Slipstream uses conventional HTTP response codes to indicate the success or failure of an API request.

In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted). Codes in the 5xx range indicate an error with Slipstream’s servers (these are rare).

Most 4xx errors can be handled programmatically. The error response will include a code that briefly explains the error reported.

  "code": "request.validation.error",
  "message": "The firstname cannot be empty."
