Start an Activiti Process via Rest Script in Crafter CMS

Activiti is a powerful open source workflow engine built by Alfresco.  Incorporating a workflow engine into your customer and employee facing sites and portals is an excellent solution for automating complex workflows that cross system boundaries while providing the user with a simple to use, contextual user experience.   Working for a bank or an insurance company and need to workflow contracts with customers?  No problem. Crafter CMS (an open source Java based CMS) paired with Alfresco is a perfect solution.  It’s customer friendly, highly scalable and about as powerful as enterprise technology gets!

In this blog, I’ll demonstrate the most straightforward example of a Crafter CMS REST service being used to start an Activiti Process.


  • You have Activiti ( installed
    The authentication and process are hard coded to simplify the example

Step 1: Create a REST Controller

  • Under Scripts/rest right click and click create controller
    • Enter start-process.get as the controller name
  • Add the following code to the controller. This code assumes Activiti is deployed into the same container as Crafter Engine.


def http = new HTTPBuilder("http://localhost:8080")
def user = "kermit"
def password = "kermit"
def authPair = user + ":" + password
def authEncoded = authPair.bytes.encodeBase64().toString()

http.setHeaders([Authorization: "Basic "+authEncoded])

def ret = null

http.request( Method.POST ) {
    uri.path = "/activiti-rest/service/runtime/process-instances"
    // uri.path = "/activiti-app/api/enterprise/process-instances"

    requestContentType = ContentType.JSON
    body =  [ processDefinitionKey: "vacationRequest", variables:[  [name:"employeeName", value: "Russ"], [name:"numberOfDays", value: "5"],[name:"startDate", value:"10-08-2015 11:11"],[name:"vacationMotivation", value: "rest"]    ]]

    response.success = { resp, reader ->
        ret = reader

return ret

Step 2: Execute the Service

Step 3: Verify that a new process instance has been started
