      Request

      Header Params
      X-Amz-Target
      string 
      required
      Body Params application/json
      Name
      string 
      required
      The fully qualified name of the parameter that you want to add to the system. The fully qualified name includes the complete hierarchy of the parameter path and name. For parameters in a hierarchy, you must include a leading forward slash character (/) when you create or reference a parameter. For example: /Dev/DBServer/MySQL/db-string13
      Naming Constraints:
      • Parameter names are case sensitive.
      • A parameter name must be unique within an Amazon Web Services Region
      • A parameter name can't be prefixed with "aws" or "ssm" (case-insensitive).
      • Parameter names can include only the following symbols and letters: a-zA-Z0-9_.-
        In addition, the slash character ( / ) is used to delineate hierarchies in parameter names. For example: /Dev/Production/East/Project-ABC/MyParameter
      • A parameter name can't include spaces.
      • Parameter hierarchies are limited to a maximum depth of fifteen levels.
      For additional information about valid values for parameter names, see Creating Systems Manager parameters in the Amazon Web Services Systems Manager User Guide.
      >= 1 characters<= 2048 characters
      Description
      string 
      optional
      Information about the parameter that you want to add to the system. Optional but recommended.
      >= 0 characters<= 1024 characters
      Value
      string <password>
      required
      The parameter value that you want to add to the system. Standard parameters have a value limit of 4 KB. Advanced parameters have a value limit of 8 KB.
      Type
      enum<string> 
      optional
      The type of parameter that you want to add to the system.
      Items in a StringList must be separated by a comma (,). You can't use other punctuation or special character to escape items in the list. If you have a parameter value that requires a comma, then use the String data type.
      Allowed values:
      StringStringListSecureString
      KeyId
      string 
      optional
      The Key Management Service (KMS) ID that you want to use to encrypt a parameter. Use a custom key for better security. Required for parameters that use the SecureString data type.
      If you don't specify a key ID, the system uses the default key associated with your Amazon Web Services account which is not as secure as using a custom key.
      • To use a custom KMS key, choose the SecureString data type with the Key ID parameter.
      >= 1 characters<= 256 characters
      Match pattern:
      ^([a-zA-Z0-9:/_-]+)$
      Overwrite
      boolean 
      optional
      Overwrite an existing parameter. The default value is false.
      AllowedPattern
      string 
      optional
      A regular expression used to validate the parameter value. For example, for String types with values restricted to numbers, you can specify the following: AllowedPattern=^\d+$
      >= 0 characters<= 1024 characters
      Tags
      array[object (Tag) {2}] 
      optional
      Optional metadata that you assign to a resource. Tags enable you to categorize a resource in different ways, such as by purpose, owner, or environment. For example, you might want to tag a Systems Manager parameter to identify the type of resource to which it applies, the environment, or the type of configuration data referenced by the parameter. In this case, you could specify the following key-value pairs:
      • Key=Resource,Value=S3bucket
      • Key=OS,Value=Windows
      • Key=ParameterType,Value=LicenseKey
      <= 1000 items
      Key
      string 
      required
      The name of the tag.
      >= 1 characters<= 128 characters
      Match pattern:
      ^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$
      Value
      string 
      required
      The value of the tag.
      >= 0 characters<= 256 characters
      Match pattern:
      ^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$
      Tier
      enum<string> 
      optional
      The parameter tier to assign to a parameter.
      Parameter Store offers a standard tier and an advanced tier for parameters. Standard parameters have a content size limit of 4 KB and can't be configured to use parameter policies. You can create a maximum of 10,000 standard parameters for each Region in an Amazon Web Services account. Standard parameters are offered at no additional cost.
      Advanced parameters have a content size limit of 8 KB and can be configured to use parameter policies. You can create a maximum of 100,000 advanced parameters for each Region in an Amazon Web Services account. Advanced parameters incur a charge. For more information, see Standard and advanced parameter tiers in the Amazon Web Services Systems Manager User Guide.
      You can change a standard parameter to an advanced parameter any time. But you can't revert an advanced parameter to a standard parameter. Reverting an advanced parameter to a standard parameter would result in data loss because the system would truncate the size of the parameter from 8 KB to 4 KB. Reverting would also remove any policies attached to the parameter. Lastly, advanced parameters use a different form of encryption than standard parameters.
      If you no longer need an advanced parameter, or if you no longer want to incur charges for an advanced parameter, you must delete it and recreate it as a new standard parameter.
      Using the Default Tier Configuration
      In PutParameter requests, you can specify the tier to create the parameter in. Whenever you specify a tier in the request, Parameter Store creates or updates the parameter according to that request. However, if you don't specify a tier in a request, Parameter Store assigns the tier based on the current Parameter Store default tier configuration.
      The default tier when you begin using Parameter Store is the standard-parameter tier. If you use the advanced-parameter tier, you can specify one of the following as the default:
      • Advanced: With this option, Parameter Store evaluates all requests as advanced parameters.
      • Intelligent-Tiering: With this option, Parameter Store evaluates each request to determine if the parameter is standard or advanced.
        If the request doesn't include any options that require an advanced parameter, the parameter is created in the standard-parameter tier. If one or more options requiring an advanced parameter are included in the request, Parameter Store create a parameter in the advanced-parameter tier.
        This approach helps control your parameter-related costs by always creating standard parameters unless an advanced parameter is necessary.
      Options that require an advanced parameter include the following:
      • The content size of the parameter is more than 4 KB.
      • The parameter uses a parameter policy.
      • More than 10,000 parameters already exist in your Amazon Web Services account in the current Amazon Web Services Region.
      For more information about configuring the default tier option, see Specifying a default parameter tier in the Amazon Web Services Systems Manager User Guide.
      Allowed values:
      StandardAdvancedIntelligent-Tiering
      Policies
      string 
      optional
      One or more policies to apply to a parameter. This operation takes a JSON array. Parameter Store, a capability of Amazon Web Services Systems Manager supports the following policy types:
      Expiration: This policy deletes the parameter after it expires. When you create the policy, you specify the expiration date. You can update the expiration date and time by updating the policy. Updating the parameter doesn't affect the expiration date and time. When the expiration time is reached, Parameter Store deletes the parameter.
      ExpirationNotification: This policy initiates an event in Amazon CloudWatch Events that notifies you about the expiration. By using this policy, you can receive notification before or after the expiration time is reached, in units of days or hours.
      NoChangeNotification: This policy initiates a CloudWatch Events event if a parameter hasn't been modified for a specified period of time. This policy type is useful when, for example, a secret needs to be changed within a period of time, but it hasn't been changed.
      All existing policies are preserved until you send new policies or an empty policy. For more information about parameter policies, see Assigning parameter policies.
      >= 1 characters<= 4096 characters
      DataType
      string 
      optional
      The data type for a String parameter. Supported data types include plain text and Amazon Machine Image (AMI) IDs.
      The following data type values are supported.
      • text
      • aws:ec2:image
      • aws:ssm:integration
      When you create a String parameter and specify aws:ec2:image, Amazon Web Services Systems Manager validates the parameter value is in the required format, such as ami-12345abcdeEXAMPLE, and that the specified AMI is available in your Amazon Web Services account.
      >= 0 characters<= 128 characters

      🟢200Success
      application/json
      Body
      Version
      integer 
      optional
      The new version number of a parameter. If you edit a parameter value, Parameter Store automatically creates a new version and assigns this new version a unique ID. You can reference a parameter version ID in API operations or in Systems Manager documents (SSM documents). By default, if you don't specify a specific version, the system returns the latest parameter value when a parameter is called.
      Tier
      enum<string> 
      optional
      The tier assigned to the parameter.
