Beginning April 27, 2019, the Webex Teams platform will require that clients and integrations use the Transport Layer Security (TLS) 1.2 protocol. To align with industry best practices for transport security, the TLS 1.1 encryption protocol will be disabled. TLS 1.0 was disabled on March 17, 2018.

Our internal telemetry indicates that very few clients are using TLS 1.1. To prevent any service disruption between your users or applications and the Webex platform after April 27, please ensure that your Webex Teams clients and API applications' server operating system, libraries, and frameworks support TLS 1.2.

For API developers: If your API applications do not automatically use TLS 1.2, you will need to explicitly configure it. Please consult the documentation for your applications' libraries and frameworks to ensure that they support TLS 1.2. For further information, please visit our developer blog at https://developer.webex.com/blog/webex-platform-disabling-tls-1-1.
