Protocol analysis and Open Data integration for DNCU balances, transaction history, statements, bill pay, and transfers—compliant API or source-code delivery
Del Norte Credit Union’s Secure Mobile App gives members access to available balances, transaction history, statements, internal and external transfers, bill pay, and mobile check deposit from iOS and Android. In 2025 the app received a redesigned experience (version 4016.2.2) with easier access to frequently used features and updated accounts, mobile deposit, and navigation—aligning with member expectations for data portability. DNCU does not publish a public developer API; we deliver protocol analysis and runnable API implementations so you can integrate balance, transaction, statement, and bill-pay data in line with US credit union data-sharing norms and member consent.

From protocol analysis and authorized data flows, the following data types can be exposed via APIs we deliver. DNCU’s app surfaces balances, transactions, statements, transfers, and bill pay; our implementations map these to structured endpoints for programmatic access. Granularity and use cases are indicative; actual scope depends on app capabilities and member consent.
| Data type | Source (screen / feature) | Granularity | Typical use |
|---|---|---|---|
| Account balances | Accounts overview, account detail | Per account, available/current | Reconciliation, dashboards, aggregation |
| Transaction history | Activity, transaction list, statement | Per transaction, date/amount/type/description | ERP, accounting, compliance, analytics |
| Statements | Statement center, document list | Per statement, period, document link/export | Compliance, audit, record-keeping |
| Internal transfers | Transfer flow, transfer history | Per transfer, amount, date, status, from/to | Cash-flow visibility, audit |
| External transfers & Zelle | External transfer, Zelle | Per transaction, counterparty, status | Payment tracking, reconciliation |
| Bill pay | Bill pay, payees, schedules | Payee list, payment schedule, amount/date | Cash-flow planning, compliance |
| Mobile check deposit | Mobile deposit, deposit history | Per deposit, amount, date, status | Audit trail, balance impact |
| Recurring transfers | Recurring transfer setup | Rule metadata, next date, amount | Automation visibility, reporting |
Businesses and accountants need DNCU transaction and balance data in their general ledger or ERP. We deliver an API that returns transaction history with date, amount, type, and description—and optional balance snapshots—so bookkeeping tools can pull data on a schedule. This maps to Open Finance: structured account and transaction data with member-authorized access; no public DNCU API exists, so our protocol-based implementation fills the gap.
Personal-finance apps (e.g. budgeting or net-worth tools) often aggregate multiple banks and credit unions. Our implementation provides balance and transaction endpoints that return normalized fields (account_id, balance, transactions[] with amount/date/merchant), suitable for the same use cases as Plaid or other aggregators—with the client controlling auth and data retention.
Credit union members and their advisors may need exportable statements and transaction logs for tax or audit purposes. We deliver statement and transaction APIs that support date-range queries and document retrieval, aligned with GLBA and NCUA expectations for member data access. All access is consent-based and auditable.
Treasury or finance teams want visibility into scheduled bill payments and transfer activity. Our API can expose bill-pay payees, scheduled payments, and internal/external transfer history so dashboards show upcoming outflows and completed transfers—with member consent and minimal data retention.
DNCU serves both personal and business members across New Mexico (Los Alamos, Española, Santa Fe, Rio Rancho). Our implementation can support multiple accounts per member and optional business-account flows, returning balance and transaction data per account for consolidated reporting—again with explicit authorization.
Below are illustrative request/response shapes and auth flows. Actual endpoints and fields depend on protocol analysis and client requirements.
// Member login (pseudo)
POST /api/v1/dncu/auth/login
Content-Type: application/json
{ "username": "<MEMBER>", "password": "<PWD>" }
Response 200: { "session_token": "...", "refresh_token": "...", "accounts": [...] }
Response 401: { "error": "invalid_credentials" }
// Session refresh per protocol analysis
// Balance and transaction history (pseudo)
GET /api/v1/dncu/accounts/{account_id}/balance
Authorization: Bearer <SESSION_TOKEN>
GET /api/v1/dncu/accounts/{account_id}/transactions?from=2025-01-01&to=2025-03-12
Response: { "transactions": [...], "next_cursor": "..." }
// Statement list and error handling (pseudo)
GET /api/v1/dncu/statements?account_id=xxx&year=2025
Authorization: Bearer <SESSION_TOKEN>
Response: { "statements": [{ "period": "2025-01", "url": "..." }] }
Error 429: rate limit; retry with backoff
We implement only authorized or member-consented data flows. In the US, credit union data sharing is governed by the Gramm-Leach-Bliley Act (GLBA) and Regulation P (Privacy of Consumer Financial Information). The NCUA (National Credit Union Administration) enforces these for federally insured credit unions: members must receive privacy notices and can opt out of sharing nonpublic personal information with nonaffiliated third parties. Our protocol analysis and API delivery support consent-based access with explicit member authorization; we recommend minimal retention, audit logs, and adherence to NCUA’s Guidelines for Safeguarding Member Information. We do not facilitate unauthorized access or credential sharing.
A typical pipeline we support: (1) Your backend or client app initiates auth using member credentials (or a delegated token). (2) Our delivered API layer handles session refresh and request signing per the app’s protocol. (3) Data is ingested from DNCU’s backend via protocol-compliant calls into your storage or cache. (4) Output can feed accounting software, ERP, personal-finance apps, or internal dashboards. We do not store your end-users’ credentials; you control retention and access.
