I have developed a scoped app, which calls 3rd party APIs using RestMessageV2. The said 3rd party have discontinued their support for TLS 1.0, and going forward will be supporting TLS 1.2 only. 

Is there a way to find out which TLS version is used by Servicenow's RestMessageV2 when sending an outbound request? Does it use TLS 1.0 or 1.1 or 1.2?

If in Chrome, go to More Tools -> Developer Tools -> Security Tab, and it will show a "Secure Connection" information.

You will see something similar to :
 
 
 
 
Connection - secure (strong TLS 1.2)
The connection to this site is encrypted and authenticated using TLS 1.2 (a strong protocol), ECDHE_RSA with P-256 (a strong key exchange), and AES_128_GCM (a strong cipher).
