The QuickBooks Online Accounting API is Intuit's REST API for reading and writing the core accounting entities of a QuickBooks Online company file, including customers, vendors, items, invoices, bills, payments, accounts, journal entries, and tax codes. Apps authenticate via OAuth 2.0 against the Intuit Developer platform and target a per-company realm using https://quickbooks.api.intuit.com/v3/company/{realmId} in production or the sandbox host for testing. It is the foundation API for accounting, bookkeeping, invoicing, and financial reporting integrations on QuickBooks Online.
