The unique identifier for the version of the message template to update, retrieve information about, or delete.

If you don't specify a value for this parameter, Amazon Pinpoint does the following:
</p>
<ul>
<li>
<p>
For a get operation, retrieves information about the active version of the template.
</p>
</li>
<li>
<p>
For an update operation, saves the updates to (overwrites) the latest existing version of the template, if the
create-new-version parameter isn't used or is set to false.
</p>
</li>
<li>
<p>
For a delete operation, deletes the template, including all versions of the template.
