Zoom Contact Center admins can create linked variables - global variables that persist across engagements or flows. You can create linked variables using the Zoom web portal. If the linked variable is unlocked, it can be modified in flows. When the variable is read, it returns the latest value. If the variable is locked, the variable value persists across all engagements where it's referenced and can't be overwritten in the flow.
For example, you can create a linked variable for emergency close / open. If customer wants to set up an emergency close, admin can set a variable globally, so that all flows can then check this variable and decide if it should shut down or remain open based on the variable value.
After creating a custom variable group, you can create a custom variable that belongs to the group.
Value can only be changed by editing this variable: The value can't be updated in a flow. Each engagement will use the value specified in the above setting.
After adding the linked variable, you can reference them in the flow editor.
