Hi @matthewkrausse, are we sure that Surveys support background processing? Also we usually add the param as a query param to the URL:

        if background_processing:
            url = f"{url}?background_processing=true"

        response = self.api.post_request(url, data=json.dumps(data))

You sure what you wrote is accurate? Did you test that? Or maybe we can just remove the background processing param and logic all together from Surveys?
