Step 1: Create an Amazon Lex Bot - Amazon Lex V1

If you are using Amazon Lex V2, refer to the Amazon Lex V2 guide instead.

 

If you are using Amazon Lex V1, we recommend upgrading your bots to Amazon Lex V2. We are no longer adding new features to V1 and strongly recommend using V2 for all new bots.

Step 1: Create an Amazon Lex Bot

In this section, you create an Amazon Lex bot using the ScheduleAppointment blueprint, which is provided in the Amazon Lex console.

  1. Sign in to the AWS Management Console and open the Amazon Lex console at https://console.aws.amazon.com/lex/.

  2. On the Bots page, choose Create.

  3. On the Create your Lex bot page, do the following:

    • Choose the ScheduleAppointment blueprint.

    • Leave the default bot name (ScheduleAppointment).

  4. Choose Create.

    This step saves and builds the bot. The console sends the following requests to Amazon Lex during the build process:

    • Create a new version of the slot types (from the $LATEST version). For information about slot types defined in this bot blueprint, see Overview of the Bot Blueprint (ScheduleAppointment).

    • Create a version of the MakeAppointment intent (from the $LATEST version). In some cases, the console sends a request for the update API operation before creating a new version.

    • Update the $LATEST version of the bot.

      At this time, Amazon Lex builds a machine learning model for the bot. When you test the bot in the console, the console uses the runtime API to send user input back to Amazon Lex. Amazon Lex then uses the machine learning model to interpret the user input.

  5. The console shows the ScheduleAppointment bot. On the Editor tab, review the preconfigured intent (MakeAppointment) details.

  6. Test the bot in the test window. Use the following screen shot to engage in a test conversation with your bot:

    Conversation with an agent, in which the agent asks the type of appointment, date, and time for an appointment and then confirms the appointment details.

    Note the following:

    • From the initial user input ("Book an appointment"), the bot infers the intent (MakeAppointment).

    • The bot then uses the configured prompts to get slot data from the user.

    • The bot blueprint has the MakeAppointment intent configured with the following confirmation prompt:

      {Time} is available, should I go ahead and book your appointment?

      After the user provides all of the slot data, Amazon Lex returns a response to the client with a confirmation prompt as the message. The client displays the message for the user:

      16:00 is available, should I go ahead and book your appointment?

    Notice that the bot accepts any appointment date and time values because you don't have any code to initialize or validate the user data. In the next section, you add a Lambda function to do this.
