Integrate QuickBooks Without an API
QuickBooks has an API. Getting access to it is a different story.
To use the QuickBooks Online API in production, you need an Intuit developer account, an OAuth 2.0 integration, and approval through Intuit’s app review process before your customers can connect. For QuickBooks Desktop, the barriers are steeper — a separate SDK, a local server component, and a fundamentally different authentication model from the cloud version.
For teams that need accounting data from customer QuickBooks accounts — invoices, expenses, reports, payroll summaries — the API path requires significant engineering work before a single record moves. Deck provides a faster alternative: connect to any QuickBooks account through the web interface, with no developer setup, no OAuth configuration, and no Intuit app review required.
What Deck handles on QuickBooks
- Invoice and accounts receivable extraction — pull open invoices, payment status, and aging summaries from any QuickBooks account on demand or on a schedule
- Expense and accounts payable sync — extract vendor bills, expense transactions, and payment records without building an API integration
- Profit & loss and balance sheet reports — retrieve financial statements in structured format for downstream reporting or reconciliation workflows
- Chart of accounts — sync the full account list and category structure across entities or fiscal periods
- Customer and vendor records — extract contact data, payment terms, and transaction history for CRM or billing system sync
- Payroll and tax data — pull payroll summaries, tax liabilities, and withholding records from QuickBooks Payroll accounts

Get started in 3 steps
- Connect your customer’s QuickBooks account — your customer authenticates through Deck’s secure flow. Deck Vault stores credentials and handles session management, including multi-factor authentication, automatically.
- Define the data you need — specify which reports, records, or transactions to extract and how often. Deck maps the QuickBooks data structure to your format.
- Call Deck’s API — retrieve QuickBooks data on demand or on a schedule through a single endpoint, without maintaining a direct QuickBooks integration.
FAQ
Does QuickBooks have a public API?
QuickBooks Online has a REST API, but production access requires an Intuit developer account, OAuth 2.0 configuration, and app review. QuickBooks Desktop uses a separate SDK with a different authentication model. Deck bypasses both by connecting through the QuickBooks web interface directly.
What QuickBooks data can Deck extract?
Deck can pull invoices, expenses, vendor bills, financial reports (P&L, balance sheet, cash flow), chart of accounts, customer and vendor records, payroll summaries, and tax documents — anything accessible through the QuickBooks web interface.
Does Deck work with both QuickBooks Online and QuickBooks Desktop?
Yes. Deck connects to both versions through their respective web interfaces, without requiring separate SDKs or integration configurations for each.
Can Deck connect to multiple QuickBooks company files?
Yes. Deck handles multi-entity QuickBooks setups, pulling data from multiple company files or accounts through a single integration.
How does Deck handle QuickBooks MFA?
Deck Vault stores authentication credentials and handles multi-factor authentication automatically, so your integration continues working without manual re-authentication when sessions expire.
