AWS Secrets Manager API Reference
AWS Secrets Manager API Reference Guide (API Version 2017-10-17)

PutSecretValue

Stores a new encrypted secret value in the specified secret. To do this, the operation creates a new version and attaches it to the secret. The version can contain a new SecretString value or a new SecretBinary value. You can also specify the staging labels that are initially attached to the new version.

Note

The Secrets Manager console uses only the SecretString field. To add binary data to a secret with the SecretBinary field you must use the AWS CLI or one of the AWS SDKs.

  • If this operation creates the first version for the secret then Secrets Manager automatically attaches the staging label AWSCURRENT to the new version.

  • If another version of this secret already exists, then this operation does not automatically move any staging labels other than those that you explicitly specify in the VersionStages parameter.

  • If this operation moves the staging label AWSCURRENT from another version to this version (because you included it in the StagingLabels parameter) then Secrets Manager also automatically moves the staging label AWSPREVIOUS to the version that AWSCURRENT was removed from.

  • This operation is idempotent. If a version with a VersionId with the same value as the ClientRequestToken parameter already exists and you specify the same secret data, the operation succeeds but does nothing. However, if the secret data is different, then the operation fails because you cannot modify an existing version; you can only create new ones.

Note

  • If you call an operation that needs to encrypt or decrypt the SecretString or SecretBinary for a secret in the same account as the calling user and that secret doesn't specify a AWS KMS encryption key, Secrets Manager uses the account's default AWS managed customer master key (CMK) with the alias 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 same AWS account automatically have access to use the default CMK. Note that if an Secrets Manager API call results in AWS having to create the account's AWS-managed CMK, it can result in a one-time significant delay in returning the result.

  • If the secret is in a different AWS account from the credentials calling an API that requires encryption or decryption of the secret value then you must create and use a custom AWS KMS CMK because you can't access the default CMK for the account using credentials from a different AWS account. Store the ARN of the CMK in the secret when you create the secret or when you update it by including it in the KMSKeyId. If you call an API that must encrypt or decrypt SecretString or SecretBinary using credentials from a different account then the AWS KMS key policy must grant cross-account access to that other account's user or role for both the kms:GenerateDataKey and kms:Decrypt operations.

Minimum permissions

To run this command, you must have the following permissions:

  • secretsmanager:PutSecretValue

  • kms:GenerateDataKey - needed only if you use a customer-managed AWS KMS key to encrypt the secret. You do not need this permission to use the account's default AWS managed CMK for Secrets Manager.

Request Syntax

{ "ClientRequestToken": "string", "SecretBinary": blob, "SecretId": "string", "SecretString": "string", "VersionStages": [ "string" ] }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

ClientRequestToken

(Optional) Specifies a unique identifier for the new version of the secret.

Note

If you use the AWS CLI or one of the AWS SDK to call this operation, then you can leave this parameter empty. The CLI or SDK generates a random UUID for you and includes that 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 ClientRequestToken yourself for new versions and include that value in the request.

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 the Lambda rotation function's processing. We recommend that you generate a UUID-type value to ensure uniqueness within the specified secret.

  • If the ClientRequestToken value isn't already associated with a version of the secret then a new version of the secret is created.

  • If a version with this value already exists and that version's SecretString or SecretBinary values are the same as those in the request then the request is ignored (the operation is idempotent).

  • If a version with this value already exists and that version's SecretString and SecretBinary values are different from those in the request then the request fails because you cannot modify an existing secret version. You can only create new versions to store new secret values.

This value becomes the VersionId of the new version.

Type: String

Length Constraints: Minimum length of 32. Maximum length of 64.

Required: No

SecretBinary

(Optional) Specifies binary data that you want to encrypt and store in the new version of the secret. To use this parameter in the command-line tools, we recommend that you store your binary data in a file and then use the appropriate technique for your tool to pass the contents of the file as a parameter. Either SecretBinary or SecretString must have a value, but not both. They cannot both be empty.

This parameter is not accessible if the secret using the Secrets Manager console.

Type: Base64-encoded binary data object

Length Constraints: Minimum length of 0. Maximum length of 4096.

Required: No

SecretId

Specifies the secret to which you want to add a new version. You can specify either the Amazon Resource Name (ARN) or the friendly name of the secret. The secret must already exist.

Note

If you specify an ARN, we generally recommend that you specify a complete ARN. You can specify a partial ARN too—for example, if you don’t include the final hyphen and six random characters that Secrets Manager adds at the end of the ARN when you created the secret. A partial ARN match can work as long as it uniquely matches only one secret. However, if your secret has a name that ends in a hyphen followed by six characters (before Secrets Manager adds the hyphen and six characters to the ARN) and you try to use that as a partial ARN, then those characters cause Secrets Manager to assume that you’re specifying a complete ARN. This confusion can cause unexpected results. To avoid this situation, we recommend that you don’t create secret names that end with a hyphen followed by six characters.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Required: Yes

SecretString

(Optional) Specifies text data that you want to encrypt and store in this new version of the secret. Either SecretString or SecretBinary must have a value, but not both. They cannot both be empty.

If you create this secret by using the Secrets Manager console then Secrets Manager puts the protected secret text in only the SecretString parameter. The Secrets Manager console stores the information as a JSON structure of key/value pairs that the default Lambda rotation function knows how to parse.

For storing multiple values, we recommend that you use a JSON text string argument and specify key/value pairs. For information on how to format a JSON parameter for the various command line tool environments, see Using JSON for Parameters in the AWS CLI User Guide.

For example:

[{"username":"bob"},{"password":"abc123xyz456"}]

If your command-line tool or SDK requires quotation marks around the parameter, you should use single quotes to avoid confusion with the double quotes required in the JSON text.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 4096.

Required: No

VersionStages

(Optional) Specifies a list of staging labels that are attached to this version of the secret. These staging labels are used to track the versions through the rotation process by the Lambda rotation function.

A staging label must be unique to a single version of the secret. If you specify a staging label that's already associated with a different version of the same secret then that staging label is automatically removed from the other version and attached to this version.

If you do not specify a value for VersionStages then Secrets Manager automatically moves the staging label AWSCURRENT to this new version.

Type: Array of strings

Array Members: Minimum number of 1 item. Maximum number of 20 items.

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: No

Response Syntax

{ "ARN": "string", "Name": "string", "VersionId": "string", "VersionStages": [ "string" ] }
