Reaching the data inside Locality Bank's business app

Locality Bank opened in Fort Lauderdale on January 12, 2022, per its launch announcement, and runs its online and mobile banking on Nymbus' cloud-native core — a platform Nymbus describes as API-first, with an OAuth-secured experience layer broken out by use case (customer and account information, money movement, third-party feeds such as Plaid). That architecture decides everything about how its data is reached. The app itself is narrow on purpose: dashboards across a business's accounts, transfers between them, and mobile check deposit. Behind that narrow surface sits commercial deposit and treasury data that an accounting tool, a lender, or a cash-position dashboard would want to pull on a schedule.

The bottom line: this is a consent-permissioned read of a single business's accounts, and the Nymbus core makes a clean token-based path realistic rather than a scrape. Where a sponsor sandbox or a consenting account is available we build against the documented experience-layer endpoints; where it is not, we analyze the mobile app's own authenticated traffic and rebuild the same calls. Both land in the same place — normalized account and transaction records you can query.

What lives behind a Locality business login

The app names very little publicly, so these domains are drawn from what the description advertises and what a Nymbus-cored business account holds. Each is something we model as a distinct record type.

Getting to the data: the routes that apply here

Three routes are realistic for Locality. They are not equal, and the choice depends on what access we can stand up with you.

Consumer/member-permissioned aggregation

The business owner authorizes read access to their own accounts, and the read happens through an FDX-style token flow rather than stored credentials. Reachable: balances, transactions, account identifiers. Effort: moderate; most of it is the consent and token plumbing. Durability: high — token refresh keeps it alive across front-end changes. We set up the consent handshake and the aggregator or direct connection with you as part of the project.

Documented protocol analysis of the app

Under your authorization, we observe the Locality mobile app's own authenticated calls to the Nymbus experience layer and reconstruct them as clean client code — login and token refresh, account fetch, transaction paging. Reachable: anything the app itself shows. Effort: higher up front. Durability: medium — a front-end or core update can shift fields, which is why a re-validation pass is part of how we hand it over.

Native statement export as a fallback

Where the portal offers statement downloads, we parse those into structured records. It is the least real-time of the three and we treat it as a backstop for history, not the primary feed.

For Locality specifically, the permissioned-aggregation route is the one we'd build on. The bank sits on a core that already speaks OAuth and ships account and transaction APIs, so a consented token read is both the cleanest to maintain and the easiest to defend to a supervisor. Protocol analysis is what we fall back to when no sandbox or aggregator path can be arranged in time, and statement parsing fills in deep history.

A statement pull, sketched

Illustrative only — exact paths, scopes and field names are confirmed during the build against the access we set up. The shape follows a Nymbus-style OAuth experience layer.

# 1. Exchange the consented grant for an access token
POST /oauth2/token
  grant_type=authorization_code
  code=<consent_code>            # from the account holder's approval
  client_id=<assigned>  client_secret=<assigned>
-> { "access_token": "...", "expires_in": 900, "refresh_token": "..." }

# 2. List the business's accounts
GET /api/accounts            Authorization: Bearer <access_token>
-> [ { "accountId": "a1", "type": "BUSINESS_CHECKING",
       "available": 18240.55, "current": 18890.55, "currency": "USD" } ]

# 3. Page transactions for one account
GET /api/accounts/a1/transactions?from=2026-01-01&cursor=<next>
-> { "items": [ { "txnId": "t99", "postedDate": "2026-05-29",
       "amount": -412.10, "status": "POSTED", "memo": "ACH DEBIT" } ],
     "nextCursor": "..." }      # follow until null

# Handle 401 by refreshing; treat status=PENDING separately from POSTED

Two details that bite if you skip them: pending and posted entries can both appear, so a naive sum double-counts; and token lifetimes on this kind of layer are short, so the client has to refresh mid-page rather than per-session.

What you receive

Everything is tied to the surfaces above, not a generic template.

