QuickBooks Online API
Intuit's REST API for QuickBooks Online — read/write invoices, bills, customers, vendors, transactions, and financial reports for the dominant SMB accounting platform.
Viable option — review the tradeoffs
You need to automate invoicing, payments, and financial data sync for SMB customers using the dominant accounting platform.
Reliable CRUD and batch ops for transactions; reports cap at 400k cells (paginate by date); sparse updates prevent overwrites; solid throughput but OAuth refreshes needed.
You want to embed QuickBooks data into CRM, HRIS, fintech, or AI tools without manual exports.
Strong for core SMB accounting flows like CRM→invoice sync; quirks include no batch on lists (customers/items), journal entries for corrections only.
Report Size Caps
Endpoints like BalanceSheet cap at 400k cells; must reduce date ranges or paginate to avoid truncation.
Full Updates Overwrite Fields
Full PUT clears unsent fields; use sparse updates or risk data loss—test in sandbox first.
OAuth 2.0 Expertise
Intuit's auth requires dynamic realm IDs, token refresh logic, and scope management per company.
