[API Issue] Technician field remains "null" after assignment

[API Issue] Technician field remains "null" after assignment

Hi Zoho Support / Community,

I'm currently building automation for ticket assignment in ServiceDesk Plus Cloud (API v3). While the assignment API returns a successful response (status_code: 2000), the technician field in the response remains null.

Here’s the request body I used:

{
  "technician": {
    "id": "182916000104896923"
  }
}

✅ What I have verified:

  • The technician ID is correct and active.

  • I am using an API key (or OAuth token) with sufficient permissions.

❓ Question:

Despite a successful assignment, why does the technician field remain "null" in the response?
Is there something else required (e.g. permissions, request status...)

Also, could this be caused by limitations on the client ID or technician role?
