How to get the current List GUID within your SharePoint Designer Workflow

You can get the Current List GUID by following the 4 simple steps below within your SharePoint Designer Workflow:

1) Use the "Extract substring from End of String" Action to copy 108 characters from the end of the Workflow Context: Workflow Status URL (Output to Variable:WorkflowStatusURLWithListGUID)


2) Use the "Extract substring from Start of String" Action to copy 44 characters from start of the WorkflowStatusURLWithListGUID (Output to Variable:ListGUID)

3) You can now use the Workflow Variable ListGUID within your custom actions or to construct dynamic strings where Current List GUID is required

For e.g. A Common use of the List GUID is when using workflows associated with SharePoint Calendar list and there is a requirement to export the SharePoint Event to *.ics file (so that the SharePoint Event can be added by user to his/her personal Outlook Calendar). To do this add a hyperlink to a URL similar to this within email Action:

<insert workflow context: current site url>/_vti_bin/owssvr.dll?CS=109&Cmd=Display&List=<insert List GUID here>&CacheControl=1&ID=<insert current item id here>&Using=event.ics
