Use PutParameter with an Amazon SDK or CLI

Example 1: To change a parameter value

The following put-parameter example changes the value of the specified parameter.

aws ssm put-parameter \
    --name "MyStringParameter" \
    --type "String" \
    --value "Vici" \
    --overwrite

Output:

{
    "Version": 2,
    "Tier": "Standard"
}

For more information, see Create a Systems Manager parameter (Amazon CLI), 'Managing parameter tiers <https://docs.aws.amazon.com/systems-manager/latest/userguide/parameter-store-advanced-parameters.html>`__, and Working with parameter policies in the Amazon Systems Manager User Guide.

Example 2: To create an advanced parameter

The following put-parameter example creates an advanced parameter.

aws ssm put-parameter \
    --name "MyAdvancedParameter" \
    --description "This is an advanced parameter" \
    --value "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat [truncated]" \
    --type "String" \
    --tier Advanced

Output:

{
    "Version": 1,
    "Tier": "Advanced"
}

Example 3: To convert a standard parameter to an advanced parameter

The following put-parameter example converts a existing standard parameter into an advanced parameter.

aws ssm put-parameter \
    --name "MyConvertedParameter" \
    --value "abc123" \
    --type "String" \
    --tier Advanced \
    --overwrite

Output:

{
    "Version": 2,
    "Tier": "Advanced"
}

For more information, see Create a Systems Manager parameter (Amazon CLI), 'Managing parameter tiers <https://docs.aws.amazon.com/systems-manager/latest/userguide/parameter-store-advanced-parameters.html>`__, and Working with parameter policies in the Amazon Systems Manager User Guide.

Example 4: To create a parameter with a policy attached

The following put-parameter example creates an advanced parameter with a parameter policy attached.

aws ssm put-parameter \
    --name "/Finance/Payroll/q2accesskey" \
    --value "P@sSwW)rd" \
    --type "SecureString" \
    --tier Advanced \
    --policies "[{\"Type\":\"Expiration\",\"Version\":\"1.0\",\"Attributes\":{\"Timestamp\":\"2020-06-30T00:00:00.000Z\"}},{\"Type\":\"ExpirationNotification\",\"Version\":\"1.0\",\"Attributes\":{\"Before\":\"5\",\"Unit\":\"Days\"}},{\"Type\":\"NoChangeNotification\",\"Version\":\"1.0\",\"Attributes\":{\"After\":\"60\",\"Unit\":\"Days\"}}]"

Output:

{
    "Version": 1,
    "Tier": "Advanced"
}

For more information, see Create a Systems Manager parameter (Amazon CLI), 'Managing parameter tiers <https://docs.aws.amazon.com/systems-manager/latest/userguide/parameter-store-advanced-parameters.html>`__, and Working with parameter policies in the Amazon Systems Manager User Guide.

Example 5: To add a policy to an existing parameter

The following put-parameter example attaches a policy to an existing advanced parameter.

aws ssm put-parameter \
    --name "/Finance/Payroll/q2accesskey" \
    --value "N3wP@sSwW)rd" \
    --type "SecureString" \
    --tier Advanced \
    --policies "[{\"Type\":\"Expiration\",\"Version\":\"1.0\",\"Attributes\":{\"Timestamp\":\"2020-06-30T00:00:00.000Z\"}},{\"Type\":\"ExpirationNotification\",\"Version\":\"1.0\",\"Attributes\":{\"Before\":\"5\",\"Unit\":\"Days\"}},{\"Type\":\"NoChangeNotification\",\"Version\":\"1.0\",\"Attributes\":{\"After\":\"60\",\"Unit\":\"Days\"}}]"
    --overwrite

Output:

{
    "Version": 2,
    "Tier": "Advanced"
}

Example 1: This example creates a parameter. There is no output if the command succeeds.

Write-SSMParameter -Name "Welcome" -Type "String" -Value "helloWorld"

Example 2: This example changes a parameter. There is no output if the command succeeds.

Write-SSMParameter -Name "Welcome" -Type "String" -Value "Good day, Sunshine!" -Overwrite $true
