Certificates

GetCertificate

Retrieve a single certificate

Get the current certificate identified by this URL.

A certificate is a document stored in either AvaTax Exemptions or CertCapture. The certificate document can contain information about a customer's eligibility for exemption from sales or use taxes based on criteria you specify when you store the certificate. To view or manage your certificates directly, please log onto the administrative website for the product you purchased.

You can use the $include parameter to fetch the following additional objects for expansion:

customers - Retrieves the list of customers linked to the certificate.
po_numbers - Retrieves all PO numbers tied to the certificate.
attributes - Retrieves all attributes applied to the certificate.
histories - Retrieves the certificate update history
jobs - Retrieves the jobs for this certificate
logs - Retrieves the certificate log
invalid_reasons - Retrieves invalid reasons for this certificate if the certificate is invalid
custom_fields - Retrieves custom fields set for this 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.
