All Cornerstone SOAP APIs except Transcript APIs (/webservices/LMS/LOWS.asmx), will be deprecated in Q4 of 2023. This will impact only a subset of API customers. If you are impacted by this upcoming change, you will receive an email from Cornerstone in November 2022 with information detailing the actions you will need to take prior to this deprecation.

To provide better API functionality and experience, Cornerstone has migrated almost all APIs to REST APIs.
