Vottus' Response Specification

This spec is for made for JSON responses.

General

• API always returns a Content-Type: application/json header

Status Code

You always send a HTTP code of 200, but there are 2 exceptions:

• Internal Server Error (error kind: internal) - HTTP code 500
• Validation Error (error kind: validation) - HTTP code 400

Successful Response

Successful response passes a success property that is of value true, like so:

{
  "success": true
}

Additionally, when passing data in the response, you may create a data object inside of which you create appropriate property, for example:

{
  "success": true,
  "data": {
    "user": {
    }
  }
}

You may pass multiple properties inside of the data objects. You may also pass a string, boolean, or a different kind of primitive as a value of data properties:

{
  "success": true,
  "data": {
    "user": {
    },
    "loginValidUntil": "2021-01-04T07:19:18.080Z"
  }
}

Failed/Error Response

Response that fails whether because of user input or because of internal error passes a success property that is of value false and an error object with properties "kind" and "message":

{
  "success": true,
  "error": {
    "kind": "user_input",
    "message": "Invalid token"
  }
}

Kind represents the kind of error that occurred or why the error occurred in the first place. Commonly, following kinds are used:

• user_input
  • Meaning that error occurred because of some sort of user input, for example missing/invalid request body/headers
• unauthorized
  • Meaning that the user is not authorized for the endpoint. Eg. not logged in.
  • When the user is however authenticated in some form but is not allowed to perform certain actions, forbidden is used instead!
• forbidden
  • Meaning that user is authenticated but unauthorized to perform certain action.
• internal
  • Internal Server Error. For this kind an HTTP code 500 is sent.
• validation
  • Validation Error. For this kind an HTTP code 400 is sent.

Message is a localized message further describes the error that occurred.
