Element Federal Credit Union API integration (FDX / OpenBanking)

1 · Small-business reconciliation

A West Virginia small business banks with Element FCU for its operating checking account and a vehicle loan. Data nightly pull of /accounts and /transactions?from=…&to=… into QuickBooks Online or Xero. OpenFinance the same export maps 1:1 to FDX Transaction objects, so the business owner avoids manual CSV downloads.

2 · Lender cash-flow underwriting

A community lender needs 90 days of inflows / outflows for a member's loan application. Data /statements for the last three cycles plus /transactions with category hints. OpenFinance output is a normalized cash-flow JSON with average daily balance, NSF count, and recurring deposit detection — the same fields a lender would expect from Plaid Assets or Akoya.

3 · Personal finance & net-worth dashboards

A PFM app already aggregates Chase and Ally accounts and wants to add Element FCU coverage. Data account list, balances, and a 24-month transaction backfill (mirroring Akoya's 24-month window). OpenFinance a single normalized stream feeds the PFM's existing categorization engine so credit-union accounts appear next to bank accounts with no UI change.

4 · RDC status webhook for back office

A property manager collects rent checks deposited via Element's mobile deposit. Data polled or webhook-style notifications when a deposit transitions pending → processed → held → released. OpenFinance downstream AR ledger marks the invoice as paid only after the hold clears, eliminating false "paid" states.

5 · Compliance & audit trail

An RIA serving Element FCU members needs read-only statement archiving for KYC refresh. Data monthly statements via /statements, plus a member-consent record. OpenFinance aligns with NCUA Part 748 and the FDX consent model — consent timestamps, scopes, and revocation events are all logged and exportable.

# Error handling
# - HTTP 401 → token expired, refresh with /auth/refresh
# - HTTP 409 → consent revoked, prompt member to re-authorize
# - HTTP 429 → backoff per Retry-After header (default 30s)

Compliance & privacy

Element Federal Credit Union is a US federally chartered credit union supervised by the National Credit Union Administration (NCUA). Any integration we deliver respects three overlapping frameworks: GLBA Safeguards Rule for member data protection, NCUA Part 748 security program expectations, and CFPB Section 1033 / FDX consent semantics for permissioned data sharing. We use authorized member sessions or documented public APIs only — no screen scraping, no credential reselling.

The CFPB recognized FDX as a standard-setting body in early 2025; implementation of the broader Section 1033 rule was paused in July 2025, but the FDX consent and data-object model is already the de facto pattern used by Akoya, MX, and an increasing share of credit-union cores. Our deliverables ship with consent IDs, scope strings, revocation endpoints, and audit-grade logging so the integration is examination-ready on day one.

Typical modules

• OAuth-style token issuance and refresh
• Account list + balance snapshots
• Posted + pending transactions with paging
• Mobile deposit (RDC) status + webhooks
• Statement PDF + line-item JSON
• Transfer and bill-pay read-only views
• Consent ledger and revocation endpoint

Deliverables checklist

• OpenAPI 3.1 specification for the Element FCU surface (login, accounts, transactions, deposits, statements)
• Protocol & auth flow report (request signing, MFA, token refresh, device binding)
• Runnable Python and Node.js source for the core endpoints
• FDX-shape normalization layer so output drops into existing Plaid / Akoya pipelines
• Automated test suite with sandbox fixtures and replay traces
• Compliance guidance: GLBA, NCUA Part 748, Section 1033 / FDX consent model

Engagement workflow

1. Scope confirmation — endpoints, data depth, region (1–2 days)
2. Protocol analysis and API design (2–5 business days)
3. Build, sandbox validation, FDX mapping (3–8 business days)
4. Docs, samples, and test cases (1–2 business days)
5. Handoff: source code, OpenAPI, consent & compliance notes; typical first delivery 5–15 business days.

• Alliant Credit Union — National digital credit union; rich transaction history and biometric-protected mobile app, often paired with Element FCU in multi-institution aggregation use cases.
• Delta Community Credit Union — Georgia's largest credit union; users often need unified transaction exports across Delta and a secondary credit union account.
• Eastman Credit Union — Top-rated mobile app with quick-balance and smartwatch flows; the data shape is very close to Element FCU's, so adapters can be reused.
• A+ Federal Credit Union — Award-winning member app for Texas members; commonly part of the same aggregation panel.
• Alternatives Federal Credit Union — Community development credit union; relevant when serving members who hold both community and federal credit-union accounts.

• Bethpage Federal Credit Union — Large East Coast credit union; transaction and statement payloads slot into the same FDX mapping used here.
• Credit Union of America — Kansas-based credit union; another typical secondary account for Element FCU members migrating between states.
• Elements Financial — Indiana-based credit union (frequently confused with Element FCU); pair both in coverage if your members search either name.
• U.S. Bank Mobile Banking — Mainstream commercial bank; often the consumer's "other" account next to a credit union, useful for cross-institution reconciliation.
• Ally Bank — Digital-only bank; pair Element FCU data with Ally for full picture of savings + credit-union loans in PFM dashboards.
