API Response Codes

The TN360 API uses HTTP response codes to indicate error states.

Response Categories

There are three main groups of response codes:

Response Category Meaning
2xx success response codes indicates a successful API call. This may include an empty response if no additional data is available.
4xx error status codes indicate an error related to the information provided on the API call (e.g., a required parameter is missing)
5xx error status codes indicate TN360 server errors.

Standard Error Code Responses

Response code Meaning
200 The API call was successful
204 No data is available
400 Bad request. This error is likely the result of an incorrect request (eg. a missing parameter).
401 The call is unauthorised. Either the API key is invalid or expired, or you are trying to access an object that is not authorised by this key
404 The specific object is not found. This could be an incorrect URL or an unknown resource (in which case additional error information will be provided in the HTTP response)
500 Internal server error. TeletracNavman staff will be investigating.
