Connect American First Mobile balances, statements and mobile deposits to your back office

American First Mobile is the digital channel for an American First Credit Union member account. The app surfaces balances, posted and pending transactions, scheduled bill payments, internal and external transfers, mobile remote-deposit-capture (RDC) checks, and push alerts. We turn that surface into stable, documented APIs you can call from accounting, ERP, treasury, or compliance systems.

Account login & session APIs — Member-authorized OAuth-style flow with token refresh, MFA echo, and session pinning. Useful for personal-finance dashboards, household budgeting tools, and small-business bookkeeping bots.
Balances & statement export — Real-time available, current and pending balances per share/checking/loan account, plus paged transaction history with date ranges, MCC tags, and CSV/JSON/OFX/PDF exports for reconciliation.
Mobile remote deposit capture — Programmatic check deposit pipeline: front/back image submission, MICR parsing, auto-capture metadata, deposit limit checks, and status webhooks (received → review → cleared / rejected).
Bill pay, transfers & alerts — Schedule and cancel one-time or recurring bill payments, A2A internal transfers, external ACH, and subscribe to instant alerts for posted transactions, low balances and security events.

What we deliver

Each engagement produces a self-contained kit so your engineering team is not locked into us. The kit covers protocol research, runnable code, configuration, and operational guidance — and is reviewable by your security team before any production traffic flows.

Deliverables checklist

  • OpenAPI 3.1 specification covering login, accounts, transactions, deposits, transfers, and webhooks
  • Protocol & auth-flow report (TLS pinning notes, OAuth/refresh token chain, device-binding fields)
  • Runnable Python and Node.js reference clients with retry, backoff, and idempotency logic
  • Postman collection plus signed-webhook receiver sample (HMAC-SHA256)
  • Compliance pack: consent template, retention schedule, Section 1033 mapping, GLBA safeguarding checklist
  • Automated end-to-end tests against a sandbox tenant or a controlled fixture set

Engagement models

  • Source-code delivery from $300 — runnable API source plus full documentation; pay after delivery once integration tests pass.
  • Pay-per-call hosted API — call our endpoints with your members' authorization; pricing is metered per request, no upfront fee, ideal for ramp-up periods.
  • Optional retainer for protocol updates whenever the credit-union releases a new app version.

Data available for integration

The table below summarizes the OpenData surface we expose for an authorized American First Mobile member account. Each row reflects a distinct data type, the in-app source it is derived from, the granularity available, and a typical downstream use. Use this as the starting point for your integration scope.

Typical integration scenarios

Below are end-to-end flows our customers most often run on top of American First Mobile data. Each scenario names the business context, the data or API involved, and how it maps to the broader OpenBanking model.

1. Personal-finance dashboard sync

Context: a budgeting app wants to show a member their full credit-union picture in a unified view. Data: /accounts, /transactions, balance webhooks. Mapping: equivalent to a Section 1033 "data access" request — consumer-authorized retrieval of consumer financial data through a documented channel rather than screen scraping.

2. Small-business accounting reconciliation

Context: a sole proprietor uses American First Mobile for business banking and wants nightly reconciliation in QuickBooks Online. Data: paged transactions with MCC tags, ACH trace IDs, mobile-deposit clearance events. Mapping: standard OpenBanking AISP-style read flow with a daily delta job.

3. Mobile remote-deposit pipeline

Context: a property-management firm receives rent checks at multiple sites and wants to automate deposits without driving to a branch. Data: image upload endpoint, MICR parsing, auto-capture metadata, status webhook. Mapping: payment-initiation analog where the "initiation" is RDC rather than ACH push.

4. Treasury sweep across institutions

Context: a household with American First plus an external broker wants to sweep idle balances above a threshold. Data: real-time balance, internal A2A transfer, external ACH transfer. Mapping: rules engine that consumes balance webhooks and writes back through transfer endpoints.

5. Compliance and audit pack

Context: a fiduciary needs a 7-year audit pack of statements and tax forms. Data: e-Statements PDFs, 1099-INT, 1098, alert log export. Mapping: read-only data right under Section 1033 with retention-aware archiving and SHA-256 chain-of-custody hashes.

Technical implementation

The samples below illustrate the shape of the APIs we deliver. They are pseudo-code with realistic field names and headers; the production version uses TLS 1.3, certificate pinning where applicable, and replay-protected request signing.

Compliance & privacy

Regulatory anchors

Credit-union data export in the United States sits inside several overlapping regimes. Our deliverables are mapped to each one explicitly, so your legal and information-security teams can audit them line by line.

  • CFPB Section 1033 (Personal Financial Data Rights) — final rule effective 2025-01-17 with phased compliance dates running through 2030; reopened for reconsideration in August 2025. We follow the documented "developer interface" model and supply consent records that match the rule's representative and authorization tests. See the CFPB Personal Financial Data Rights page.
  • NCUA cybersecurity guidance for federally-insured credit unions — applied to our key handling, logging, and incident-response runbooks.
  • GLBA Safeguards Rule — least-privilege scopes, encryption-at-rest, and vendor-management documentation.
  • PCI DSS v4 when card-PAN material is in scope (we default to tokenization and avoid raw PAN whenever possible).

