Errors - they're hated, yet unavoidable. FTS uses standard HTTP response codes to indicate the success or failure of a request.

Typically, you will receive back 2xx responses to indicate a success, or 4xx to indicate a failure. A response with 5xx code signifies an error within FTS's servers - these are quite rare.

If you run into errors that can't seem to be solved, please contact your account manager or FTS support.

Error Codes

HTTP Response Code Name Description
200 OK The request was successfully handled.
400 Bad Request The request failed, likely due to incorrect or missing parameters.
401 Unauthorized The request is missing an API key, or an invalid one was given.
403 Forbidden Your access token is invalid, expired, or malformed.
404 Not Found The requested resource does not exist.
