Removes session information for a specified bot, alias, and user ID.

You can use this operation to restart a conversation with a bot. When you remove a session, the entire history of the session is removed so that you can start again.

If you specify a bot or alias ID that doesn't exist, you receive a BadRequestException.

If the locale doesn't exist in the bot, or if the locale hasn't been enables for the alias, you receive a BadRequestException.

Sends user input to Amazon Lex V2. Client applications use this API to send requests to Amazon Lex V2 at runtime. Amazon Lex V2 then interprets the user input using the machine learning model that it build for the bot.

In response, Amazon Lex V2 returns the next message to convey to the user and an optional response card to display.

If the optional post-fulfillment response is specified, the messages are returned as follows. For more information, see PostFulfillmentStatusSpecification.

• Success message - Returned if the Lambda function completes successfully and the intent state is fulfilled or ready fulfillment if the message is present.

• Failed message - The failed message is returned if the Lambda function throws an exception or if the Lambda function returns a failed intent state without a message.

• Timeout message - If you don't configure a timeout message and a timeout, and the Lambda function doesn't return within 30 seconds, the timeout message is returned. If you configure a timeout, the timeout message is returned when the period times out.
