Drop a component. Set six properties. Query your QuickBooks data with TFDQuery, TFDTable, and every DataSet method you already know — no REST wrapper, no new API to learn. OAuth2 is handled automatically.
The NxFireDAC QBO Driver bridges Intuit QuickBooks Online and the Embarcadero FireDAC framework — no wrappers, no custom APIs, no compromises.
NxFireDACQboDriverLink is a proprietary custom FireDAC physical driver for Embarcadero RAD Studio. It gives Delphi and C++ Builder developers direct, native access to Intuit QuickBooks Online data using the same familiar components they already know. The driver ships as a compiled BPL that links into both Delphi and C++ Builder projects without modification — no source conversion required.
Unlike REST wrapper libraries that require learning a new API, this driver works exactly like any other
FireDAC database driver. Drop a TNxPhysQBODriverLink component on your form, configure
a TFDConnection with a handful of properties, and your QBO company data is immediately
available as a standard FireDAC dataset.
Reading customers, invoices, items, and 27 other QBO entities is as simple as a SELECT
statement. Creating and updating records uses the same ExecSQL pattern you already use
with SQL Server, PostgreSQL, or any other FireDAC database. All standard DataSet methods are available —
FieldByName, ParamByName, First, Next, Prior, Last, and more.
OAuth2 authentication is handled automatically by the driver on first connect. After the user authorizes the application in their browser, tokens are securely stored and refreshed automatically — your application code never touches an OAuth token directly.
Works with every FireDAC-aware component you already own: TFDQuery, TFDTable, TDBGrid, TDBNavigator, TFDMemTable, report tools, third-party grids — anything that speaks FireDAC speaks QBO.
The driver manages the complete Intuit OAuth2 flow on first connect. Tokens are stored securely and refreshed automatically in the background. Your application never handles a token directly — ever.
Query QBO data with standard SELECT statements and write records with INSERT / UPDATE via ExecSQL — the same pattern used against SQL Server, PostgreSQL, or SQLite. No new API surface to master.
All standard DataSet navigation and filtering methods work as expected: FieldByName, ParamByName, First, Next, Prior, Last, Locate, Filter, and more.
Toggle between Intuit Sandbox and Production environments with a single property — no code changes, no recompile. Ship a single binary that works in both contexts.
The driver ships as a compiled BPL targeting RAD Studio 13 Florence (BDS 37.0). It links natively into both Delphi and C++ Builder projects — drop the component, reference the BPL, and your C++ code calls the same FireDAC API. No source conversion, no wrappers, no extra steps.
Full license holders receive all updates and upgrades for the lifetime of the component — at no additional cost beyond the monthly subscription. Intuit API changes are tracked and addressed promptly.
