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?

NetSuite uses Token-Based Authentication (TBA) or OAuth 2.0. Apideck's Vault guides your users through the authentication setup, securely storing credentials and handling token refresh. We support both authentication methods depending on your customers' NetSuite configuration.

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 has strict concurrency and governance limits. Apideck automatically manages request queuing and retries, ensuring your integration doesn't exceed limits. We optimize API calls to maximize throughput within NetSuite's constraints.
