## Description

List all certificates linked to a customer.
            
A customer object defines information about a person or business that purchases products from your
company.  When you create a tax transaction in AvaTax, you can use the `customerCode` from this
record in your `CreateTransaction` API call.  AvaTax will search for this `customerCode` value and
identify any certificates linked to this `customer` object.  If any certificate applies to the transaction,
AvaTax will record the appropriate elements of the transaction as exempt and link it to the `certificate`.
            
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`.
