Create an Incedent in Dynamics using REST API

hi

I'm using Nodered to automate flows. During this I try to create an incedent in Dynmaics.

Unfortunately I'm not able to create an incedent
Iuse the following:

msg.payload = {
"title": "Testcase from Chat",
"customerid_account@odata.bind": "/accounts(xxxxxxxxxxxxxxxxxxxxxxxxxxx)",
"primarycontactid@odata.bind": "/contacts(yyyyyyyyyyyyyyyyyyyyyyyyyy)",
"entitlementid@odata.bind": "/entitlements(zzzzzzzzzzzzzzzzzzzzzzzzzz)",
}

msg.url = global.get("dynurl")+"/api/data/v9.2/incidents"

msg.method = "POST"

Does somebody can tell me which fields I have to send to create a new incedent?

And do you have to use an account to create a incedent, or would a contact be enough?

So it would be great to have a list of fields I have to send so that Dynamics will open a new incedent: 

Thanks so much for your help
