Changing the minimum TLS version

To change the minimum TLS version in the ION API user interface:

  1. In the ION API application, select the Configuration tab.
  2. Select General Settings.
  3. Enforce a minimum TLS version from the drop-down.
    Note: The available TLS versions are applicable for communication between ION API and target APIs. This does not apply to communication between authorized apps and ION API.

    Communication with any target APIs using a TLS version lower than TLSv1.3 will not work.
