Ticket API - Update Ticket to Assign to Group

Hi all,

I am attempting to update a ticket via API to assign it to a group using the group ID.

def update_zd_ticket(url: str, user: str, token: str, zd_ticket: dict, jira_issue: str):

    session = requests.Session()
    session.auth = ("%s/token" % user, token)

    url = f"{url}/api/v2/tickets/{zd_ticket.get('id')}"
    jira_url = f"https://jira.mycompany.com/browse/{jira_issue}"
    payload = {
        "ticket": {
            "comment": {
                "body": f"Jira ticket created: {jira_url}", "public": True
            },
            "group_id": SOME_GROUP_ID_HERE_AS_NUMERIC,
            "status": "open"
        }
    }

    data = json.dumps(payload)

    response = session.request("PUT", url, data=data)

The above code returns 200 status, but the expected update doesn't happen and I am not seeing any message as to why. I am new at this, so I fully expect a face-palm moment, but if some kind soul could please help me out before I lose the hair I have left, I would really appreciate it!

Thanks,
Bruber
