[ aws . lex-models ]



Creates a new version of a slot type based on the $LATEST version of the specified slot type. If the $LATEST version of this resource has not changed since the last version that you created, Amazon Lex doesn’t create a new version. It returns the last version that you created.


You can update only the $LATEST version of a slot type. You can’t update the numbered versions that you create with the CreateSlotTypeVersion operation.

When you create a version of a slot type, Amazon Lex sets the version to 1. Subsequent versions increment by 1. For more information, see versioning-intro .

This operation requires permissions for the lex:CreateSlotTypeVersion action.

--name (string)

The name of the slot type that you want to create a new version for. The name is case sensitive.

--checksum (string)

Checksum for the $LATEST version of the slot type that you want to publish. If you specify a checksum and the $LATEST version of the slot type has a different checksum, Amazon Lex returns a PreconditionFailedException exception and doesn’t publish the new version. If you don’t specify a checksum, Amazon Lex publishes the $LATEST version.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


name -> (string)

description -> (string)

A description of the slot type.

enumerationValues -> (list)

A list of EnumerationValue objects that defines the values that the slot type can take.


Each slot type can have a set of values. Each enumeration value represents a value the slot type can take.

For example, a pizza ordering bot could have a slot type that specifies the type of crust that the pizza should have. The slot type could include the values

  • thick

  • thin

  • stuffed

value -> (string)

The value of the slot type.

synonyms -> (list)

Additional values related to the slot type value.


lastUpdatedDate -> (timestamp)

The date that the slot type was updated. When you create a resource, the creation date and last update date are the same.

createdDate -> (timestamp)

The date that the slot type was created.

version -> (string)

The version assigned to the new slot type version.

checksum -> (string)

Checksum of the $LATEST version of the slot type.

valueSelectionStrategy -> (string)

The strategy that Amazon Lex uses to determine the value of the slot. For more information, see PutSlotType .

parentSlotTypeSignature -> (string)

The built-in slot type used a the parent of the slot type.

slotTypeConfigurations -> (list)

Configuration information that extends the parent built-in slot type.


Provides configuration information for a slot type.

regexConfiguration -> (structure)

A regular expression used to validate the value of a slot.

pattern -> (string)

A regular expression used to validate the value of a slot.

Use a standard regular expression. Amazon Lex supports the following characters in the regular expression:

  • A-Z, a-z

  • 0-9

  • Unicode characters (“u<Unicode>”)

Represent Unicode characters with four digits, for example “u0041” or “u005A”.