Privacy-by-design defaults

  • Member consent recorded with timestamp, scope, IP, and device fingerprint
  • Data minimization: scopes are issued field-by-field, not "read everything"
  • Configurable retention windows (default 13 months for transactions, 7 years for tax forms)
  • Right-to-revoke: a single endpoint that purges tokens, webhook subscriptions, and cached data
  • Authorized public APIs only; no credential-scraping fallback in production

Data flow / architecture

The pipeline is intentionally short, because every extra hop is one more place a member's data could leak. A typical deployment looks like this:

  • 1. Client app or browser — the member completes a consent screen and authorizes scopes.
  • 2. OpenFinance Lab gateway — performs the OAuth-style handshake with American First Mobile, stores refresh tokens encrypted with AWS KMS or your own KMS, and issues short-lived access tokens to your backend.
  • 3. Storage / event bus — Postgres for relational data (accounts, transactions), object storage for statement PDFs and check images, plus a Kafka or SQS topic for real-time events.
  • 4. Your business systems — accounting, ERP, BI, or risk engine consumes the API and webhooks.

Market positioning & user profile

American First Mobile is positioned as a member-first credit-union app rather than a fintech challenger. Its primary users are U.S. credit-union members — predominantly retail consumers in the western United States and small-business owners — who want a familiar, secure mobile channel for everyday banking. The app supports both Android and iOS and is distributed through the Google Play Store and Apple App Store; a recent industry shift across U.S. credit unions is the rollout of fully-digital business account opening, mirroring announcements such as the 2025 launch of digital business onboarding by peer institutions. The audience leans toward members who value relationship banking, lower fees, and federally-insured deposit accounts (NCUA-backed) over the higher-yield, app-only models popularized by Chime or Varo, which makes structured API access especially valuable to bookkeeping, household-finance, and treasury platforms that want to serve credit-union households without writing screen scrapers.

Similar apps & integration landscape

The credit-union and digital-banking landscape in the United States is fragmented across thousands of institutions and a dozen leading digital-bank apps. Teams that integrate American First Mobile typically need to handle data from peer apps too. The list below is purely informational; we do not rank or criticize these apps — we frame each one as a node in the broader OpenBanking ecosystem.

Credit-union peers

  • Alliant Credit Union — frequently ranked at the top of digital credit unions; holds checking, savings, and high-yield certificate balances. Customers integrating American First often need a unified transaction export across both apps.
  • BECU — the Boeing Employees Credit Union; large Pacific Northwest member base with similar balance and statement data shapes.
  • Eastman Credit Union — Tennessee-headquartered with a highly-rated mobile app; common in cross-state household integrations.
  • Delta Community Credit Union — large Atlanta-based credit union; carries the same RDC, bill-pay, and Zelle data domains.
  • Heritage Financial Credit Union — appears as a peer in competitor research; emphasizes member loans and shared-branch transactions.
  • KeyPoint Credit Union — California-based credit union frequently listed as a substitute; relevant for households living near American First branches.

Digital-bank challengers

  • Chime — fintech checking and savings; users who keep a Chime account next to American First often want consolidated cash-flow reporting.
  • Ally Bank — full-service online bank; deposit, savings, and brokerage data complements American First's loan and member-share data nicely in budgeting tools.
  • Capital One Mobile — large issuer-and-bank app; commonly federated alongside credit-union accounts for credit-card payoff workflows.
  • Discover Bank — high-yield savings and checking; users with a Discover account plus American First commonly need cross-bank ACH automation.

FAQ

What do you need from me to start an American First Mobile integration?

The target app name (American First Mobile, package com.americanfirstcu.americanfirstcu), a list of concrete needs (account login, balances, transaction history, mobile check deposit, bill pay, transfers, alerts), and any existing member credentials, sandbox access, or third-party aggregator keys you already hold.

How long does delivery take for a credit union mobile API?

Usually 5–12 business days for a first API drop covering login, balances and statements, plus documentation. Mobile-deposit and webhook flows for instant alerts add 3–5 business days. Highly bespoke or multi-channel stacks may take longer.

How do you handle compliance when extracting credit union data?

We work only under documented authorized channels: signed member consent, OAuth-style flows that mirror the app, or aggregator partnerships. Implementations follow CFPB Section 1033 personal financial data rights, GLBA safeguarding requirements, NCUA guidance, and PCI DSS where card data is in scope. We provide consent logs, data minimization rules, and retention schedules.

Can I receive real-time alerts for transactions and deposits?

Yes. We expose a webhook channel that fires on posted transactions, mobile-deposit status changes, low-balance thresholds, and bill-pay confirmations. Each event is signed with HMAC-SHA256 and includes an idempotency key so your downstream ledger or accounting system can deduplicate.
📱 Original app overview (American First Mobile — appendix)

The new and improved American First Mobile App is designed to offer seamless, secure and convenient access to your finances anytime, anywhere. Exclusively for valued American First Credit Union members, the app comes packed with advanced security features and current-generation technology to ensure that mobile banking is always safe and efficient.

Key features of the American First Mobile App as documented by the publisher:

  • View Account Balances and Transactions — stay on top of your finances with real-time updates.
  • Mobile Check Deposit — deposit checks easily using your phone's camera.
  • Bill Pay — manage and pay your bills quickly and securely.
  • Money Transfers — effortlessly transfer funds between your accounts.
  • Instant Alerts — receive notifications about account activity.

American First Credit Union is a member-owned not-for-profit financial cooperative that, like all federally-insured credit unions, is regulated under the National Credit Union Administration (NCUA) framework. Mobile banking deepens the member relationship by extending balance lookups, RDC, bill pay and transfers to a phone-first surface, and the app remains the most actively used digital channel for the credit union's everyday personal-finance, household, and small-business members.

This page illustrates how that surface can be turned into a documented, authorized API set under OpenData/OpenFinance/OpenBanking principles. American First Mobile, its logos, and any registered trademarks are the property of American First Credit Union; this page is a sample integration positioning written by an independent technical service studio.
