# Task types

A task type defines a process that can be executed as a task on a workset. An example of a task type is `Publishing` or `Validation`. There are two types of external tasks:
- Those that are actions (`isAction: true`) associated with a content type or fragment and executed on a single item in a workset.
- Those executed on an entire workset (`isAction: false`). These external tasks can issue callback requests to send tasks.
