Creates a new secret. A secret can be a password, a set of credentials such as a user name and password, an OAuth token, or other secret information that you store in an encrypted form in Secrets Manager. The secret also includes the connection information to access a database or other service, which Secrets Manager doesn't encrypt. A secret in Secrets Manager consists of both the protected secret data and the important information needed to manage the secret.

For secrets that use managed rotation, you need to create the secret through the managing service. For more information, see Secrets Manager secrets managed by other Amazon Web Services services.

For information about creating a secret in the console, see Create a secret.

To create a secret, you can provide the secret value to be encrypted in either the SecretString parameter or the SecretBinary parameter, but not both. If you include SecretString or SecretBinary then Secrets Manager creates an initial secret version and automatically attaches the staging label AWSCURRENT to it.

For database credentials you want to rotate, for Secrets Manager to be able to rotate the secret, you must make sure the JSON you store in the SecretString matches the JSON structure of a database secret.

If you don't specify an KMS encryption key, Secrets Manager uses the Amazon Web Services managed key aws/secretsmanager. If this key doesn't already exist in your account, then Secrets Manager creates it for you automatically. All users and roles in the Amazon Web Services account automatically have access to use aws/secretsmanager. Creating aws/secretsmanager can result in a one-time significant delay in returning the result.

If the secret is in a different Amazon Web Services account from the credentials calling the API, then you can't use aws/secretsmanager to encrypt the secret, and you must create and use a customer managed KMS key.

Secrets Manager generates a CloudTrail log entry when you call this action. Do not include sensitive information in request parameters except SecretBinary or SecretString because it might be logged. For more information, see Logging Secrets Manager events with CloudTrail.

Required permissions: secretsmanager:CreateSecret. If you include tags in the secret, you also need secretsmanager:TagResource. For more information, see IAM policy actions for Secrets Manager and Authentication and access control in Secrets Manager.

To encrypt the secret with a KMS key other than aws/secretsmanager, you need kms:GenerateDataKey and kms:Decrypt permission to the key.

Headers

X-Amz-Target'secretsmanager.CreateSecret' required

Request body

Namestring required
<p>The name of the new secret.</p> <p>The secret name can contain ASCII letters, numbers, and the following characters: /_+=.@-</p> <p>Do not end your secret name with a hyphen followed by six characters. If you do so, you risk confusion and unexpected results when searching for a secret by partial ARN. Secrets Manager automatically adds a hyphen and six random characters after the secret name at the end of the ARN.</p>
ClientRequestTokenstring
<p>If you include <code>SecretString</code> or <code>SecretBinary</code>, then Secrets Manager creates an initial version for the secret, and this parameter specifies the unique identifier for the new version. </p> <note> <p>If you use the Amazon Web Services CLI or one of the Amazon Web Services SDKs to call this operation, then you can leave this parameter empty. The CLI or SDK generates a random UUID for you and includes it as the value for this parameter in the request. If you don't use the SDK and instead generate a raw HTTP request to the Secrets Manager service endpoint, then you must generate a <code>ClientRequestToken</code> yourself for the new version and include the value in the request.</p> </note> <p>This value helps ensure idempotency. Secrets Manager uses this value to prevent the accidental creation of duplicate versions if there are failures and retries during a rotation. We recommend that you generate a <a href="https://wikipedia.org/wiki/Universally_unique_identifier">UUID-type</a> value to ensure uniqueness of your versions within the specified secret. </p> <ul> <li> <p>If the <code>ClientRequestToken</code> value isn't already associated with a version of the secret then a new version of the secret is created. </p> </li> <li> <p>If a version with this value already exists and the version <code>SecretString</code> and <code>SecretBinary</code> values are the same as those in the request, then the request is ignored.</p> </li> <li> <p>If a version with this value already exists and that version's <code>SecretString</code> and <code>SecretBinary</code> values are different from those in the request, then the request fails because you cannot modify an existing version. Instead, use <a>PutSecretValue</a> to create a new version.</p> </li> </ul> <p>This value becomes the <code>VersionId</code> of the new version.</p>
Descriptionstring

The description of the secret.

KmsKeyIdstring
<p>The ARN, key ID, or alias of the KMS key that Secrets Manager uses to encrypt the secret value in the secret. An alias is always prefixed by <code>alias/</code>, for example <code>alias/aws/secretsmanager</code>. For more information, see <a href="https://docs.aws.amazon.com/kms/latest/developerguide/alias-about.html">About aliases</a>.</p> <p>To use a KMS key in a different account, use the key ARN or the alias ARN.</p> <p>If you don't specify this value, then Secrets Manager uses the key <code>aws/secretsmanager</code>. If that key doesn't yet exist, then Secrets Manager creates it for you automatically the first time it encrypts the secret value.</p> <p>If the secret is in a different Amazon Web Services account from the credentials calling the API, then you can't use <code>aws/secretsmanager</code> to encrypt the secret, and you must create and use a customer managed KMS key. </p>
SecretBinarystring password
<p>The binary data to encrypt and store in the new version of the secret. We recommend that you store your binary data in a file and then pass the contents of the file as a parameter.</p> <p>Either <code>SecretString</code> or <code>SecretBinary</code> must have a value, but not both.</p> <p>This parameter is not available in the Secrets Manager console.</p>
SecretStringstring password
<p>The text data to encrypt and store in this new version of the secret. We recommend you use a JSON structure of key/value pairs for your secret value.</p> <p>Either <code>SecretString</code> or <code>SecretBinary</code> must have a value, but not both.</p> <p>If you create a secret by using the Secrets Manager console then Secrets Manager puts the protected secret text in only the <code>SecretString</code> parameter. The Secrets Manager console stores the information as a JSON structure of key/value pairs that a Lambda rotation function can parse.</p>
ForceOverwriteReplicaSecretboolean

Specifies whether to overwrite a secret with the same name in the destination Region. By default, secrets aren't overwritten.

Response

Success

ARNstring

The ARN of the new secret. The ARN includes the name of the secret followed by six random characters. This ensures that if you create a new secret with the same name as a deleted secret, then users with access to the old secret don't get access to the new secret because the ARNs are different.

Namestring

The name of the new secret.

VersionIdstring

The unique identifier associated with the version of the new secret.
