// Retrieves the contents of the encrypted fields SecretString or SecretBinary for
// up to 20 secrets. To retrieve a single secret, call GetSecretValue . To choose
// which secrets to retrieve, you can specify a list of secrets by name or ARN, or
// you can use filters. If Secrets Manager encounters errors such as
// AccessDeniedException while attempting to retrieve any of the secrets, you can
// see the errors in Errors in the response. Secrets Manager generates CloudTrail
// GetSecretValue log entries for each secret you request when you call this
// action. Do not include sensitive information in request parameters because it
// might be logged. For more information, see Logging Secrets Manager events with
// CloudTrail (https://docs.aws.amazon.com/secretsmanager/latest/userguide/retrieve-ct-entries.html)
// . Required permissions: secretsmanager:BatchGetSecretValue , and you must have
// secretsmanager:GetSecretValue for each secret. If you use filters, you must also
// have secretsmanager:ListSecrets . If the secrets are encrypted using
// customer-managed keys instead of the Amazon Web Services managed key
// aws/secretsmanager , then you also need kms:Decrypt permissions for the keys.
// For more information, see IAM policy actions for Secrets Manager (https://docs.aws.amazon.com/secretsmanager/latest/userguide/reference_iam-permissions.html#reference_iam-permissions_actions)
