SOAP API - Get the default Value of an external Input of an User-Interaction

Hi Guys,

I'm trying to get the Default-Value of a external Input of a User-Interaction.

My Testworkflow only has a start and end, in the middle there is a "User Interaction" with two external Inputs. One of the externals Inputs has via Presentation a Default value.

This default value is what I want to get via SOAP for Scripting

Everything I can figure out with the Method "getWorkflowInputForWorkflowTokenId" is the following:

    [getWorkflowInputForWorkflowTokenIdReturn] => stdClass Object        (            [id] => 2c961dc145ccc05e0145e0baae600c7a            [workflowTokenId] => 2c961dc145ccc05e0145e0baadd40c77            [name] => myWorkflowName : TestInteraction            [description] => Description der Interaction            [parameters] => stdClass Object                (                    [item] => Array                        (                            [0] => stdClass Object                                (                                    [name] => externalInputString                                    [type] => string                                )                            [1] => stdClass Object                                (                                    [name] => externalInputNumber                                    [type] => number                                )                        )                )            [attributes] =>            [state] => 0            [creationDate] => 20140509132501+0200            [xmlContent] => 

Is it possible to get this Value? (even with REST-API? <= I didn't find it there as well)

Thanks,

Marc
