IssueCertificate

The following Java sample shows how to use the IssueCertificate operation.

This operation uses your private certificate authority (CA) to issue an end-entity certificate. This operation returns the Amazon Resource Name (ARN) of the certificate. You can retrieve the certificate by calling the GetCertificate and specifying the ARN.

Your output should be similar to the following:

arn:aws:acm-pca:region:account:certificate-authority/CA_ID/certificate/certificate_ID
