Problem with Scheduling Activities [ Edited ]

[TendenZ]

I see there are 2 endpoints for scheduling activities: api/activities and /api/organizers/{id}/activities.

I've first tried the first one, and that seems to work ok, but the scheduledFor is ignored. I googled and found this topic https://community.act.com/t5/Act-Premium-Web-API/Add-an-activity-for-another-user-different-to-the-A... , in which Simon says... to use the second endpoint (with the organizers).

When I try this, I get back this error (API 1.0.259.0):

{
"message": "An error has occurred.",
"exceptionMessage": "ID Must be at least 36 characters",
"exceptionType": "System.ArgumentException",
"stackTrace": " at act.web.api.Services.ActivityService.Split(String ID) in c:\\gitroot\\act.web.api\\act.web.api\\Services\\ActivityService.cs:line 933

My full request to /api/organizers/6689d53a-6fc8-492e-873a-641e2059ba72/activities :

{
  "startTime": "2018-04-10T09:57:06.638Z",
  "endTime": "2018-04-10T09:57:06.638Z",
  "isTimeless": false,
  "isPrivate": false,
  "activityTypeName": "MijnActivityType",
  "details": "Dit zijn de details11",
  "subject": "Dit is het subject",
  "contacts": [
    {
      "id": "ecc35513-61fd-432a-93e0-99e69d20aad6"
    },
    {
      "id": "6689d53a-6fc8-492e-873a-641e2059ba72"
    }
  ],
  "opportunities": [
    {
      "id": "aa79ccf5-5d00-4f25-be1f-e4cd310ab786"
    }
  ]
}

What am I doing wrong here? I've also tried to add the id of the user to plan for in the "contacts"  array, but this didn't help either.

Yes, the second endpoint is the correct way to post a schedule for activity and your sample that you posted was correct.  Still working on a way to duplicate your issue (no luck yet).  if you have anymore information that could help me duplicate this issue would be appreciated.
