Hi, I got this a while back. I dont know that we use any SOPA service. Is there any where i can see what SOAP services we have in NetSuite ?

Your NetSuite account has been identified as currently using one of the unsupported SOAP web services endpoint versions (versions 2017_2 to 2021_1). To ensure the continuity of your web service integrations, and efficient support, you must upgrade to a supported endpoint version as soon as possible.

Is this related to WSDL? There may be an easier way than this but you can view it under setup > integration > manage integrations. Open each one and check under the execution log, there is a column for API version.