• An OpenAPI/Swagger spec covering the auth exchange, account list, transaction paging, transfers and deposit records as we mapped them for Locality.
• A protocol and auth-flow report: the OAuth token and refresh chain, paging and cursor behavior, and the pending-vs-posted handling.
• Runnable source for the key reads in Python and Node.js — token refresh, account fetch, full transaction pagination with retry on 401.
• Automated tests built on recorded fixtures, so a regression run never touches a live balance.
• Interface documentation plus a short compliance and data-retention note: what is logged, what consent record is kept, what gets minimized.

Where integrators use this

• An accounting or tax tool (Locality already partners with one such service) pulling a nightly transaction feed to auto-categorize business expenses.
• A lender or factor verifying a borrower's real-time balance and cash flow before advancing funds.
• A treasury dashboard that consolidates a Locality account alongside accounts at other banks into one cash position.
• A reconciliation job that matches mobile deposits-in-transit against an external ledger and clears them once posted.

Consent and the US data-rights picture

Locality Bank is a Florida state-chartered, FDIC-insured institution, so the FDIC and the Florida Office of Financial Regulation are its supervisors. The read we build rests on one thing: the account holder's own authorization to access their own data. That consent is scoped to the accounts and data types named, carries an expiry, and is revocable — when it lapses or is withdrawn, the token stops working and the sync stops, by design.

The CFPB's Section 1033 Personal Financial Data Rights rule is the obvious forward-looking question for any US bank read. As of this writing it is not in force: a federal court enjoined the CFPB from enforcing the 2024 rule in October 2025, and the agency has reopened it for reconsideration. So we don't lean on 1033 as today's governing framework — we build on the consent basis that already holds, and design the integration so it slots into a permissioned-data regime if and when one is finalized. We operate authorized and documented: consent records kept, access logged, data minimized to what the use case needs, and an NDA where the engagement calls for one.

What we plan for on a Nymbus-cored bank

Two things specific to this app that shape how we build it:

• We design the sync around the short token lifetime the Nymbus experience layer uses, refreshing mid-pagination so a long transaction backfill doesn't die halfway with a 401.
• We separate pending from posted transactions in the schema, because a business treasury read that collapses them mis-states available cash — and we make deposit clearing status a first-class field so deposits-in-transit are visible.
• We wire a re-validation step into handover for the protocol-analysis route, so when the app's front end or the core's fields shift, the breakage is caught by a check rather than by a wrong balance downstream.

Access itself — a sponsor sandbox or a consenting account — is arranged with you during onboarding; it's our step to set up, not a hurdle you clear before we'll start.

Questions integrators ask about Locality Bank

Does Locality running on the Nymbus core change how you reach the data?

It helps. Nymbus exposes an OAuth-secured experience API layer with account and transaction endpoints, so a consenting business account can be read through a documented token flow rather than scraped. We map the exact endpoints and scopes during the build; the customer-facing route stays the same whether the read is consent-permissioned aggregation or analysis of the mobile app's own traffic.

Can you capture the mobile check deposit records, not just balances?

Yes. Mobile deposits and the internal transfers the app advertises both leave server-side records — amount, status, posting date, source and destination account. We model those as their own entities so a deposit that is pending versus cleared is distinguishable in the data you receive, which matters for treasury reconciliation.

Which regulator covers Locality, and does Section 1033 apply to this read?

Locality Bank is a Florida state-chartered, FDIC-insured bank, so the FDIC and the Florida Office of Financial Regulation are the supervisors. The dependable legal basis for the read is the account holder's own authorization. The CFPB's Section 1033 Personal Financial Data Rights rule is not in force — a federal court enjoined enforcement in October 2025 and the CFPB has reopened it — so we treat it as where US open banking may go, not as today's governing rule.

Can you build against a Locality test account instead of live business funds?

That is how we prefer to work. Access is arranged with you during onboarding, and the integration is built and exercised against a sandbox or a consenting low-balance account before it ever touches a live treasury balance. Automated tests run against recorded fixtures so a regression check never moves real money.

Source code lands in your repository from $300, billed only after delivery once you've confirmed it works; if you'd rather not host anything, the same endpoints run as a pay-per-call hosted API with nothing paid up front. Either way the build runs in one to two weeks. Tell us the app and what you want from its data at /contact.html.
