--- title: Oracle Netsuite API Integration on Truto slug: netsuite category: Accounting canonical: "https://truto.one/integrations/detail/netsuite/" --- # Oracle Netsuite API Integration on Truto **Category:** Accounting **Status:** Generally available ## Unified APIs ### Unified HRIS API - **Companies** — Companies represent the companies in HRIS - **Employees** — Represents an employee in HRIS - **Groups** — Groups represent the groups for an Employee - **Locations** — Locations represent the locations in HRIS ### Unified User Directory API - **Roles** — The Role object represents a role of a User. - **Users** — The User object represents a User. ### Unified Accounting API - **Accounts** — Account represents bank accounts or a general ledger account - **Company Info** — Company Info represents the company's information - **Contacts** — Contacts represents the company's vendor or a customer - **Currencies** — Currency represents the currencies used by the company - **Employees** — Employee represents an employee of the company - **Expenses** — Expenses represents the expenses of the company - **Invoices** — Invoices represents the invoices of the company - **Items** — Items represents the items of the company - **Journal Entries** — Journal Entries represents the journal entries of the company - **Purchase Orders** — Purchase Orders represents the purchase orders of the company - **Tax Rates** — TaxRates represents the tax rates of the company - **Tracking Categories** — TrackingCategories represents the tracking categories of the company - **Transactions** — Transactions represents the transactions of the company - **Vendor Credits** — VendorCredits represents the vendor credits of the company ## How it works 1. **Link your customer's Oracle Netsuite account.** Use Truto's frontend SDK; we handle every OAuth and API key flow so you don't need to create the OAuth app. 2. **Authentication is automatic.** Truto refreshes tokens, stores credentials securely, and injects them into every API request. 3. **Call Truto's API to reach Oracle Netsuite.** The Proxy API is a 1-to-1 mapping of the Oracle Netsuite API. 4. **Get a unified response format.** Every response uses a single shape, with cursor-based pagination and data in the `result` field. ## Use cases - **Automate expense reconciliation into NetSuite** — Spend management and corporate card platforms can push approved expenses and journal entries directly into NetSuite's general ledger, eliminating manual CSV uploads and ensuring every transaction is tagged with the correct department, class, and location segments. - **Sync invoices and payments for subscription billing** — B2B billing platforms can automatically create invoices in NetSuite when subscriptions renew and record payments when they clear, keeping Accounts Receivable accurate without requiring finance teams to toggle between systems. - **Push payroll journal entries for ledger reconciliation** — HRIS and payroll platforms can map payroll components to NetSuite accounts and push multi-line journal entries after each pay run, with each line tagged to the appropriate tracking categories like department or location for proper cost allocation. - **Streamline procurement with purchase order sync** — Procurement and vendor management tools can push approved purchase orders into NetSuite to commit spend against budgets, while syncing vendor details as contacts to maintain a single source of truth for supplier data. - **Pull Chart of Accounts and segments for transaction coding** — Any SaaS product that generates financial data needs to let end users map their internal categories to NetSuite's accounts and tracking categories. Pulling this reference data ensures transactions are coded correctly and accepted by NetSuite on the first try. ## What you can build - **NetSuite GL account and segment mapper** — Let your users pull their Chart of Accounts, departments, classes, and locations from NetSuite so they can map your product's categories to the right ledger codes before any data is pushed. - **One-click expense push to Accounts Payable** — Automatically push approved employee expenses into NetSuite as expense reports tagged with the correct vendor, account, and tracking categories — no manual re-entry required. - **Automated invoice creation and payment matching** — Generate invoices in NetSuite when your platform triggers a billing event, and record corresponding payments as transactions to close out open receivables. - **Multi-line journal entry posting** — Push balanced, multi-line journal entries into NetSuite's general ledger with full segment tagging, enabling payroll reconciliation, revenue recognition summaries, or any aggregated financial posting. - **Bidirectional customer and vendor sync** — Keep contacts in sync between your product and NetSuite so that invoices, purchase orders, and expenses always reference valid entity records. - **Real-time tax rate and currency lookup** — Pull your users' configured tax rates and enabled currencies from NetSuite to ensure line items are calculated correctly before transactions are created. ## FAQs ### How does authentication work for Oracle NetSuite through Truto? NetSuite supports Token-Based Authentication (TBA) for API access. Truto handles the token exchange and credential storage so your end users can connect their NetSuite accounts securely without your team managing auth flows directly. ### What data can I access through Truto's Unified Accounting API for NetSuite? The Unified Accounting API covers Accounts, Company Info, Contacts, Currencies, Employees, Expenses, Invoices, Items, Journal Entries, Purchase Orders, Tax Rates, Tracking Categories, Transactions, and Vendor Credits. Truto also provides Unified HRIS and User Directory APIs that map to NetSuite's employee and organizational data. ### What are Tracking Categories and why are they critical for NetSuite integrations? Tracking Categories in Truto's Unified Accounting API map to NetSuite's segmentation dimensions — Departments, Classes, Locations, and Subsidiaries. Nearly every journal entry or invoice line item in a mid-market NetSuite instance requires these tags. Without pulling and mapping them, transactions will be rejected by NetSuite. ### Does Truto handle NetSuite's API complexity like pagination and error handling? Yes. NetSuite's SuiteTalk API is notoriously complex, with strict validation on mandatory fields, accounting periods, and subsidiary assignments. Truto abstracts pagination, error handling, and API-specific quirks so your team doesn't have to build and maintain that logic. ### Can I request custom tools or endpoints for NetSuite that aren't in the Unified API? Yes. Truto builds tools on request. If you need access to NetSuite-specific resources like Custom Records, Saved Searches, or advanced transaction types not yet covered by the Unified API, you can request them and Truto will build support. ### Does the integration support NetSuite OneWorld (multi-subsidiary)? The Unified Accounting API exposes Company Info and Tracking Categories, which map to NetSuite's subsidiary structure. This allows your users to select the correct subsidiary context when coding transactions, which is essential for OneWorld accounts. ## Related reading - [A Practical NetSuite Migration Guide: Moving Off SOAP Before 2028](https://truto.one/blog/a-practical-netsuite-migration-guide-moving-off-soap-before-2028/) — Oracle is deprecating NetSuite SOAP APIs by 2028.
