HTTP status codes

The LingoHub API returns standard HTTP status codes for every request. These codes indicate the success or failure of an API operation.

Code	Name	Meaning
200	OK	The request was successful.
304	Not Modified	The resource has not changed since the last request.
400	Bad Request	The request is invalid. Review the accompanying error message for details.
401	Unauthorized	Authentication credentials are missing or incorrect.
403	Forbidden	The server understood the request but refuses to authorize it due to insufficient permissions.
404	Not Found	The requested URI is invalid, or the resource (such as a project) does not exist.
406	Not Acceptable	The request specified an invalid format.
429	Too Many Requests	The API rate limit was exceeded. Reduce the frequency of your requests.
500	Internal Server Error	An unexpected error occurred on the server. Please contact LingoHub Support to investigate the issue.

Error messages

The LingoHub API returns error messages in the format requested (e.g., JSON).

The following example shows an error response in JSON format:

{  
  "error": "The 'page_size' parameter must be between 1 and 100 but was -1"  
}
