Beginning on Monday, February 28th, we will be enforcing the use of TLS1.2 or above for all API calls. If you have an API connection with MC Professional (fka Oasis), you are likely already using TLS1.2 or above. However, if you are not sure please reach out to your internal team, IT team, or developer that created the API connection.
Note: This only applies if you are using our open API. Unsure? Login as an ASA and go to settings > account settings > click "API management" at the top right. If you see anything listed here, you are likely using our API. If it's for the MC Job Board or LMS/Classroom, you can disregard this notice. For anything else, please contact the creator/developer of the API integration to be sure all calls are using TLS1.2 or above.
