Connect Arrowhead Credit Union member data and money movement to your stack
Arrowhead Mobile Banking is the iOS and Android app of Arrowhead Credit Union, a California-based federally insured credit union (NCUA). It exposes a rich, member-permissioned data set: linked external accounts, transactions, statements, mobile-deposit checks, Zelle peer-to-peer transfers, savings goals, and spending categories. We help you reach that data through documented, authorized channels with FDX/Plaid-aligned endpoints.
Data available for integration
The table below lists the data objects we extract from Arrowhead Mobile Banking under member authorization, with the screen or feature they originate from, the granularity available, and the typical downstream use case.
| Data object | Source feature | Granularity | Typical use |
|---|---|---|---|
| Account list & balances | Dashboard / Snapshot view | Account-level, current + available, refreshed on demand | Cash-position dashboards, eligibility checks, NSF prevention |
| Linked external accounts | External account aggregation | Institution + masked account number + balance | Net-worth views, multi-bank reporting, household onboarding |
| Transaction history | Account detail / Statement | Per-transaction with date, amount, merchant, category, MCC, pending flag | Bookkeeping sync, expense classification, fraud analytics |
| Statements (PDF) | e-Statements | Monthly PDF with account summary and full ledger | Loan underwriting, audit, regulatory archival |
| Bill-pay payees & payments | Bill Pay | Payee profile, scheduled date, amount, status | AP automation, recurring-payment monitoring |
| Zelle transactions | Transfer & Pay → Zelle | Counterparty (US mobile / email), amount, memo, status | Real-time peer-to-peer reconciliation, refund flows |
| Mobile deposit checks | Mobile Deposit | Image hash, MICR, deposit ID, status, hold release date | Lockbox automation, small-business AR |
| Savings Goals progress | Financial Wellness Tools | Goal target, contributed amount, progress %, milestones | Coaching apps, gamified savings, financial wellness scoring |
| Spending Analysis | Financial Wellness Tools | Aggregated by category and recurring subscription flag | Personal finance management, churn analysis on subscriptions |
| Card controls | Card Management | Card status, temporary-block toggle, last four digits | Lost/stolen workflows, customer-service automation |
Typical integration scenarios
1. Accounting sync for a small business member
A landscaping company keeps its operating account at Arrowhead. Each night an integration calls the transactions endpoint with a 24-hour window, pushes new postings to QuickBooks or Xero, and reconciles Zelle receipts to invoices. Data & APIs: /accounts, /transactions, Zelle webhook. OpenBanking mapping: FDX Accounts and Transactions resources, with the postedTimestamp field driving the incremental cursor.
2. Loan underwriting using statement export
A non-Arrowhead lender needs 90 days of bank activity. The member authorizes export of three monthly e-Statements and the parsed transaction stream. The lender computes inflow stability and DTI, and stores hashed PDFs for audit. Data & APIs: /statements, /transactions?range=90d. OpenBanking mapping: FDX Statements resource, returning a signed download URL.
3. PFM dashboard with Spending Analysis
A budgeting app surfaces Arrowhead Spending Analysis categories alongside categories from other banks. Recurring subscriptions are flagged, and Savings Goals progress is mirrored as a target widget. Data & APIs: /insights/spending, /savings-goals. OpenBanking mapping: derived insights returned as FDX Customer + Account extension fields.
4. Lost-card service automation
An IVR or chat bot calls the card-controls endpoint to apply a temporary block when a member reports a lost card, and follows up with a Secure Message confirming the block. Data & APIs: /cards/{id}/block, /secure-messages. OpenBanking mapping: action-style endpoint guarded by step-up two-factor authentication.
5. Mobile-deposit lockbox for property managers
A property-management platform receives rent checks from tenants. The platform uploads the cheque image through the mobile-deposit ingest endpoint, polls until the hold expires, and posts the cleared amount to the tenant ledger. Data & APIs: /mobile-deposit POST + status webhook. OpenBanking mapping: not part of FDX core today; delivered as a documented Arrowhead-specific extension.

Compliance & privacy
Arrowhead Credit Union is federally insured by the National Credit Union Administration (NCUA), and our integrations follow NCUA cybersecurity guidance plus the CFPB recognition of FDX as a standard-setting body for the Personal Financial Data Rights rule issued in January 2025. Largest institutions face a phased compliance deadline starting April 2026, so endpoints are shaped today to match FDX resource models and consent semantics.
We deliver only authorized or documented public access. Token storage uses encryption at rest, every export carries a consent_id, and PDF statements are hashed before retention. State law touchpoints — California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA) — are honoured for member personal data, alongside Gramm-Leach-Bliley Act safeguards.
Data flow / architecture
The end-to-end pipeline is intentionally short and observable:
- Client app — Arrowhead Mobile Banking on iOS/Android, member authenticates with biometrics or password.
- Ingestion / API gateway — Our adapter calls the documented mobile and FDX-aligned endpoints, attaches the consent token, and normalises responses.
- Storage layer — Append-only event log + relational tables for accounts, transactions, statements; PDFs land in object storage with content-hash keys.
- Analytics / API output — Downstream consumers pull a stable REST or GraphQL surface, or subscribe to webhook streams for Zelle, deposit, and card events.
Market positioning & user profile
Arrowhead Credit Union serves more than 175,000 members, primarily in San Bernardino and Riverside counties of Southern California, with field-of-membership eligibility extended to anyone living, working, worshipping, or attending school in those counties. The Arrowhead Mobile Banking app targets retail consumers and small-business members on iPhone, iPad, and Android phones, with feature parity across mobile and desktop digital banking. Integration buyers are typically US accounting platforms, lenders, PFM apps, and property-tech vendors that want a documented bridge into a regional credit union without rebuilding screen scraping for every member.
