HTTP status codes

For each request, the Lingohub API tries to return suitable HTTP status codes. Response codes for the REST API can be suppressed. Below is a list of status codes that are used:

Code	Name	Meaning
200	OK	Success!
304	Not Modified	No new data was found.
400	Bad Request	Your request was not valid. There will be an explanatory error message.
403	Unauthorized	There are missing or incorrect authentication credentials.
403	Forbidden	Your request was understood but has been refused due to missing rights. An explanatory error message will appear.
404	Not Found	The URI requested is invalid, or the requested resource, a project, for example, does not exist.
406	Not Acceptable	The API will return this code if an invalid format is specified in the request.
429	Too Many Requests	If too many requests are performed quickly, the API rate limit is exceeded, and this code will be returned.
500	Internal Server Error	Please inform the Lingohub Support team, which will investigate the issue as something is damaged.

Error messages

When the Lingohub API returns error messages, it does so in your requested format.
For example, an error from a JSON method might look like this:

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