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.
|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.|
FTS recommends writing your code to handle the various errors that can occur.
