• Login token updates:

  • reset totp
  • enabling totp
  • enabling email 2fa
  • logout current sessions
  • logging out other clients
  • crowd log in

• omnichannel use cases:

  • set and unset void extensions
  • livechat status through:
    • business hours
    • LivechatTyped.setUserStatusLivechat
    • user logout
    • new agent
    • removed agent

• apps engine use cases

  • user creation
  • user update

• user updates:

  • updates from REST API
  • activate and deactivate
  • username change
  • new and updated banners
  • banners read
  • language change
  • user preferences
  • sidebar preferences
  • status changes
    • irc quit and connect
