key

The name of the filter.

The ParameterStringFilter object is used by the DescribeParameters and GetParametersByPath API operations. However, not all of the pattern values listed for Key can be used with both operations.

For DescribeParameters, all of the listed patterns are valid except Label.

For GetParametersByPath, the following patterns listed for Key aren't valid: tag, DataType, Name, Path, and Tier.

For examples of Amazon Web Services CLI commands demonstrating valid parameter filter constructions, see Searching for Systems Manager parameters in the Amazon Web Services Systems Manager User Guide.
