name

The fully qualified name of the parameter that you want to create or update.

You can't enter the Amazon Resource Name (ARN) for a parameter, only the parameter name itself.

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

• Parameter names can't contain spaces. The service removes any spaces specified for the beginning or end of a parameter name. If the specified name for a parameter contains spaces between characters, the request fails with a ValidationException error.

• 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.

The reported maximum length of 2048 characters for a parameter name includes 1037 characters that are reserved for internal use by Systems Manager. The maximum length for a parameter name that you specify is 1011 characters.

This count of 1011 characters includes the characters in the ARN that precede the name you specify. This ARN length will vary depending on your partition and Region. For example, the following 45 characters count toward the 1011 character maximum for a parameter created in the US East (Ohio) Region: arn:aws:ssm:us-east-2:111122223333:parameter/.
