## Description

List valid certificates linked to a customer in a particular country and region.
            
This API is intended to help identify whether a customer has already provided a certificate that
applies to a particular country and region.  This API is intended to help you remind a customer
when they have or have not provided copies of their exemption certificates to you during the sales
order process.
            
If a customer does not have a certificate on file and they wish to provide one, you should send the customer
a CertExpress invitation link so that the customer can upload proof of their exemption certificate.  Please
see the `CreateCertExpressInvitation` API to create an invitation link for this customer.
            
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`.
