How do I integrate NetSuite with my application?

Apideck provides a unified API that simplifies NetSuite integration. Instead of dealing with NetSuite's complex SuiteTalk or REST APIs directly, you integrate once with Apideck and get access to NetSuite along with 20+ other accounting platforms through a single interface.

What NetSuite data is available through Apideck?

Our NetSuite integration covers core accounting entities: invoices, customers, vendors, bills, payments, accounts, and journal entries. We support both NetSuite OneWorld and standard editions, normalizing data across subsidiaries when applicable.

How does Apideck handle NetSuite authentication?

Apideck connects to NetSuite with Token-Based Authentication (TBA), which signs every request OAuth 1.0a style. Vault walks your users through the setup and stores the credentials securely. Oracle stops accepting new TBA integrations from NetSuite 2027.1 and is moving integrations to OAuth 2.0. Apideck will make that change once in the connector for every connected account, so you don't rebuild anything, though your users may need to re-authorize their NetSuite connection.

Can I access custom fields and records in NetSuite?

Yes, Apideck's passthrough feature gives you access to NetSuite's full API capabilities, including custom fields and records. You can use our unified data model for standard entities while accessing custom data through passthrough requests.

What about NetSuite sandbox environments?

Apideck supports connecting to NetSuite sandbox environments for testing. Your users can connect their sandbox accounts through Vault, allowing you to develop and test integrations without affecting production data.

How does Apideck handle NetSuite rate limits?

NetSuite limits concurrent requests per account rather than requests per minute: 5 on Standard, 15 on Premium, 20 on Enterprise and Ultimate, plus 10 per SuiteCloud Plus license. When NetSuite rejects a request for going over the limit, Apideck returns a 429 with normalized rate-limit headers, including x-downstream-ratelimit-reset, so you know when to retry. The Apideck TypeScript SDK retries these automatically; with other SDKs, back off using those headers.
