Webhook Event Example code examples miss "required": […]

[jaller94]

The code example 70 describes several data schemas of "type": "object" with required properties. However, the data schemas don't have the "required": [] array with the names of the required properties.

e.g.

"cancellation": {
  "type": "object",
  "properties": {
    "subscriptionID": {
      "type": "integer",
      "description": "Required subscription ID to cancel subscription.",
      "writeOnly": true
    }
  }
}
