DualEntry Public API
REST API for programmatic access to an organization's accounting data across setup (accounts, items, classifications), master data (companies, customers, vendors), transactions (invoices, bills, journal entries, payments, purchase orders), and automation (recurring transactions, attachments). V2 adds depreciation books, intercompany journal entries, and multi-book fixed-asset depreciation. Authenticated with an X-API-KEY header; offset-based pagination; token-bucket rate limiting; signed webhooks for record lifecycle events.
