Error with API and CURL

[Jibsan Joel Rosa Toirac]

Sorry to keep asking, I made a query with CURL to create a new room but it
doesn't work. It gives me an error. Here is what I did:

curl --location --request POST '
http://192.168.14.98:5080/dialogo/services/room/?sid=da8e90d4-f894-411e-aabd-424502b7c419'
\
--form 'room= {
    "name": "Three",
    "comment": "Test number three",
    "type" : {
    "type": "CONFERENCE";
    }
    "capacity": "100",
    "allowRecording": "true",
    "externalId": "Three",
    "isPublic": "true"
  }'

And this is what the Terminal Throws me:

  Warning: skip unknown form field: }
    "capacity":"100",

Warning: "allowRecording": "true",
    "externalId": "Three",
    "isPublic":
Warning: "true"
  }

Any suggestions?
