QuickBooks Online Accounting API for managing invoices, customer payments recorded in the accounting ledger, customers, vendors, accounts, and financial reports. Best for automating bookkeeping, syncing transactions from other systems, generating financial reports, or building integrations that read and write accounting data. Requires OAuth 2.0 with a connected QuickBooks company. API URLs follow the pattern /v3/company//: leave the literal placeholder in the path and the gateway fills in the connected company automatically. This does not cover Intuit Payroll or the separate Intuit Payments API.
12 example endpoints available through Lava’s AI Gateway. See the QuickBooks API docs for full documentation.
This provider requires your own credentials — connect your API key or OAuth account before use.
This is a
catch-all provider — any valid URL under
https://quickbooks.api.intuit.com is supported. Any QuickBooks Online Accounting API endpoint. URLs follow the pattern
https://quickbooks.api.intuit.com/v3/company/{realmId}/{entity} ;. Leave the literal {realmId} placeholder in the path: the gateway automatically substitutes the connected company’s realmId (captured during OAuth connection) from the stored credential, so you never need to look it up. Common accounting entities: invoice, customer, account, payment, bill, vendor, estimate, purchase, journalentry. Use query endpoint for SQL-like queries: /v3/company/{realmId}/query?query=SELECT * FROM Invoice. This provider is scoped to QuickBooks Online Accounting, not Intuit Payroll or the separate Intuit Payments API. See
