idempotencyToken

Alphanumeric string that can be used to distinguish between calls to the IssueCertificate action. Idempotency tokens for IssueCertificate time out after five minutes. Therefore, if you call IssueCertificate multiple times with the same idempotency token within five minutes, Amazon Web Services Private CA recognizes that you are requesting only one certificate and will issue only one. If you change the idempotency token for each call, Amazon Web Services Private CA recognizes that you are requesting multiple certificates.
