Error Codes

Janrain Registration provides access to advanced features through an API that requires only the ability to POST HTTP requests and parse JSON responses. You can use these requests to retrieve contact data, map an identity to multiple accounts, gain access to analytics, and more. The consistent format allows you to communicate with your application and relay the results to your own site.

Response Format

All responses are JSON in the response body with an HTTP 200 response.

All responses include a stat field, for which the valid values are ok or error.

Success Response

The following is an example of a success response, including sample HTTP headers.

HTTP/1.1 200 OK
Cache-Control: no-store
Content-Type: application/json

  "result": {
    "id": "1",
    "firstName": "Robert"
  "stat": "ok"

Error Response

Most error responses appear in the following form:

HTTP/1.1 200 OK
Cache-Control: no-store
Content-Type: application/json

  "code": 100,
  "error": "missing_argument",
  "argument_name": "uuid",
  "error_description": "missing required argument: uuid",
  "stat": "error"

OAuth Error Response

OAuth error responses appear in the following form:

HTTP/1.1 400 Bad Request
Cache-Control: no-store
Content-Type: application/json

  "code": 200,
  "error": "invalid_request",
  "sub_error": "invalid_argument",
  "argument_name": "grant_type",
  "error_description": "invalid grant_type: X",
  "stat": "error"

Error Responses

The error response always contains at least the following fields:

  • code: an integer error code.
  • error: a machine-readable string code.
  • error_description: a text description of the error.

There is a 1-to-1 relationship between the integer codes and the string codes. We provide both for your convenience.

Request Token

Whenever an API call fails (user error or unexpected error), the response includes a field called request_token, which is a generated string of 16 characters. The token is included in our internal API logs. When you submit a support ticket, you should include the request_token so that we can check our logs and find the exact API call and error.

Additional Fields

Some errors may contain additional fields. The error codes and their extra fields are enumerated below.

The error codes are grouped into the following categories:

  • 100: missing argument.
  • 200-399: errors in this range occur when an argument is invalid in some way.
  • 300-399: errors in this range occur when creating, updating or querying records.
  • 340-369: errors in this range occur when a record value violates the schema. 340-359 are for data type errors and 360-379 are for constraint errors.
  • 400-499: authentication and permission errors, including expired tokens or codes and oauth errors.
  • 500: unexpected internal error.

Any code that is a multiple of 100 or 10 is a catch-all for the codes below it, and may be split off into more specific codes in the future. The error codes that are most likely to change are 200, 320, and 330.
