kState Credit Union API integration services (FDX / OpenBanking)

Deliverables checklist

• OpenAPI / Swagger specification mapped to FDX entities
• Protocol report on the It's Me 247 / CU*BASE session flow (login, MFA, token refresh)
• Runnable Python and Node.js clients for accounts, transactions, statements and card controls
• Reconciliation samples (QuickBooks, NetSuite, Xero) and Excel/CSV templates
• Test harness with sandbox fixtures and consent-revocation scenarios
• Compliance notes on GLBA, NCUA guidance and CFPB Section 1033

Modules we typically build

• Member authentication and session keepalive against obc.itsme247.com
• Account summary, certificate maturity and loan/credit card snapshot endpoints
• Transaction history with date-range and account-filter parameters
• eStatement PDF retrieval and indexing
• Remote deposit capture (RDC) status webhook
• Debit card on/off and travel notice gateway

1. Personal finance dashboard

A budgeting app needs unified balances across a member's kState CU shares, certificates and Visa card. We expose an FDX-style /accounts endpoint that maps share IDs and loan IDs to depositAccount and loanAccount objects, plus a /accounts/{id}/transactions endpoint for the last 90 days. This is the classic Section 1033 data-portability scenario.

2. Small-business bookkeeping sync

Members who run an LLC through kState CU want nightly pushes into QuickBooks or Xero. We schedule a job that calls /transactions?since=last_sync, normalizes memo lines, and posts to the accounting API with a deterministic external ID so duplicates never appear after a session refresh.

3. Loan servicing & collections

A consumer-lending tool ingests the loan snapshot and credit card minimum-due fields to drive autopay decisioning and member outreach. We surface nextPaymentDueDate, pastDueAmount, and statementBalance, then map them to internal collection states. This avoids screen-scraping the It's Me 247 web UI on a fragile cron job.

4. Audit and lending evidence

Mortgage and SBA underwriters need 24-month statement PDFs with a verifiable chain of custody. We retrieve eStatements through the authorized member session, sign each file with a SHA-256 hash, and deliver them via a webhook to the lender's document vault. FDX payroll/employment fields (added in v6.3) plug in if the member also uses payroll-connected services.

5. Card security automation

A SOC team wants to disable a member's debit card automatically when a high-risk transaction fires. We bridge the in-app card on/off control to a single POST /cards/{id}/state call, and emit a webhook the moment the state changes — so the rest of the security stack stays in sync with what the member sees in the mobile app.

Member authentication (consent + session)

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

{
  "member_id": "******23",
  "password": "<hashed>",
  "mfa_code": "123456",
  "consent_scopes": ["accounts:read", "transactions:read", "statements:read"]
}

200 OK
{

  "refresh_token": "rt_...",
  "expires_in": 1800,
  "consent_id": "csnt_01HZ..."
}

Statement & transaction query (FDX-style)

Remote deposit webhook (server -> client)

US regulatory alignment

Integrations are designed to align with the CFPB Personal Financial Data Rights rule under Section 1033, which the CFPB formally recognised the Financial Data Exchange (FDX) as a standard-setting body for in January 2025. Although small credit unions under $850M in assets are currently exempt from the rule's mandatory implementation timeline, we still ship FDX-shaped objects so a kState CU integration is future-proof if the credit union opts in.

Member consent & data minimization

Every call carries a member-issued consent scope; nothing is fetched outside the explicit grant. Sensitive identifiers (full member numbers, full card PANs) are tokenized at the edge and never persisted. We follow Gramm-Leach-Bliley Act (GLBA) Safeguards Rule expectations for logging, encryption-in-transit (TLS 1.2+) and encryption-at-rest of any cached data.

CommunityAmerica Credit Union

One of the largest credit unions across Kansas and the Kansas City metro. Users who manage both CommunityAmerica and kState CU accounts often need a unified transaction export to drive a single household budget.

Meritrust Credit Union

Wichita-based credit union with a member-friendly mobile app. Integration overlap is similar: balances, transactions and remote deposit status.

Credit Union of America

Operates across Kansas with consumer loans and everyday banking. A typical integration scenario is pulling auto-loan balances alongside kState CU shares for a household net-worth view.

Heartland Credit Union

Also built on the CU*Answers / It's Me 247 stack, which means many of the protocol patterns used for kState CU map cleanly to Heartland's mobile and online banking flows.

Alliant Credit Union

A national credit union frequently named in best-of mobile banking lists. Members who hold both Alliant and kState CU accounts are a common audience for cross-institution dashboards.

Navy Federal Credit Union

The largest US credit union by membership. Useful comparator for any team building FDX-style adapters that must scale across many credit unions.

PenFed Credit Union

Nationally available; strong on lending products. Integration teams often need to merge PenFed loan statements with kState CU share data.

BECU (Boeing Employees Credit Union)

Pacific Northwest credit union with a polished mobile experience. Reference point for transaction enrichment and category tagging conventions.

Mountain America Credit Union

Mountain-West credit union with multi-product members. Their data shape (shares, loans, credit cards) closely mirrors kState CU's, which is helpful when building reusable FDX mappers.
