QuickBooks (via Apideck)

Access QuickBooks through Apideck's Accounting unified API — one of 34 Accounting connectors that share the same method surface. Code you write here ports to Access Financials, Acumatica, banqUP and 30 other Accounting connectors by changing a single serviceId string. Apideck handles auth, pagination, rate limiting, and retries so you don't write per-tenant QuickBooks plumbing.

Quick facts

• Apideck serviceId: quickbooks
• Unified API: Accounting
• Auth type: oauth2
• Gotchas: page
• QuickBooks docs: https://developer.intuit.com/app/developer/qbo/docs
• Homepage: https://quickbooks.intuit.com/

When to use this skill

Activate this skill when the user explicitly wants to work with QuickBooks — for example, "create an invoice in QuickBooks" or "reconcile payments in QuickBooks". This skill teaches the agent:

1. Which Apideck unified API covers QuickBooks (Accounting)
2. The correct serviceId to pass on every call (quickbooks)
3. QuickBooks-specific auth and coverage caveats

For the full method surface (parameters, pagination, filtering), use your language SDK skill:

• apideck-node, apideck-python, apideck-dotnet, apideck-java, apideck-go, apideck-php, or apideck-rest

For the raw OpenAPI spec:

• Accounting: https://specs.apideck.com/accounting.yml · API Explorer

Minimal example (TypeScript)

import { Apideck } from "@apideck/unify";

const apideck = new Apideck({
  apiKey: process.env.APIDECK_API_KEY,
  appId: process.env.APIDECK_APP_ID,
  consumerId: "your-consumer-id",
});

// List invoices in QuickBooks
const { data } = await apideck.accounting.invoices.list({
  serviceId: "quickbooks",
});

Portable across 34 Accounting connectors

The Apideck Accounting unified API exposes the same methods for every connector in its catalog. Switching from QuickBooks to another Accounting connector is a one-string change — no rewrite, no new SDK.

// Today — QuickBooks
await apideck.accounting.invoices.list({ serviceId: "quickbooks" });

// Tomorrow — same code, different connector
await apideck.accounting.invoices.list({ serviceId: "access-financials" });
await apideck.accounting.invoices.list({ serviceId: "acumatica" });

This is the compounding advantage of using Apideck over integrating QuickBooks directly: code against the unified Accounting API once, gain access to every connector in it. New connectors Apideck adds become available to your app without code changes.

QuickBooks via Apideck Accounting

QuickBooks Online is the most widely used SMB accounting connector on Apideck. Coverage is near-complete for core accounting resources.

Entity mapping

QuickBooks entity	Apideck Accounting resource
Invoice	invoices
Bill	bills
Payment	payments
BillPayment	bill-payments
JournalEntry	journal-entries
Account	ledger-accounts
Customer	customers
Vendor	suppliers
Item	items
TaxRate, TaxCode	tax-rates
Company info	company-info
P&L, Balance Sheet reports	profit-and-loss, balance-sheet

Coverage highlights

• ✅ Full CRUD on invoices, bills, payments, customers, suppliers, items
• ✅ Journal entries (create/read)
• ✅ Financial reports: P&L, Balance Sheet, Aged Receivables/Payables
• ✅ Multi-currency — invoices created with currency field route correctly
• ✅ Attachments on invoices/bills via the attachments sub-resource
• ⚠️ Tax rates read-only (QuickBooks requires tax setup through its UI)
• ⚠️ Recurring invoices — not exposed; use Proxy
• ❌ Deposits — use Proxy with the /deposit endpoint
• ❌ Purchase orders — use Proxy

QuickBooks-specific auth notes

• Company/realm selection: QuickBooks is multi-tenant via realmId. The user picks their company during OAuth; the connection is bound to that single realm. Multi-company = one connection per realm (distinct consumerId).
• Sandbox: QuickBooks Sandbox is a separate environment. The user toggles sandbox vs. production during Vault OAuth — connection is bound to whichever was selected.

Common QuickBooks quirks handled by Apideck

• Line items on invoices — QuickBooks uses a nested Line array with DetailType discriminators. Apideck normalizes to line_items[] with unified fields.
• Tax calculation — TotalAmt vs. SubTotal split is exposed as total_amount and sub_total.
• Customer refs — QuickBooks uses CustomerRef.value; Apideck exposes as customer.id.
• Soft-deleted records — Active: false entries. Apideck filters these out by default; pass filter[active]=false to include them.

Example: create an invoice with line items

const { data } = await apideck.accounting.invoices.create({
  serviceId: "quickbooks",
  invoice: {
    customer_id: "12", // QuickBooks customer ID
    invoice_date: "2026-04-18",
    due_date: "2026-05-18",
    line_items: [
      {
        description: "Consulting — April 2026",
        quantity: 10,
        unit_price: 150.0,
        item_id: "7", // QuickBooks Item ID
        tax_rate: { id: "TAX" },
      },
    ],
    currency: "USD",
  },
});

Example: pull P&L report for a date range

P&L is exposed via /accounting/profit-and-loss. See apideck-node for the canonical method signature.

const { data } = await apideck.accounting.profitAndLoss.get({
  serviceId: "quickbooks",
  filter: {
    start_date: "2026-01-01",
    end_date: "2026-03-31",
  },
});

Escape hatch: Proxy API

When an endpoint isn't covered by the Accounting unified API, use Apideck's Proxy to call QuickBooks directly — Apideck injects auth headers and handles token refresh. Set x-apideck-downstream-url to the target endpoint on QuickBooks's own API:

curl 'https://unify.apideck.com/proxy' \
  -H "Authorization: Bearer ${APIDECK_API_KEY}" \
  -H "x-apideck-app-id: ${APIDECK_APP_ID}" \
  -H "x-apideck-consumer-id: ${CONSUMER_ID}" \
  -H "x-apideck-service-id: quickbooks" \
  -H "x-apideck-downstream-url: <target endpoint on QuickBooks>" \
  -H "x-apideck-downstream-method: GET"

See QuickBooks's API docs for available endpoints.
