"We developed a SMART on FHIR URL Redirect App. We have the Application ID and the Client ID, but I was wondering if their should be a non-production Application ID and/or a non-production Client ID for testing purposes. With other EHR vendors we have created this type of application, we were provided a non-production Client ID for testing purposes. Is there a non-production Application ID and/or a non-production Client ID for testing purposes."
