<p>
Returns the history of the specified execution as a list of events. By default, the results are returned in
ascending order of the <code>timeStamp</code> of the events. Use the <code>reverseOrder</code> parameter to get
the latest events first.
</p>
<p>
If <code>nextToken</code> is returned, there are more results available. The value of <code>nextToken</code> is a
unique pagination token for each page. Make the call again using the returned token to retrieve the next page.
Keep all other arguments unchanged. Each pagination token expires after 24 hours. Using an expired pagination
token will return an <i>HTTP 400 InvalidToken</i> error.

This API action is not supported by <code>EXPRESS</code> state machines.
