Identifying the WSDL version for the SOAP Web service update

Sometimes, we need to update the WSDL version for the smooth running of the SOAP integration.

Example:

Recently, for the 2025.1 NetSuite version update, it is scheduled to disable the 2018_1 WSDL version, and it will return the response as “INVALID_VERSION.”

In that scenario, we need to update the old version to the current supporting version to get the expected response.

At most, the version update of SOAP has to be done by the one who sends the SOAP request; we can’t do it on our end.

Changing the version requires updating the version year in each namespace and modifying the fields according to the current version’s availability (mandatory fields, removed fields, etc.).

How can we see the version of the WSDL?

1. In the Integration record (Setup -> Integration -> Manage Integrations)
2. Under the Execution Log, there are SOAP Web Services, REST Web Services, and RESTlets.
3. If the integration gets a response from SOAP in the SOAP Web Services, we can see the version under the API Version column.
