When a user visits a website, it sends request to a server. The server accepts the request, processes it and returns back with a response with a HTTP header. This HTTP header is inclusive of HTTP Status code.

What is an HTTP status code ?
A status code is a notification/response indicating whether a server request has been completed or not.
These responses are classified into five classes, such as:

• Informational responses error code from 100–199
• Successful responses error code 200–299
• Redirection messages error code 300–399
• Client error responses error code 400–499
• Server error responses 500–599

More commonly received error codes range from 400 or 500.

Occasionally in RIVO, you may get an Error 401 and 500 where the Application has received unexpected input. We have tried to cover every angle but sometimes something slips past.  

Unfortunately, there is a little you can do when you encounter a 500 - an internal server error or a 400 -Bad request error. If it is reproducible, please inform us via Rivo Support so we can plug that gap.
