSON for custom ledgers and multi-bank aggregation.

2. Personal finance and dashboards

Aggregate balances and transactions from Hana Bank USA with other accounts. Use balance sync and transaction history APIs to power net-worth views, spending analytics, and budget alerts—aligned with consumer data rights under CFPB Section 1033.

3. Compliance and audit

Export transaction logs and statement data for internal audit or regulatory review. Data pipeline: app or authorized session → ingestion API → secure storage → report generation. Fields include date, amount, counterparty, and optional tags/notes.

4. Business treasury

Multi-account balance and payment initiation for small and mid-size businesses. Use account list and balance APIs for daily liquidity views; map transfer flows to initiate payments or verify completion via transaction history.

5. Lending and affordability

With user consent, balance and transaction history support income and expense verification for loan applications. Open Banking-style access to balances and transaction metadata (no raw credentials) supports compliant affordability checks.

Technical implementation

Below are illustrative request/response shapes and auth flows. Actual endpoints depend on protocol analysis and client environment.

Session / login (pseudo-code)

POST /api/v1/auth/session
Content-Type: application/json

{
  "username": "<ONLINE_BANKING_ID>",
  "password": "<REDACTED>",
  "device_id": "<DEVICE_FINGERPRINT>"
}

Response: {
  "access_token": "eyJ...",
  "refresh_token": "...",
  "expires_in": 3600,
  "requires_2fa": false
}

Transaction history (pseudo-code)

GET /api/v1/accounts/{accountId}/transactions
  ?from=2025-01-01&to=2025-01-31&limit=100

Authorization: Bearer <ACCESS_TOKEN>

Response: {
  "items": [
    {
      "id": "tx_001",
      "date": "2025-01-15",
      "amount": -125.00,
      "description": "Bill Pay - Utility",

Statement / webhook (pseudo-code)

Content-Type: application/json
Authorization: Bearer <ACCESS_TOKEN>

{ "account_id": "acc_xxx", "month": "2025-01" }

Response: { "job_id": "stmt_001", "status": "pending" }

// Webhook on completion (callback URL registered)
POST <CALLBACK_URL>
{ "job_id": "stmt_001", "status": "ready", "url": "https://..." }

Data flow and architecture

A typical pipeline: (1) Client app or authorized third party initiates access using secure credentials or tokens. (2) Ingestion layer calls our delivered API or protocol implementation, which communicates with the bank’s app or backend under user authorization. (3) Data is normalized and stored in your secure environment (database or data lake). (4) Outputs: analytics, reports, ERP feeds, or downstream APIs. We do not retain your customer data; you control storage and retention.

Compliance and privacy

Implementations are designed to align with applicable US regulations. The CFPB’s Personal Financial Data Rights rule (Section 1033 of the Dodd-Frank Act), finalized in October 2024, requires covered institutions to make consumer financial data available to consumers and authorized third parties securely. We follow user authorization and minimal data use; no selling of data or targeted advertising. Hana Bank USA, N.A. is Member FDIC; we respect FDIC-related disclosure and privacy expectations and recommend you maintain consent records and data retention policies.

Market positioning and user profile

Hana Bank USA serves consumers and businesses in the US, with branches in New York, New Jersey, and Los Angeles, as part of Hana Financial Group (Korea). Primary users include Korean-American communities and businesses seeking FDIC-insured deposits, remittance, SBA loans, and digital banking. The app is available on iOS and Android (package us.kebhana.grip), with two-factor authentication and biometric sign-in. Related institutions in the Korean-American banking space include Woori America Bank and Bank of Hope, which offer similar deposit and digital services; our integration work focuses on Hana Bank USA’s data and flows rather than cross-bank comparison.

In 2024–2025 the app was updated (e.g. iOS 3.22.0) with continued security enhancements and usability improvements. The parent group’s “Hana API On” platform underscores the group’s commitment to open API and fintech integration; we deliver complementary protocol analysis and implementation for the US mobile app and its data.
