    Pulling Accountholder Data from Missouri's Jack Henry-Built Community Bank App

    ============================
    INTRODUCTION
    ============================

    St. Johns Bank & Trust Company has served northwest St. Louis and St. Charles County, Missouri since 1926. Family-managed, locally held under parent Unity Bancshares LLC, the bank runs a well-bounded digital footprint: four branches, a Jack Henry Banno-powered mobile app (Android package com.stjohnsbank.grip), and a customer base that does most of its day-to-day banking through that single app.

    For fintech developers, aggregators, PFM tools, and accounting platforms, this smallness is an advantage. The data behind login is tightly scoped — checking, savings, loan products, statement PDFs, mobile-deposit history, bill pay, and account-to-account transfers — with no exotic instrument types to model. The March 2024 platform cutover introduced a new digital-banking experience with unified mobile-and-web design and mandatory two-factor authentication on first sign-in. Any integration targeting the old platform will not authenticate against the current system.

    OpenBanking Studio maps the post-March-2024 surface and delivers a runnable integration — source-code or pay-per-call endpoint — that exposes St. Johns Bank account data through a clean, developer-friendly API layer.

    --------------------
    SUPPORTED API FEATURES
    --------------------

    The St. Johns Bank integration surfaces the full range of data visible to an authenticated accountholder through the Jack Henry Banno app. Key capabilities include:

     Account list and real-time balances across checking and savings products
     Full transaction history with memo, amount, sign, posted and effective dates
     Monthly statement PDF retrieval by billing cycle
     Mobile-deposit history including accepted-deposit list and front/back check images
     Internal and external transfer records — initiated and posted entries
     Bill-pay activity — payee list, scheduled and historical payments
     Alert configuration mirroring — low-balance thresholds and delivery channels
     OpenAPI specification for all exposed endpoints, ready to consume
     Runnable source in Python or Node.js with typed clients and a CLI smoke-tester
     Auth-flow report covering the post-March-2024 login handshake and 2FA capture
     Automated unit and integration tests against a consenting test account
     Compliance and retention notes: no PAN stored, no full statements at rest

    ------------
    INTEGRATION ROUTES
    ------------

    Three delivery paths are available depending on buyer footprint and use case:

    [Route A] Customer-consented session through the app — the accountholder authorizes in writing, supplies credentials and the 2FA factor at first sign-in, and the integration drives the same session a person would. Works for any St. Johns Bank account today without depending on what the bank publishes externally.

    [Route B] Native export baseline — statements export as PDFs and transaction history exports to CSV/QFX from the desktop view. Low-risk baseline for accounting integrations or historical backfill.

    [Route C] Aggregator-mediated open-banking connection — Jack Henry has been migrating Banno-platform institutions onto API-based links with Finicity, Akoya, and Plaid. Applicable when the buyer already holds an aggregator relationship with one of those providers.

    ============================
    USE CASES & APPLICATIONS
    ============================

    [1] Personal Finance Management (PFM) Tools
     Pull real-time balances and categorized transactions into spending dashboards
     Mirror existing low-balance alert thresholds from the bank app into a third-party tool
     Build cash-flow forecasting panels using per-account balance snapshots
     Aggregate St. Johns Bank data alongside accounts from other Missouri community banks

    [2] Accounting and Bookkeeping Platforms
     Import transaction history with memo and category hints for automated reconciliation
     Retrieve monthly statement PDFs for year-end accounting packs and audit collections
     Match mobile-deposit credits to accounts-receivable records for small businesses
     Export to CSV/QFX for legacy bookkeeping tools with no custom parser required

    [3] Lending and Document Collection
     Pull statement PDFs automatically during loan origination document workflows
     Retrieve balance snapshots for income and asset verification
     Access transaction history within configurable date windows for underwriting inputs
     Automate payee and bill-pay history retrieval to verify recurring obligations

