If you install my extraRest plugin, then you can use
GET http://{domain-or-ip}/api/1.0/{workspace}/extrarest/session-id to obtain the session ID and append it to the following URL to open the process designer in an external page:
http://{domain-or-ip}/sys{workspace}/en/neoclassic/designer?prj_uid={process-id}&sid={session-id}
If you want to embed the Process Designer in an external web page, then you can use an <iframe> to open the above URL.
This PHP code worked for me to redirect to the Process Designer for editing a process:
Code: Select allfunction redirectToDesigner($oToken) {
global $pmServer, $pmWorkspace;
$processId = '3488462315d48989d598bc8012454964';
$url = "$pmServer/api/1.0/$pmWorkspace/extrarest/session-id";
$oRet = pmRestRequest('GET', $url, null, $oToken->access_token);
if ($oRet->status==200) {
$redirectUrl = "http://localhost:3310/sysworkflow/en/neoclassic/designer?prj_uid=$processId&sid=" .
$oRet->response;
header("location: $redirectUrl");
}
}
