# Get conversation item

> Returns a single call or SMS message by its ID.

<Note>
  **Required scope:** `CONVERSATIONS_READ`
</Note>

## Item ID format

* Call IDs start with `cll-` (e.g., `cll-abc123`)
* Message IDs start with `msg-` (e.g., `msg-def456`)

Passing an ID with an unrecognized prefix returns a `400` error with code `INVALID_ITEM_ID`.
