The Amazon Lex V2 bot that you want the flow to call.

The specific version of the Lex V2 bot you want to use. This version is the alias you create in the AWS console that points to a specific version of a bot.

Note: Depending on your bot configuration, if the bot supports multiple languages, then the same alias name may appear more than once. You can select the alias and language combination.

The initial intent that you want the flow to use. The options that are available here reflect the logic configured in the Lex V2 bot. 

Make sure that this intent name corresponds to a welcome intent; it should not be the actual intent that you want to collect. If you select such an intent, Lex V2 collects data and then expects you to transition to a new intent. If you then do not transition to another intent, the fallback intent is processed and the flow does not retrieve the slot values for the initial intent.

Notes: You create this intent in the Amazon Lex V2 console for the appropriate bot.

The information that you can pass into and retrieve from the Lex V2 bot’s session attributes. Enter the name of the variable and a value to assign. You can add multiple variables, and you can reorder them.

Most commonly, use session variables for bots that start an AWS Lambda Function with the completed intent. This process ensures that the AWS Lambda receives the necessary context for which to perform its operations.

Inputs

Use inputs to pass data to a Lex V2 bot’s session attributes. For each value you send, give the entry a name and an expression that resolves to a string for its value. Then when the action runs, all expressions evaluate to produce the session attributes map that passes to the Lex V2 bot. You can pre-populate slots by choosing the name of what passes as the name of your slot.

• Variable Name
• Value to Assign

Outputs

Use outputs to extract data from the Lex V2 bot’s session attributes. Then in Architect’s Output section, list the names of the parameters you want along with the Architect variables in which to store the matching values.

Note: Key names are case-sensitive.

• Key Name
• Variable to Assign

For more information, see Setting session attributes and Using an AWS Lambda function in the AWS Amazon Lex V2 Developer Guide.

The options that appear in this section reflect the logic configured in the Amazon Lex V2 bot. Each intent represents an action to perform. For example, order a pizza or order flowers. Each intent path matches an output path for the Call Lex V2 Bot action in the task editor.

Below each intent, Architect displays the configured Lex V2 bot slots, or any data the user must provide to fulfill the intent. Using the Pizza Order intent as an example, the slots can include crust type, ingredients, cheese amount, and cutting style. If the user chooses the Order Pizza path, then the Lex V2 bot provides the slots associated with that path.

Select the variables that you want to assign to the failure data values returned by the Lex V2 bot.

Note: To expand or collapse the list of variables, click the arrow next to Failure Outputs.

Configure a matching output for the intent. This path indicates that the action successfully communicated with its external endpoint and received a result. All Lex V2 bot output variables are string types.

Drag the appropriate action below the path that follows the route you want the interaction to take.

To learn more information about them, click the help button next to each intent or slot.

This path indicates that an error occurred while running the action or there was a problem processing the results.  

Note: If the network experiences connectivity issues, the action automatically takes this failure path.

Drag the appropriate action below the Failure path and direct the route you want the interaction to take. For example, a transfer action to send the caller to an agent for assistance.
