- id überschreiben
POST {{baseUrl}}/api-versio.eventProcessing/1.0/environments/{{environment}}/events HTTP/1.1
Authorization: apiToken {{apiToken}}
Content-Type: application/json
[ // you can create more than one event with one request
{

"utc": 1722601661000 // optional: unix timestamp in milliseconds of the event. If empty, the time of receipt is used
"sourceType":"Qualys", // define the source on the basis of which the event exists; usually the application system (Qualys, Dynatrace, batch job)
"trigger": "192.168.0.102", // which unit triggered the event (e.g. IP address or other ID or hostname)
"externalIdLink":"http://qualys.com?id=EVENT-12345", // optional: external link for further information on the trigger
"externalIdName":"Red Hat CVE detected", // optional: Descriptive name for the trigger
"severity":4, // what is the severity of the event (values between 0-9)