    [4] Account Aggregation Services
     Integrate St. Johns Bank alongside Midwest BankCentre, Reliance Bank, and other
    Missouri community banks under a single normalized data contract
     Wire in the Jack Henry Banno open-banking layer via Finicity, Akoya, or Plaid
    for buyers who already hold aggregator relationships with those providers
     Normalize transaction data across community bank formats for unified reporting

    [5] Business Treasury and Operations Platforms
     Cover business checking and savings accounts through a separate authorization scope
     Access ACH batch records, wire entries, and entitlement roles (signer, viewer,
    ACH originator) as a second integration target priced independently from retail
     Monitor scheduled transfers and bill-pay entries for corporate cash-management tools
     Track mobile-deposit history and resulting credits for AR matching workflows

    ============================
    BENEFITS & ADVANTAGES
    ============================

     Customer-consented access — authorization basis rests on the accountholder's own
    consent under Reg E and the bank's online-banking agreement, with a signed record
    kept on file and an explicit revocation path available to the accountholder.

     Post-March-2024 platform coverage — the integration is built against the current
    Jack Henry Banno surface, not the retired prior platform. The auth chain is designed
    to survive minor Banno UI revisions, and a monthly smoke-test job ships with handover.

     No-surprise delivery model — source-code payment is due only after the codebase is
    in your repo, smoke tests pass on your machine, and you have signed off. No upfront
    commitment required.

     Complete deliverables package — OpenAPI spec, auth-flow report, runnable Python or
    Node.js source, automated tests, interface documentation, and compliance notes all
    land in your repository in one handover.

     Retail and business scopes independently priced — smaller buyers are not charged for
    business-banking entitlement plumbing they do not need. The retail path (checking,
    savings, statements) and business path (ACH batches, wires, entitlements) are
    separate line items.

     Aggregator-compatible — for buyers who already plug into Finicity, Akoya, or Plaid,
    the integration can wire in the Jack Henry open-banking connection alongside the
    direct customer-consent route as a parallel path.

     Minimal data footprint by design — the integration deliberately avoids logging
    PANs or storing full statements at rest; compliance and retention notes document
    exactly what is logged, where the consent record lives, and how revocation works.

    ============================
    SUBSCRIPTION PLANS
    ============================

    Two delivery models are available with no long commitment required on either path.

    ------------
    Source-Code Delivery
    ------------

    Starts at $300. Payment is collected only after the codebase is in your repository,
    the smoke tests pass on your machine, and you have signed off on the integration.
    Includes the full deliverables package: OpenAPI spec, auth-flow report, runnable
    source (Python or Node.js), automated tests, Markdown documentation, and compliance
    notes. One to two weeks from kickoff to handover.

    ------------
    Pay-Per-Call Endpoint
    ------------

    No upfront cost. Billed per call against the hosted endpoint. Suited for buyers who
    want to skip the run-ops and maintenance side entirely and consume St. Johns Bank data
    as a managed service. The same data domains are available — balances, transactions,
    statements, deposits, transfers, bill pay — through a documented endpoint with no
    local infrastructure required.

    Business-banking scope (ACH batches, wires, entitlements) is priced separately from
    retail on both delivery models. Contact the team via the engagement page for a
    business-only scope quote.

    ============================
    CONCLUSION
    ============================

    St. Johns Bank represents a well-bounded integration target: a locally held Missouri
    community bank with a clean Jack Henry Banno digital footprint, predictable data
    domains, and a customer base that concentrates its activity on a single mobile app.
    For fintech platforms, aggregators, PFM tools, and accounting systems serving the
    St. Louis metro area or building multi-bank Midwest coverage, pulling this data into
    a normalized API layer is a one-to-two-week effort with clearly scoped deliverables
    and a consent-first authorization model.

    Whether the goal is real-time balance feeds, statement retrieval for lending workflows,
    transaction categorization, or business-treasury coverage, the integration described
    here maps the current post-March-2024 platform surface and ships as runnable code
    ready to drop into your stack.
