The Solaris API uses conventional HTTP response codes to indicate the outcome of an API request. Response codes can be grouped into the following categories:

  • 2xx: The request was successful.
  • 4xx: An error occurred due to the information provided, e.g., missing or incorrect parameters.
  • 5xx: Those errors are returned if there was an error in Solaris servers.

Solaris API error responses all follow a standard format. They include the HTTP response code, the reason for the error, and a unique ID for use with Solaris customer support.

List of error codes

Most model validation errors result in invalid_model errors (as opposed to validation_error errors) and contain a message that explains the cause of the error.


The Solaris API will return different errors at different stages of the validation process, which may abort the process. For example, it will raise a 403 Forbidden or 404 Not Found error before validating any models. If this happens, then the API will not return any information about invalid model attributes.
