Looks like asynchronous service calls only.<div style="clear:both;"></div>https://community.appian.com/thread/7955?ContentTypeID=1Sat, 08 Mar 2014 00:42:46 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:3bbe2b75-8ac2-4d3b-bf41-4b3542e88045Stefan HelzleIt is not possible to return any values as this triggers a process that doe possibly run for weeks until completed. So you can start a process via WS from another system. To return any data you need a seperate path like a DB or a WS callback to the other system.<div style="clear:both;"></div>https://community.appian.com/thread/7954?ContentTypeID=1Sat, 08 Mar 2014 00:26:24 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:a69a960b-0883-4bd6-811e-1e33ea996197Jin PhehThanks for the answer guys however you&#39;re both talking about consuming an external service whereas I&#39;m interested in creating a webservice for others to use.<br /><div style="clear:both;"></div>https://community.appian.com/thread/7953?ContentTypeID=1Sat, 08 Mar 2014 00:19:17 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:0851813a-6772-433c-afcc-39d00d166d26Tejas KargutkarYou can use the Call Web Service SS to call a web service and fetch values in return.<br />You may test the smart service using one of the freely available web services from the following link:<br /><a href="http://www.webservicex.net/WS/WSDetails.aspx?CATID=2&amp;WSID=10">www.webservicex.net/.../WSDetails.aspx</a><br />Invoking the above webservice will automatically create data types(<a href="https://forum.appian.com/suite/wiki/74/Call_Web_Service_Smart_Service#Automatically_Creating_Data_Types)">forum.appian.com/.../Call_Web_Service_Smart_Service</a> for you which you can use to store values.<br /><div style="clear:both;"></div>https://community.appian.com/thread/7952?ContentTypeID=1Sat, 08 Mar 2014 00:17:25 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:5263f689-711f-4957-aa4f-6c1b70c1d767Patty IseckeThe Call Web Service Smart Service allows you to integrate data from web services within your process and automatically create a custom data type with it. <br />Checkout:<br /><a href="https://forum.appian.com/suite/wiki/74/Call_Web_Service_Smart_Service#Node_Outputs">forum.appian.com/.../Call_Web_Service_Smart_Service</a><div style="clear:both;"></div>
