# createThreadEvent

> Creates a thread event that appears only in the timeline of the specified thread.
Use this when an activity is specific to a single conversation rather than the customer
as a whole. The event layout is defined using Plain UI components. Thread events are visible
only to your team and are never shown to the customer. Requires the `threadEvent:create` and
`threadEvent:read` permissions.
