How to create a change task using powershell

[Francez]

Hi Team,
I'm trying to create a change task using a powershell script. I was already successful for the change record creation, but when I try to create a change task nothing happens.

$ChgNumber='CHG0127576'
$Sys_ID='2230b72b1b4bdc106f662f876e4bcb53' #this is the sysid of the change record
$Uri1 = "https://nameofcustomer.service-now.com/api/now/table/task"

# Specify HTTP Method
$Method1 = "POST"
# Specify Request Body

$BodyTask = @{
priority = "3 - Medium"
assigned_to = "Name of the assignee"
u_task_type = "Implementation"
u_vendor = "Vendor_CORP"
assignment_group = "VENDOR-QUEUE"
short_description = "Implementation - $ChgNumber - Execute this task before"
description = "Long Description Long Description"
work_notes = "Change Created to Vendor_Corp"
}

$BodyJson_Task = $BodyTask | ConvertTo-Json

$Response1 = Invoke-WebRequest -Headers $header -Method $Method1 -Uri $Uri1 -Body $BodyJson_Task -ContentType "application/json"

$JsonPUT1 = $Response1 | ConvertFrom-Json
$PUTObject1 = $JsonPUT1.result

$Response1 = Invoke-WebRequest -Credential $SNowCreds -Headers $Header -Method 'GET' -Uri $Uri1  -ContentType "application/json"

I received the response below
StatusCode        : 201
StatusDescription : Created
Content           : {}
RawContent        : HTTP/1.1 201 Created
                    X-Is-Logged-In: true

RawContentLength  : 0

But when I look the tasks for the change, no one was created. Any Help Please.

Hi,

Along with the 201 and response headers, you should also receive a response body which details the created record. As you're not defining the sys_class_name in your body, you're likely creating tasks directly on the task table rather than the child change_task table.

Hi Kieran,

Thanks for replying back.

I included the fields sys_class_name, change_request and the sys_id. On the URL I also changed to $Uri1 = "https://<<nameofinstance>>.service-now.com/api/now/table/sc_task"

$BodyTask = @{

sys_class_name = "change_task"

change_request = 'CHG0127581'
sys_id = '7b1a8e801bab94d06f662f876e4bcb64'
priority = "3 - Medium"
assigned_to = "Name of the assignee"
u_task_type = "Implementation"
u_vendor = "Vendor_CORP"
assignment_group = "VENDOR-QUEUE"
short_description = "Implementation - $ChgNumber - Execute this task before"
description = "Long Description Long Description"
work_notes = "Change Created to Vendor_Corp"
}

And now I got this message (403) Forbidden. Since I was able to create a change record, I suppose my authentication it is correct. I believe I don't have permission to modify the table for changes tasks.
Am I doing this right?
