The smart service will automatically build the SOAP message for you depending on the requirement of your WSDL.<br /><br />If you wish to build the SOAP message on your own you may need to use a custom smart service such as the Send HTTP Request available for download here in Appian Forum under the &quot;Shared Components&quot; record (<a href="https://forum.appian.com/suite/tempo/records/type/components/view/all)-">forum.appian.com/.../all)-</a> Smart Services<br /><div style="clear:both;"></div>
