How do I get the error code from an API request into an Appery variable?

[George Van Wormer5962866]

An example is when a user tries to login and it fails. I would like to show them the description of the response from the API. How do I do that?

Also, there is not Appery.io variable. Any variable that you create is a JavaScript variable.
