Successful requests will return a 200 - OK HTTP status code. If the request fails, the response will contain a key error on the top level, and a 4XX or 5XX HTTP status code. Errors are returned as JSON objects in the following format:

{
  "error": {
    "code": 400,
    "type": "bad_request",
    "details": [
      "first_name: Field is required"
    ]
  }
}

The error type will be one of bad_request, not_found, unauthorized, forbidden, rate_limit_exceeded, server_error.
