Errors are returned using standard HTTP error code syntax and any additional information is included in the body of the response, JSON-formatted. Here are some standard API errors:
| Code | Text | Description |
| 400 | Bad Request | The request was invalid and further information is included in the error message. |
| 401 | Unauthorized | The user was not authenticated due to a missing or incorrect API token. |
| 403 | Forbidden | The request is understood but it has been refused or access is not allowed. The error message will contain more information. |
| 404 | Not Found | Resource not found in the specified path. |
| 405 | Method Not Allowed | The type of HTTP request you attempted is not allowed. Check the Allow response header for allowed methods on this resource. |
| 429 | Too Many Requests | The user has sent too many requests in a given amount of time. Check the rate limit headers. |
| 500 | Internal Error | The service encountered an error. Try again later or contact support. |
The following is an example of error code structure from an API call without proper authentication:
{
"errors" : {
"message" : { "Invalid or Missing Authentication"}
}
}
