Hi Nigel,

Please find below an example:

function Get-BasicAuthCreds {
    param([string]$Username,[string]$Password)
    $AuthString = "{0}:{1}" -f $Username,$Password
    $AuthBytes  = [System.Text.Encoding]::Ascii.GetBytes($AuthString)
    return [Convert]::ToBase64String($AuthBytes)
}
$BasicCreds = Get-BasicAuthCreds -Username "evt.integration" -Password "ServiceN0w!"
$body = '{	"records":	
[
     {
     "source":"SCOM",
     "event_class":"SCOM 2007 on scom.server.com",
     "resource":"C:",
     "node":"name.of.node.com",
     "metric_name":"Percentage Logical Disk Free Space",
     "type":"Disk space",
     "severity":"4",
     "description":"The disk C: on computer V-W2K8-dfg.dfg.com is running out of disk space. The value that exceeded the threshold is 41% free space.",
     "additional_info":""
      }     
   ]
}'
Invoke-WebRequest -Uri "http://localhost:9082/api/mid/em/jsonv2" -Headers @{"Authorization"="Basic $BasicCreds"} -ContentType "application/json" -Method Post -Body $body

Hi natasciaheil,

No.. This is a bad practice when it comes to Event Management, you should either:

a. Post event against the instance Event Management web service API

https://<instancename>.service-now.com/api/global/em/jsonv2

b. Post event against MID WebService Event Collector

http://{MID_Server_IP}:{MID_Web_Server_Port}/api/mid/em/jsonv2

Jef,

Quick question for you why is it best practice to use that API? What makes it any different then going directly to the event table? I'm not saying you are wrong I am just curious the reason for this as I've never been able to get that answered by someone. Thanks.

Thanks for the response. Is there an example using API Key Credentials?
