Return Codes and Errors

The Poken API allows applications to gracefully response to errors by returning HTTP status codes.

With every request a HTTP status code is returned which indicates whether the request was successful or not. If a request was successful the API will return the 200 status code along with the message payload. If the request was not successful then a non-200 status code will be returned with a “response” object which contains the error code(s) and description(s). See the attached schema for the response object.

Possible HTTP status codes:

  • 200 OK – Success
  • 400 Bad Request – The request was invalid.
  • 401 Not Authorized – Authentication credentials were missing or invalid.
  • 403 Forbidden – The request was understood, but it has been refused for some reason.
  • 404 Not Found – The requested URI does not exist.
  • 500 Internal Server Error – Some unexpected error has occurred.
  • 503 Service Unavailable – The API is currently not online

Example error response:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<response xmlns="">
    <description>The alias address provided is already registered.</description>

The error code returned is a unique code which identifies the particular error.
