Arkansas FCU Mobile Banking API integration & OpenFinance services

Account & balance sync

Pulls the account list (checking, savings, money market, auto loan, home loan, credit card) with current and available balances and the Snapshot pre-login balance view. Used for daily cash-position dashboards and to trigger low-balance alerts inside a budgeting product.

Transaction history API

Returns posted and pending transactions with amount, posted_date, description, merchant, category and running_balance, paged and filterable by date range and account. Used for bookkeeping reconciliation and category-level spend analytics.

e-Statement & document export

Lists available monthly statements and tax documents and fetches each as a PDF plus a parsed JSON summary. Used by lenders and accountants who need 24 months of statement history for income or affordability checks.

Transfers, Zelle® & bill pay

Reads Zelle® send/receive records, internal transfers, external account-to-account transfers and scheduled bill payments with payee, amount, frequency and next run date. Used to build a unified money-movement timeline and to detect duplicate or missed payments.

Card Defend control & events

Surfaces debit and credit card on/off state, merchant and geography limits, and a webhook stream of card-control changes and blocked-transaction events. Used by fraud and risk teams to confirm a card was locked before a disputed charge.

Credit IQ score & report feed

Syncs the daily credit score, monthly credit-report snapshot, monitoring alerts and score-simulator inputs. Used to power a "credit health" panel or to time refinance offers when a member's score crosses a threshold.

1. Bookkeeping & ERP reconciliation

Context: a small-business member runs QuickBooks-style books and wants daily, categorized feeds instead of monthly CSV uploads. Data/API: GET /transactions with account_id and date range, plus GET /statements for month-end reconciliation. OpenFinance mapping: mirrors the Section 1033 "account balance and transaction information" data category — at least 24 months of history with amounts, dates, payment type and merchant name.

2. Lending & affordability checks

Context: a loan origination system needs verified inflows before approving an auto-loan refinance. Data/API: e-statement PDFs plus parsed cash_flow_summary objects and the loan-detail endpoint for current payoff amount. OpenBanking mapping: consumer-permissioned statement sharing — the member authorizes a one-time pull, results are tokenized and the connection is revoked after use.

3. Personal finance & budgeting app

Context: a PFM product wants to show Arkansas FCU accounts next to other institutions in one net-worth view. Data/API: account directory, balances, transactions and the Credit IQ score feed via webhook on each daily refresh. OpenData mapping: read-only aggregation through a documented, consented channel rather than storing the member's banking password.

4. Fraud & dispute evidence

Context: a card-risk team must prove a debit card was locked via Card Defend at the time of a disputed charge. Data/API: Card Defend state endpoint plus the card.control.changed and card.txn.blocked webhooks, correlated with the transaction history feed. OpenFinance mapping: event-driven sharing — state changes pushed in near real time instead of polled.

5. Treasury & multi-account cash dashboard

Context: a member with checking, savings, an auto loan and a credit card wants one screen showing balances, upcoming bill-pay debits and the next loan payment. Data/API: account directory + balances + scheduled bill payments + loan detail, refreshed on a schedule and exported to CSV/Excel. OpenBanking mapping: aggregation of "upcoming bill information" and "terms and conditions" categories alongside balances.

Regulatory alignment

Arkansas Federal Credit Union is a US credit union federally insured by the NCUA, so integrations are framed around US consumer-financial rules. We align with the CFPB's Section 1033 Personal Financial Data Rights ("Open Banking") rule finalized in October 2024 — covered data categories, consumer authorization, and revocation — and with the Gramm-Leach-Bliley Act privacy and safeguards expectations and NCUA guidance. Where the rule's compliance timeline is in flux, we default to consent-based, documented access and revisit scopes as the rulemaking settles.

How we keep it clean

• Member-authorized or documented public/aggregator access only — no credential resale, no covert scraping.
• Consent records and access logs retained for audit; revocation propagates immediately.
• Data minimization: only the fields a use case needs leave the ingestion layer; PII is tokenized at rest.
• Transport encryption end to end; signed webhooks; key rotation and least-privilege scopes.
• NDA and data-processing terms signed on request before any production work.

Deliverables checklist

• API specification (OpenAPI / Swagger) for the agreed endpoints
• Protocol & auth-flow report (token exchange, MFA steps, session refresh, device binding)
• Runnable source for login, transaction sync and statement export (Python / Node.js)
• Webhook receiver sample for Card Defend and transfer events
• Automated tests, Postman collection and integration documentation
• Compliance guidance (Section 1033 data categories, GLBA privacy, consent & retention)

Engagement workflow

1. Scope confirmation: which accounts, data sets and events you need (login, transactions, statements, card events).
2. Protocol analysis and API design — 2 to 5 business days, complexity-dependent.
3. Build and internal validation — 3 to 8 business days.
4. Docs, samples and test cases — 1 to 2 business days.
5. Typical first delivery: 5 to 15 business days; third-party approvals or MFA constraints may extend timelines.

About us

We are an independent technical studio focused on mobile-app protocol analysis and open-data API integration for financial products. Our engineers come from banks, payment processors, data-aggregation platforms and cloud infrastructure, so we know how US credit-union digital banking, the CFPB's open-banking direction, NCUA expectations and multi-vendor privacy rules fit together — and we ship working financial APIs inside those constraints.

• Retail and small-business banking, lending, PFM and fraud/risk integrations
• API gateways, webhook delivery and security reviews
• Custom Python / Node.js / Go SDKs and test harnesses
• Full pipeline: protocol analysis → build → validation → compliance hand-off
• Source-code delivery from $300 — runnable API source plus full documentation; pay after delivery upon satisfaction
• Pay-per-call API billing — use our hosted endpoints and pay only per call, no upfront cost; ideal for usage-based pricing

Tell us the package ID (com.arkansasfcu.arkansasfcu), your use case, and whether you want source-code delivery or pay-per-call access.

What do you need from me to start an Arkansas FCU Mobile Banking integration?

The target app name (provided), the concrete data you need (for example transaction history, account balances, e-statements, Card Defend card-control events, or Credit IQ score updates), and any member-authorized credentials, online banking access, or aggregator sandbox you can legitimately use. We work only with consent-based or documented access.

How long does delivery take?

A first API drop with documentation is usually 5 to 12 business days. Flows that depend on multi-factor authentication, e-statement PDF parsing, or webhook delivery for card events can take longer. We share a milestone plan before any build starts.

How do you handle compliance and member privacy?

We use member-authorized access or documented public/aggregator APIs only, align with CFPB Section 1033 personal financial data rights, NCUA expectations, and GLBA privacy rules, keep consent and access logs, and apply data minimization so only the fields you need are stored or forwarded. NDAs are signed on request.

Can you deliver runnable source code instead of a hosted API?

Yes. The source-code package starts at $300 and includes runnable Python or Node.js services for login, statement export and transaction sync, an OpenAPI spec, automated tests, and a protocol/auth report. We also offer pay-per-call access to our hosted endpoints with no upfront fee for teams that prefer usage-based pricing.
