# Read a discussion thread

One internal thread with its roster, its resolved state and the caller's unread count. Addressed by the THREAD, with no row id in the path, because a thread id already names one record and repeating it would let the two disagree. The messages are a separate read.

Access class: `def:read`.

## Endpoint

| Name | In | Type | Required |
