You can use the REST-API to start up a process or complete a task: http://www.activiti.org/userguide/index.html#N1196B

Hi Frederikheremans,
    I have read the REST-API and find out the "Execute an action" in web scripts ,but I can not understand the parameter  about  "connectorId={connectorId}&artifactId={artifactId}&actionName={artifactActionName}" where and how can I get  parameters ?

Thanks .

Hi,

The action you are referring to is for activiti-cycle. The API's you're looking for are the ones under the Engine, Process, Repository and Management section in the userguide, eg:

Starting a process instance:

Request: POST /process-instance
{
  "processDefinitionId":"financialReport:1"
}

Completing a task:

Request: PUT /task/{taskId}/[claim|complete]
{}



[evan]

So if using the provided example process of "FinancialReportProcess", what should I place for below red color id in order to execute process.

PUT /activiti-rest/service/artifact-action?connectorId={connectorId}&artifactId={artifactId}&actionName={artifactActionName}


   <process name="FinancialReportProcess" id="[color=#0000FF]FinancialReportProcess[/color]" isExecutable="false">
      <startEvent id="[color=#8000FF]StartNoneEvent[/color]" name="[color=#FF00FF]StartNoneEvent[/color]">
         <documentation id="sid-74020069-3909-434e-81f2-fc67f4f578fd">Original Name: "" Original ID: "sid-65A1BDFB-8A62-4BB7-85A7-83375147083E"</documentation>
         <extensionElements>
           
         </extensionElements>
         <outgoing>SequenceFlow</outgoing>
      </startEvent>

To my understand, will it look like as this?
http://localhost:8080/activiti-rest/service/artifact-action?connectorId={FinancialReportProcess}&artifactId={StartNoneEvent}&actionName={StartNoneEvent}

[frederikherema1]

To start the process "FinancialReportProcess", you should call the folowing REST:


POST /process-instance
{
  "processDefinitionId":"FinancialReportProcess:1"
}

and this will return something like the following JSON, indicating the process was started:

{
  "id": "217",
  "processDefinitionId": "financialReport:1",
  "activityNames": ["firstTaskInProcess"],
  "ended": false
}


Please not that the process-definition ID mentioned above assumes there is only one version of the financial process deployed. To get all deployed definition to be sure you use the correct processDefinitionId, you can use:

GET /process-definitions?start=0&size=100
