API Errors

The Upvest Investment API uses standard HTTP status codes and RFC9457 error types. The following table gives you an overview of all codes and error types.

Usually response codes in the range 2xx indicate a successful response, in the range 4xx a client error and in the range 5xx a server error (these are rare, however).
