Key Management Service:PutSecretValue

Last Updated:Jul 29, 2025

Stores a new version of a secret value for a generic secret.

Operation description

  • For information about the access policy required for a RAM user or RAM role to call this OpenAPI operation, see Resource Access Management.

  • This operation supports only generic secrets. Each generic secret can have a maximum of 10 versions. If the number of versions exceeds the limit, KMS deletes the earliest version.

  • By default, the new secret value is marked with ACSCurrent, and the previous version that was marked with ACSCurrent is marked with ACSPrevious. You can specify the VersionStage parameter to overwrite this default behavior.

  • This operation stores a new version of a secret value. You cannot use it to modify an existing version of a secret value. You must specify a version number when you store a new version. KMS processes requests based on the following rules:

    • If the version number does not exist in the secret, KMS creates a new version and stores the secret value.

    • If the version number already exists in the secret, KMS compares the secret value in the request with the stored value. If the values are the same, the request is ignored and a success message is returned. This makes the operation idempotent. If the values are different, the request is rejected.

This topic provides an example of how to store a new version of a secret value for the secret named secret001. The new version number (VersionId) is v3 and the secret value (SecretData) is importantdata.
