Cannot create servers

[maiden current]

I am trying to create a server through the API. Here is what i have tried but it doesnt seem to work.

Request:

curl --location 'https://panel.guardiancloud.xyz/api/application/servers' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer {REDACTED}' \
--data '{
  "name": "Building",
  "user": 1,
  "egg": 1,
  "docker_image": "quay.io/pterodactyl/core:java",
  "startup": "java -Xms128M -Xmx128M -jar server.jar",
  "environment": {
    "BUNGEE_VERSION": "latest",
    "SERVER_JARFILE": "server.jar"
  },
  "limits": {
    "memory": 128,
    "swap": 0,
    "disk": 512,
    "io": 500,
    "cpu": 100
  },
  "feature_limits": {
    "databases": 5,
    "backups": 1
  },
  "allocation": {
    "default": 17
  }
}'

Response:

{
    "errors": [
        {
            "code": "ValidationException",
            "status": "422",
            "detail": "The selected allocation.default is invalid.",
            "meta": {
                "source_field": "allocation.default",
                "rule": "exists"
            }
        }
    ]
}

I have enough allocations, and resources

Sure, but do you have an allocation with the ID of 17 ?

and is it free?

Is the id just the port?

[frosty olive]

no

So how would I find an allocations id
