Parameters:

• botId (string) –

  [REQUIRED]

  The identifier of the bot that contains the slot.

• botVersion (string) –

  [REQUIRED]

  The version of the bot that contains the slot.

• localeId (string) –

  [REQUIRED]

  The identifier of the language and locale of the slots to list. The string must match one of the supported locales. For more information, see Supported languages.

• intentId (string) –

  [REQUIRED]

  The unique identifier of the intent that contains the slot.

• sortBy (dict) –

  Determines the sort order for the response from the ListSlots operation. You can choose to sort by the slot name or last updated date in either ascending or descending order.

  • attribute (string) – [REQUIRED]

    The attribute to use to sort the list.

  • order (string) – [REQUIRED]

    The order to sort the list. You can choose ascending or descending.

• filters (list) –

  Provides the specification of a filter used to limit the slots in the response to only those that match the filter specification. You can only specify one filter and only one string to filter on.

  • (dict) –

    Filters the response from the ListSlots operation.

    • name (string) – [REQUIRED]

      The name of the field to use for filtering.

      The value to use to filter the response.

      • (string) –

    • operator (string) – [REQUIRED]

      The operator to use for the filter. Specify EQ when the ListSlots operation should return only aliases that equal the specified value. Specify CO when the ListSlots operation should return aliases that contain the specified value.

• maxResults (integer) – The maximum number of slots to return in each page of results. If there are fewer results than the max page size, only the actual number of results are returned.

• nextToken (string) – If the response from the ListSlots operation contains more results than specified in the maxResults parameter, a token is returned in the response. Use that token in the nextToken parameter to return the next page of results.
