Hi @HulisaniN ,

Thanks for responding. I think my question was not very clear. What I am trying to do is calling K2 REST API to start a workflow instance. We are following this part of documentation for this purpose. https://help.k2.com/onlinehelp/k2five/DevRef/current/default.htm#Runtime/WF-REST-API/WF-REST-API.htm%3FTocPath%3DRuntime%2520APIs%2520and%2520Services%7CWorkflow%7CWorkflow%2520REST%2520API%7C_____0

Our eventual goal is to create K2 workflow instances from an external web application, but for now we are trying to call this service using POSTMAN. I am having issue passing values for Smart Object in ItemReferences, the documentation provided at https://help.k2.com/onlinehelp/k2five/DevRef/current/default.htm#Runtime/WF-REST-API/Workflow-REST-API-Item-References.htm%3FTocPath%3DRuntime%2520APIs%2520and%2520Services%7CWorkflow%7CWorkflow%2520REST%2520API%7CWorkflow%2520REST%2520API%2520Samples%7C_____4  tells me to pass an ID to the smart object, but I don't know how to get that id. 

Right now, an object is created in result of my API call from postman, but data is not being populated there. And clicking on that form shows error for the data object. I am attaching screenshots for the error message as well as REST API call from POSTMAN. Please let me know if anything else is needed to look into this?

Regards,

@HulisaniN 

Thanks for responding. We have already seen those articles but they are of little help because they are not starting workflow using API. In our case, process workflow works fine when we do it manually, but gives error when calling via REST API. We are using K2 FIVE 5.3 version. If there are any examples for how to fix this error while calling from API, will highly appreciate that help.

Regards,
