Route 31 Credit Union API integration (FDX / OpenBanking)

Deliverables checklist

• OpenAPI 3.1 / Swagger specification covering accounts, transactions, transfers, RDC and card controls
• Protocol & auth flow report (OAuth 2.0, OIDC, biometric enrollment, token refresh, MFA prompts)
• Runnable Python and Node.js source for login, account list, transaction export, statement download, and RDC submission
• Postman collection, automated tests, and a 30-page integration handbook
• Compliance briefing on CFPB Section 1033, FDX, NCUA examiner expectations, Reg CC / Reg E, and member-permissioned data sharing

Engagement model

Two ways to work with us, each priced separately. Pick the one that matches how you ship.

• Source-code delivery from $300 — fixed scope, runnable code plus docs, paid on acceptance after delivery.
• Pay-per-call hosted API — call our hosted endpoint, pay only per request; no upfront fee, ideal for pilots and low-volume back-office sync.

1. Small-business reconciliation for Muskegon-area members

A local accountant onboards Route 31 Credit Union member-business clients to a QuickBooks-compatible PFM. Data used: account list, 13 months of transactions, share-draft check images. Mapping: our Statement API normalises records to FDX Transaction objects, then pushes them into the accounting tool nightly via a webhook.

2. Member-permissioned loan underwriting

An auto lender requests 90-day cashflow during a refinance. Flow: member taps "Share with lender", an OAuth consent screen is shown, the lender's app receives a scoped access token and pulls balances and inflow / outflow categorisation. OpenBanking mapping: Section 1033-aligned consent receipt, FDX Account + Transaction envelopes, no credential storage.

3. Automated mobile check deposit pipeline

A community business wants to clear customer cheques without staff retyping data. Flow: the user captures a cheque inside our wrapper, MiSnap-style image quality is enforced client-side, and our RDC API submits the deposit, polls status, and emits deposit.accepted or deposit.held webhook events for the back office.

4. Card-control automation for fraud teams

A risk operations console mirrors the in-app card lock toggle. Data: card state, last 4, recent CNP transactions. API: POST /cards/:id/lock with a documented audit reason; GET /cards/:id/events returns lock / unlock / replacement history that can feed a SIEM.

5. Multi-credit-union dashboard for households

A household holds Route 31 Credit Union accounts plus accounts at a larger institution. Flow: our connector returns FDX-shaped account and transaction objects, so the dashboard merges them with feeds from other credit unions without per-institution mapping code. This is exactly the unified-view pattern Section 1033 was written to enable.

Member sign-in & token refresh

Account list & transaction export

// 2. List accounts and pull a transaction window

U.S. open banking framework

Every Route 31 Credit Union integration we ship is designed against the CFPB's 12 CFR Part 1033 Personal Financial Data Rights rule (final rule effective January 17, 2025; tiered compliance dates from April 1, 2026 through April 1, 2030). The CFPB's January 2025 recognition of Financial Data Exchange (FDX) as a standard-setting body anchors our data shapes — by Q1 2025 over 114 million U.S. consumer accounts were already connected via FDX-aligned APIs, so we standardise on those Account, Transaction, and Statement objects rather than re-inventing schemas.

Credit-union-specific guardrails

• NCUA Examiner's Guide expectations for Remote Deposit Capture risk programs and member suitability reviews
• Regulation CC funds-availability holds surfaced explicitly in the RDC response envelope
• Regulation E electronic-transfer disclosures and dispute logging for transfers and bill pay
• OAuth 2.0 + OIDC token flows; no plaintext credential storage; consent receipts retained per data-minimization defaults
• Optional state-level overlays (Michigan privacy, GLBA Safeguards Rule) when the deployment requires it

CFCU Community Credit Union

An upstate-New-York community credit union app with balances, transfers, mobile check deposit and bill pay. Members frequently appear in shared accounting tools alongside Route 31 Credit Union members, so a unified transaction export is a common ask.

Eastman Credit Union

One of the highest-rated U.S. credit-union mobile apps. Holds the same shape of share / certificate / loan data, which makes it an obvious second-source for reconciliation pipelines that need redundancy across institutions.

Delta Community Credit Union

Georgia's largest credit union, with a deeply used mobile app covering Touch ID sign-in, transfers and mobile check deposit. Cross-institution PFM tools that already pull Delta data can typically slot a Route 31 Credit Union connector in without schema changes.

Mountain America Credit Union

Operates across Utah, Idaho, Arizona, Montana and Nevada, with Zelle, mobile check deposit and loan applications surfaced in-app. Shares an FDX-aligned view of transactions, balances and statements similar to what we expose for Route 31 Credit Union.

Navy Federal Credit Union

The largest U.S. credit union by membership. Often acts as a household member's "primary" while Route 31 Credit Union holds local share or auto-loan accounts; aggregators routinely need both feeds in one wallet view.

PenFed Credit Union

The fourth-largest U.S. federal credit union with a digital-first member experience. PenFed's app covers checking, savings, share certificates and loans — precisely the entity types our Route 31 Credit Union integration normalises into FDX Account objects.

UW Credit Union

An FDX member institution. UW Credit Union's participation in the standards body is one reason Section 1033 deployments increasingly assume FDX-shaped feeds — making the same shape useful for Route 31 Credit Union work.

Servus Credit Union

A large Canadian credit union and FDX member. Cross-border Canadian / U.S. household analytics often combine Servus data with U.S. credit-union data such as Route 31 Credit Union, which is straightforward when both speak FDX.
