Outbound Single Sign-on (SuiteSignOn) Access from Your Web Store
The Outbound Single Sign-on feature, also called SuiteSignOn, enables user access to an external application from your web store.
As of the 2025.1 release of NetSuite, the SuiteSignOn feature is no longer supported. If you need an integration using outbound single sign-on, use the NetSuite as OIDC Provider feature. See NetSuite as OIDC Provider.
