Flow messages can be sorted by the following fields, in ascending and descending order:  ascending: &#x60;id&#x60;,  &#x60;name&#x60;, &#x60;created&#x60;, &#x60;updated&#x60; descending: &#x60;-id&#x60;,  &#x60;-name&#x60;, &#x60;-created&#x60;, &#x60;-updated&#x60;  Returns a maximum of 50 flows per request, which can be paginated with offset pagination.
