# Get a value from AWS Secrets Manager
<a name="get-secrets-manager-value"></a>

To use values from AWS Secrets Manager in your AWS CDK app, use the [https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_secretsmanager.Secret.html#static-fromwbrsecretwbrattributesscope-id-attrs](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_secretsmanager.Secret.html#static-fromwbrsecretwbrattributesscope-id-attrs) method. It represents a value that is retrieved from Secrets Manager and used at AWS CloudFormation deployment time. The following is an example:

**Example**  

```
import * as sm from "aws-cdk-lib/aws-secretsmanager";

export class SecretsManagerStack extends cdk.Stack {
  constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const secret = sm.Secret.fromSecretAttributes(this, "ImportedSecret", {
      secretCompleteArn:
        "arn:aws:secretsmanager:<region>:<account-id-number>:secret:<secret-name>-<random-6-characters>"
      // If the secret is encrypted using a KMS-hosted CMK, either import or reference that key:
      // encryptionKey: ...
      }
    );
  }
}
```

```
const sm = require("aws-cdk-lib/aws-secretsmanager");

class SecretsManagerStack extends cdk.Stack {
  constructor(scope, id, props) {
    super(scope, id, props);

    const secret = sm.Secret.fromSecretAttributes(this, "ImportedSecret", {
      secretCompleteArn:
        "arn:aws:secretsmanager:<region>:<account-id-number>:secret:<secret-name>-<random-6-characters>"
      // If the secret is encrypted using a KMS-hosted CMK, either import or reference that key:
      // encryptionKey: ...
    });
  }
}

module.exports = { SecretsManagerStack }
```

```
import aws_cdk.aws_secretsmanager as sm

class SecretsManagerStack(cdk.Stack):
    def __init__(self, scope: cdk.App, id: str, **kwargs):
      super().__init__(scope, name, **kwargs)

      secret = sm.Secret.from_secret_attributes(self, "ImportedSecret",
          secret_complete_arn="arn:aws:secretsmanager:<region>:<account-id-number>:secret:<secret-name>-<random-6-characters>",
          # If the secret is encrypted using a KMS-hosted CMK, either import or reference that key:
          # encryption_key=....
      )
```

```
import software.amazon.awscdk.services.secretsmanager.Secret;
import software.amazon.awscdk.services.secretsmanager.SecretAttributes;

public class SecretsManagerStack extends Stack {
    public SecretsManagerStack(App scope, String id) {
        this(scope, id, null);
    }

    public SecretsManagerStack(App scope, String id, StackProps props) {
        super(scope, id, props);

        Secret secret = (Secret)Secret.fromSecretAttributes(this, "ImportedSecret", SecretAttributes.builder()
            .secretCompleteArn("arn:aws:secretsmanager:<region>:<account-id-number>:secret:<secret-name>-<random-6-characters>")
             // If the secret is encrypted using a KMS-hosted CMK, either import or reference that key:
             // .encryptionKey(...)
             .build());
    }
}
```

```
using Amazon.CDK.AWS.SecretsManager;

public class SecretsManagerStack : Stack
{
    public SecretsManagerStack(App scope, string id, StackProps props) : base(scope, id, props) {

        var secret = Secret.FromSecretAttributes(this, "ImportedSecret", new SecretAttributes {
            SecretCompleteArn = "arn:aws:secretsmanager:<region>:<account-id-number>:secret:<secret-name>-<random-6-characters>"
            // If the secret is encrypted using a KMS-hosted CMK, either import or reference that key:
            // encryptionKey = ...,
        });
    }
}
```

**Tip**  
Use the AWS CLI [https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_secretsmanager.Secret.html](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_secretsmanager.Secret.html) CLI command to create a secret from the command line, such as when testing:  

```
aws secretsmanager create-secret --name ImportedSecret --secret-string mygroovybucket
```
The command returns an ARN that you can use with the preceding example.

Once you have created a `Secret` instance, you can get the secret’s value from the instance’s `secretValue` attribute. The value is represented by a [https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.SecretValue.html](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.SecretValue.html) instance, a special type of [Tokens and the AWS CDK](tokens.md). Because it’s a token, it has meaning only after resolution. Your CDK app does not need to access its actual value. Instead, the app can pass the `SecretValue` instance (or its string or numeric representation) to whatever CDK method needs the value.
