Passing Variable Workflow in Rest Api with C# Code

Hi All,

I am using rest api in k2 five to start a workflow.

I follow the guide in https://help.k2.com/onlinehelp/k2five/devref/5.0/default.htm#Runtime/WF-REST-API/WF-REST-c.htm

But I need in advance to pass variable workflow when start workflow.

Is it possible to pass varibale workflow in restapi with c# code.

I've already try to use Datafield and XMlField but the variable still didn't filled.

this below Json format that I pass to restapi, but didn't work (category and initiatetype is my variable that I want to pass)

{"expectedDuration":86400,

"folio":"start|K2:K2daniel|20*personal details removed*:10:59",
"priority":1,
"xmlFields":[{"name": "Category","value": "0"},{"name": "InitiateType","value": "CB"}],
"dataFields":{}
}

Is ianyone have already try it? Can I have one example to pass the varibale?

Please your help.

Thx.

Regards,

Daniel
