This page lists recent and upcoming changes to the Webex Teams REST API. Contact the Webex Developer Support team with any questions.


  • WARNING The Messages API currently accepts @mentions in 1:1 messages. After May 26, 2018, this API will return an error if a message sent to a 1:1 space contains an @mention.


  • All licenses for Hybrid Services which are available for an organization, both enabled and disabled, will now be returned via the Licenses API. Hybrid Services licenses may now be assigned to users before a particular service is activated.


  • MAJOR Beginning March 17, 2018, the Cisco Spark platform will require API clients to use TLS 1.1 or higher. The TLS 1.0 encryption protocol will be disabled on all endpoints to align with industry best practices for transport security. See this blog post for more information.
