# createCustomerEvent

> Creates a customer event that appears in the timeline of every thread belonging to the customer.
Use this to surface important product activity (e.g. a failed payment, a deleted API key) so
your team has full context when helping the customer. The event layout is defined using Plain UI
components. Requires the `customerEvent:create` permission.
