Protocol analysis and Open Data integration for multi-account aggregation, transactions, balances, and statements—compliant API or source-code delivery
FNB Allendale Mobile is a free decision-support app by First National Bank of Allendale (Allendale, Illinois) that aggregates all of a user’s financial accounts—including accounts from other institutions—into a single, up-to-the-minute view. In October 2024 the CFPB finalized the Personal Financial Data Rights rule (Section 1033 of the Dodd-Frank Act), which shapes how US banks and data aggregators provide consumer data access; FNB Allendale Mobile’s Grip-powered aggregation aligns with this move toward structured, consent-based data portability. We deliver protocol analysis and usable API implementations so you can integrate transaction history, balance sync, merchant spending data, and tagged transaction metadata in line with Open Banking and GLBA-aligned compliance.

From protocol analysis and authorized data flows, the following data types can be exposed via APIs we deliver. Granularity and use cases are indicative; actual scope depends on app capabilities and user consent.
| Data type | Source (screen / feature) | Granularity | Typical use |
|---|---|---|---|
| Transaction history | Accounts, transaction list, aggregation view | Per transaction, date/amount/description/merchant | Reconciliation, ERP, compliance |
| Account balances | Dashboard, account detail, aggregated view | Per account, real-time or snapshot | Cash flow, aggregation, reporting |
| Merchant spending averages | Spending view, transaction analytics | Per merchant or category | Budgeting, analytics, dashboards |
| Tags, notes, images, geo | Transaction detail, receipt/check attachment | Per transaction, user-added metadata | Search, audit, categorization |
| Alerts and bill notifications | Alerts settings, bill reminders | Per alert rule, upcoming bills | Monitoring, automation, visibility |
| ATM and branch locations | Contact / locator feature | Location list, distance | Branch finder, support integration |
A business or accountant needs FNB Allendale Mobile transaction and balance data in their general ledger or ERP. Our delivered API can provide transaction-history and balance endpoints (with user consent). Data maps to Open Banking: structured transactions with date, amount, counterparty, and optional tags. Flow: User app or portal → auth (Internet Banking credentials) → API → mapping layer → ERP or accounting software.
A user or advisor wants to see FNB Allendale and other linked balances and transactions in one dashboard. We deliver a consent-based API that returns account list, balances, and recent transactions from the aggregation layer. This fits Open Finance: multiple sources in one view. Fields: accounts[], balance, transactions[] with amount, date, description, merchant.
Finance teams or personal-finance tools need merchant spending averages and categorized transaction data. Our implementation can expose spending and transaction endpoints with filters (date range, merchant, tag). Response includes merchant, amount, date, category—aligned with CFPB Section 1033 data portability and minimal retention.
Auditors or compliance officers require exportable transaction data with timestamps, tags, and receipt metadata. We deliver an API that returns transaction lists and optional note/image references (with consent). Use: GLBA-aligned record-keeping, audit support, and evidence of data handling.
Users rely on low-funds alerts and upcoming-bill notifications. Our API can expose alert rules and bill reminders for internal tools that trigger workflows or sync with calendar and task systems—always with explicit consent and minimal data.

We work from client authorization or public/authorized APIs and follow privacy and local regulations. For US banks, we align with the Gramm-Leach-Bliley Act (GLBA) and its Safeguards Rule (protection of customer information, confidentiality, incident response) and with CFPB Section 1033 (October 2024 Personal Financial Data Rights rule on consumer financial data access and API-based data portability). The FDX (Financial Data Exchange) standard is the CFPB-recognized technical specification for US open banking. Community banks under the asset threshold may have phased compliance; all implementations we deliver can support consent records, minimal data retention, and secure transmission.
A typical pipeline we design: (1) Client app (FNB Allendale Mobile or your portal)—user consents and triggers requests. (2) Ingestion / API layer—our delivered service authenticates (e.g. Internet Banking session or token), validates scope, and queries the aggregation and transaction data. (3) Storage or cache (optional)—for aggregation or reporting. (4) Output—JSON/API to your dashboard, ERP, or analytics. Logs and consent are retained for audit.
