Oracle NetSuite provides product support for SOAP web services endpoints and associated WSDL's 3 years from their release. Additional endpoint versions from the previous releases are also available, however are provided without any product support. When your account is upgraded to version 2026.1, oldest unsupported endpoint version 2019.1 will be retired.
To ensure that your web service-based integrations continue to work, you must upgrade to a later endpoint before your account is upgraded to NetSuite Release 2026.1. As a general recommendation, any customers who are using an unsupported version are advised to upgrade to the latest WSDL version.
When Will this Change Occur?
The 2019.1 SOAP web services endpoint will be retired in all of your accounts when they are upgraded to NetSuite Release 2026.1, which are scheduled to take place between middle of February and end of April of this year.
What is Changing?
Access to URLs for all retired WSDL versions will be disabled upon upgrade to 2026.1. Any SOAP operation that makes use of a retired WSDL will return a response of "INVALID_VERSION". This response will return for SOAP web service-based integrations, as well as single sign-on (inbound SSO) and SuiteSignOn (outbound SSO) integrations that use SOAP web services APIs.
Recommended Actions
Please update all of your client applications to use the latest generally available WSDL version before your accounts are upgraded to the 2026.1 release. Install Application Performance Management SuiteApp from the Marketplace to see which unsupported endpoint versions you use.
