AWS Certificate Manager Private Certificate Authority
AWS Private Certificate Authority Documentation (API Version 2017-08-22)

GetCertificate

Retrieves a certificate from your private CA. The ARN of the certificate is returned when you call the IssueCertificate operation. You must specify both the ARN of your private CA and the ARN of the issued certificate when calling the GetCertificate operation. You can retrieve the certificate if it is in the ISSUED state. You can call the CreateCertificateAuthorityAuditReport operation to create a report that contains information about all of the certificates issued and revoked by your private CA.
