How to start a process from a JavaScript action

var processInstanceId = startActivitiProcess (processId, obj);

processId: process id

This value can be retrieved from the list of the processes or from the Web Modeler. Example: in the "Execution process list" you can see all the processes. To be more precise, all the versions for all the processes, where a specific process version is expressed as:
SIN<YOURCOMPANY_ID>_YOUR_COMPANY_ID><YOURPROCESS_ID>:<VERSION>:<INTERNAL_ID>
The processId to specify must NOT include version and internal id, so it must be something like:
SIN<YOUR_COMPANY_ID>_YOUR_COMPANY_ID><YOUR_PROCESS_ID>

obj: Javascript object containing variables declared in the start event and required in order to start the process.

More precisely, if you have defined variables like MY_EMAIL_ADDRESS and MY_NAME, then the javascript object should contain something like:
{ myEmailAddress: “…”, myName: “…” }
that is to say, variable names must be expressed in "camel-case".

Note: the start variable is a boolean value representing the outcome of the process start.

Example

var obj = \{
  requestDate: new Date(),
  docId: vo.documentId,
  requestId: vo.requestId,
  initiator: vo.requestUserId
\};

var processInstanceId = null;
try \{
  processInstanceId = startActivitiProcess("PROCESS_ID",obj);
\}
catch(e) \{
  // in case of failure when attempting to start a process, an exception is fired here: e.toString() contains the error message
\}
