create_intent_version

LexModelBuildingService.Client.create_intent_version(**kwargs)

Creates a new version of an intent based on the $LATEST version of the intent. If the $LATEST version of this intent hasn’t changed since you last updated it, Amazon Lex doesn’t create a new version. It returns the last version you created.

Note

You can update only the $LATEST version of the intent. You can’t update the numbered versions that you create with the CreateIntentVersion operation.

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

This operation requires permissions to perform the lex:CreateIntentVersion action.

Request Syntax

response = client.create_intent_version(
    name='string',
    checksum='string'
)

Parameters:

• name (string) –

  [REQUIRED]

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

• checksum (string) – Checksum of the $LATEST version of the intent that should be used to create the new version. If you specify a checksum and the $LATEST version of the intent has a different checksum, Amazon Lex returns a PreconditionFailedException exception and doesn’t publish a new version. If you don’t specify a checksum, Amazon Lex publishes the $LATEST version.

Return type:

dict

Response Structure

• (dict) –

  • name (string) –

    The name of the intent.

  • description (string) –

    A description of the intent.

    • (dict) –

      Identifies the version of a specific slot.

      • name (string) –

        The name of the slot.

      • description (string) –

        A description of the slot.

      • slotConstraint (string) –

        Specifies whether the slot is required or optional.

      • slotType (string) –

        The type of the slot, either a custom slot type that you defined or one of the built-in slot types.

      • slotTypeVersion (string) –

        The version of the slot type.

      • valueElicitationPrompt (dict) –

        The prompt that Amazon Lex uses to elicit the slot value from the user.

        • messages (list) –

          An array of objects, each of which provides a message string and its type. You can specify the message string in plain text or in Speech Synthesis Markup Language (SSML).

          • (dict) –

            The message object that provides the message text and its type.

            • contentType (string) –

              The content type of the message string.

            • content (string) –

              The text of the message.

            • groupNumber (integer) –

              Identifies the message group that the message belongs to. When a group is assigned to a message, Amazon Lex returns one message from each group in the response.

        • maxAttempts (integer) –

          The number of times to prompt the user for information.

        • responseCard (string) –

          A response card. Amazon Lex uses this prompt at runtime, in the PostText API response. It substitutes session attributes and slot values for placeholders in the response card. For more information, see ex-resp-card.

      • priority (integer) –

        Directs Amazon Lex the order in which to elicit this slot value from the user. For example, if the intent has two slots with priorities 1 and 2, AWS Amazon Lex first elicits a value for the slot with priority 1.

        If multiple slots share the same priority, the order in which Amazon Lex elicits values is arbitrary.

      • sampleUtterances (list) –

        If you know a specific pattern with which users might respond to an Amazon Lex request for a slot value, you can provide those utterances to improve accuracy. This is optional. In most cases, Amazon Lex is capable of understanding user utterances.

        • (string) –

      • responseCard (string) –

        A set of possible responses for the slot type used by text-based clients. A user chooses an option from the response card, instead of using text to reply.

      • obfuscationSetting (string) –

        Determines whether a slot is obfuscated in conversation logs and stored utterances. When you obfuscate a slot, the value is replaced by the slot name in curly braces ({}). For example, if the slot name is “full_name”, obfuscated values are replaced with “{full_name}”. For more information, see Slot Obfuscation.

      • defaultValueSpec (dict) –

        A list of default values for the slot. Default values are used when Amazon Lex hasn’t determined a value for a slot. You can specify default values from context variables, session attributes, and defined values.

        • defaultValueList (list) –

          The default values for a slot. You can specify more than one default. For example, you can specify a default value to use from a matching context variable, a session attribute, or a fixed value.

          The default value chosen is selected based on the order that you specify them in the list. For example, if you specify a context variable and a fixed value in that order, Amazon Lex uses the context variable if it is available, else it uses the fixed value.

          • (dict) –

            A default value for a slot.

            • defaultValue (string) –

              The default value for the slot. You can specify one of the following:

              • #context-name.slot-name - The slot value “slot-name” in the context “context-name.”

              • {attribute} - The slot value of the session attribute “attribute.”
