Each API call returns an HTTP status code that reflects the nature of the response. We have done our best to follow the [HTTP status code](https://en.wikipedia.org/wiki/List_of_HTTP_status_codes) conventions.Any request that did not succeed will return a 4xx or 5xx error. The 4xx range means there was a problem with the request, like a missing parameter. The 5xx range means that something went wrong on our end.Salesmachine API returns the following codes:
