Comments may be left on a variety of object types in Close.

The commenting feature is modeled as threads with comments, where each thread is associated with a specific object and has one or more comments. A comment may not exist without a thread, and a thread may not exist without any comments. Threads are maintained automatically and don't need special consideration when creating or removing individual comments.

Comment bodies are formatted as [rich text](/api/overview/rich-text), and may include basic styling and user/group mentions. The `object_type` of the commented-on object is included in the thread, and should match up with the object types described in the [event log docs](/api/resources/events).
