# Use `GetParameter` with an AWS SDK or CLI
<a name="ssm_example_ssm_GetParameter_section"></a>

The following code examples show how to use `GetParameter`.

------
#### [ CLI ]

**AWS CLI**  
**Example 1: To display the value of a parameter**  
The following `get-parameter` example lists the value for the specified single parameter.  

```
aws ssm get-parameter \
    --name "MyStringParameter"
```
Output:  

```
{
    "Parameter": {
        "Name": "MyStringParameter",
        "Type": "String",
        "Value": "Veni",
        "Version": 1,
        "LastModifiedDate": 1530018761.888,
        "ARN": "arn:aws:ssm:us-east-2:111222333444:parameter/MyStringParameter"
        "DataType": "text"
    }
}
```
For more information, see [Working with Parameter Store](https://docs.aws.amazon.com/systems-manager/latest/userguide/parameter-store-working-with.html) in the *AWS Systems Manager User Guide*.  
**Example 2: To decrypt the value of a SecureString parameter**  
The following `get-parameter` example decrypts the value of the specified `SecureString` parameter.  

```
aws ssm get-parameter \
    --name "MySecureStringParameter" \
    --with-decryption
```
Output:  

```
{
    "Parameter": {
        "Name": "MySecureStringParameter",
        "Type": "SecureString",
        "Value": "16679b88-310b-4895-a943-e0764EXAMPLE",
        "Version": 2,
        "LastModifiedDate": 1582155479.205,
        "ARN": "arn:aws:ssm:us-east-2:111222333444:parameter/MySecureStringParameter"
        "DataType": "text"
    }
}
```

**Example 3: To display the value of a parameter using labels**  
The following `get-parameter` example lists the value for the specified single parameter with a specified label.  

```
aws ssm get-parameter \
    --name "MyParameter:label"
```
Output:  

```
{
    "Parameter": {
        "Name": "MyParameter",
        "Type": "String",
        "Value": "parameter version 2",
        "Version": 2,
        "Selector": ":label",
        "LastModifiedDate": "2021-07-12T09:49:15.865000-07:00",
        "ARN": "arn:aws:ssm:us-west-2:786973925828:parameter/MyParameter",
        "DataType": "text"
    }
}
```
For more information, see [Working with parameter labels](https://docs.aws.amazon.com/systems-manager/latest/userguide/sysman-paramstore-labels.html) in the *AWS Systems Manager User Guide*.  
**Example 4: To display the value of a parameter using versions**  
The following `get-parameter` example lists the value for the specified single parameter version.  

```
aws ssm get-parameter \
    --name "MyParameter:2"
```
Output:  

```
{
    "Parameter": {
        "Name": "MyParameter",
        "Type": "String",
        "Value": "parameter version 2",
        "Version": 2,
        "Selector": ":2",
        "LastModifiedDate": "2021-07-12T09:49:15.865000-07:00",
        "ARN": "arn:aws:ssm:us-west-2:786973925828:parameter/MyParameter",
        "DataType": "text"
    }
}
```

```
    pub async fn list_path(&self, path: &str) -> Result<Vec<Parameter>, EC2Error> {
        let maybe_params: Vec<Result<Parameter, _>> = TryFlatMap::new(
            self.inner
                .get_parameters_by_path()
                .path(path)
                .into_paginator()
                .send(),
        )
        .flat_map(|item| item.parameters.unwrap_or_default())
        .collect()
        .await;
        // Fail on the first error
        let params = maybe_params
            .into_iter()
            .collect::<Result<Vec<Parameter>, _>>()?;
        Ok(params)
    }
