Paws::LexModels::PutSlotType - Arguments for method PutSlotType on Paws::LexModels


This class represents the parameters used for calling the method PutSlotType on the Amazon Lex Model Building Service service. Use the attributes of this class as arguments to method PutSlotType.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to PutSlotType.


    my $models.lex = Paws->service('LexModels');
    my $PutSlotTypeResponse = $models . lex->PutSlotType(
      Name              => 'MySlotTypeName',
      Checksum          => 'MyString',         # OPTIONAL
      CreateVersion     => 1,                  # OPTIONAL
      Description       => 'MyDescription',    # OPTIONAL
      EnumerationValues => [
          Value    => 'MyValue',               # min: 1, max: 140
          Synonyms => [
            'MyValue', ...                     # min: 1, max: 140
          ],                                   # OPTIONAL
      ],                                       # OPTIONAL
      ValueSelectionStrategy => 'ORIGINAL_VALUE',    # OPTIONAL

    # Results:
    my $Checksum               = $PutSlotTypeResponse->Checksum;
    my $CreateVersion          = $PutSlotTypeResponse->CreateVersion;
    my $CreatedDate            = $PutSlotTypeResponse->CreatedDate;
    my $Description            = $PutSlotTypeResponse->Description;

    my $Name                   = $PutSlotTypeResponse->Name;
    my $ValueSelectionStrategy = $PutSlotTypeResponse->ValueSelectionStrategy;
    my $Version                = $PutSlotTypeResponse->Version;

    # Returns a L<Paws::LexModels::PutSlotTypeResponse> object.

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see


Checksum => Str

Identifies a specific revision of the $LATEST version.

When you create a new slot type, leave the checksum field blank. If you specify a checksum you get a BadRequestException exception.

When you want to update a slot type, set the checksum field to the checksum of the most recent revision of the $LATEST version. If you don't specify the checksum field, or if the checksum does not match the $LATEST version, you get a PreconditionFailedException exception.

CreateVersion => Bool

Description => Str

A description of the slot type.

EnumerationValues => ArrayRef[Paws::LexModels::EnumerationValue]

A list of EnumerationValue objects that defines the values that the slot type can take. Each value can have a list of synonyms, which are additional values that help train the machine learning model about the values that it resolves for a slot.

When Amazon Lex resolves a slot value, it generates a resolution list that contains up to five possible values for the slot. If you are using a Lambda function, this resolution list is passed to the function. If you are not using a Lambda function you can choose to return the value that the user entered or the first value in the resolution list as the slot value. The valueSelectionStrategy field indicates the option to use.

REQUIRED Name => Str

The name of the slot type. The name is not case sensitive.

The name can't match a built-in slot type name, or a built-in slot type name with "AMAZON." removed. For example, because there is a built-in slot type called AMAZON.DATE, you can't create a custom slot type called DATE.

For a list of built-in slot types, see Slot Type Reference ( in the Alexa Skills Kit.

ValueSelectionStrategy => Str

Determines the slot resolution strategy that Amazon Lex uses to return slot type values. The field can be set to one of the following values:

  • ORIGINAL_VALUE - Returns the value entered by the user, if the user value is similar to the slot value.

  • TOP_RESOLUTION - If there is a resolution list for the slot, return the first value in the resolution list as the slot type value. If there is no resolution list, null is returned.

If you don't specify the valueSelectionStrategy, the default is ORIGINAL_VALUE.
