What's the best way to check for an error response? If, for example, you make an API call that succeeds, but the request itself is an error, how should I check?
For example, if you try to create a new invoice when there is a pre-existing approved invoice, the entire API call itself "succeeds" but returns an error, which passes the is_object test that is at the bottom of the readme sample.
The return code looks like this:
SimpleXMLElement Object
