NetSuite is Actively Retiring Legacy Systems Across 3 Core Pillars
NLAuth and older TBA methods are restricted for new connections. All external API traffic must migrate to OAuth 2.0 immediately.
The entire legacy XML/SOAP protocol is being shut down. Third-party integrations must rebuild on modern REST Web Services to avoid total data pipeline failure.
Outdated business logic will permanently stop executing. Custom scripts must be refactored to SuiteScript 2.1 standards before hard cutoffs.
