Before you can use any exemption certificates endpoints, you must set up your company for exemption certificate data storage. Companies that do not have this storage system set up will see CertCaptureNotConfiguredError when they call exemption certificate related APIs. To check if this is set up for a company, call GetCertificateSetup. To request setup of exemption certificate storage for this company, call RequestCertificateSetup.
