Error handling

For HTTP error codes 400 and 422 the response body will contain:

• error_type: a short description code
• error_codes: a list of more detailed codes

Error codes and error types can be formatted as follows:

• {error}
• {target/attribute}__{error}
• {nested_object}__{object_attribute}__{error}

{
  "error_type": "invalid_request",
  "error_codes": [
    "birth_date__invalid_format",
    "first_name__required",
    "phone_number__country_code__invalid"
  ]
}
