AWS.LexRuntimeV2 — AWS SDK for JavaScript (original) (raw)
We recommend that you migrate to AWS SDK for JavaScript v3. For dates, additional details, and information on how to migrate, please refer to the linked announcement.
Overview
Constructs a service interface object. Each API operation is exposed as a function on service.
Service Description
This section contains documentation for the Amazon Lex V2 Runtime V2 API operations.
Sending a Request Using LexRuntimeV2
var lexruntimev2 = new AWS.LexRuntimeV2();
lexruntimev2.deleteSession(params, function (err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
Locking the API Version
In order to ensure that the LexRuntimeV2 object uses this specific API, you can construct the object by passing the apiVersion
option to the constructor:
var lexruntimev2 = new AWS.LexRuntimeV2({apiVersion: '2020-08-07'});
You can also set the API version globally in AWS.config.apiVersions
using the lexruntimev2 service identifier:
AWS.config.apiVersions = {
lexruntimev2: '2020-08-07',
// other service API versions
};
var lexruntimev2 = new AWS.LexRuntimeV2();
Constructor Summarycollapse
- new AWS.LexRuntimeV2(options = {}) ⇒ Object constructor
Constructs a service object.
Property Summarycollapse
- endpoint ⇒ AWS.Endpoint readwrite
An Endpoint object representing the endpoint URL for service requests.
Properties inherited from AWS.Service
Method Summarycollapse
- deleteSession(params = {}, callback) ⇒ AWS.Request
Removes session information for a specified bot, alias, and user ID. - getSession(params = {}, callback) ⇒ AWS.Request
Returns session information for a specified bot, alias, and user.
For example, you can use this operation to retrieve session information for a user that has left a long-running session in use.
If the bot, alias, or session identifier doesn't exist, Amazon Lex V2 returns aBadRequestException
. - putSession(params = {}, callback) ⇒ AWS.Request
Creates a new session or modifies an existing session with an Amazon Lex V2 bot. - recognizeText(params = {}, callback) ⇒ AWS.Request
Sends user input to Amazon Lex V2. - recognizeUtterance(params = {}, callback) ⇒ AWS.Request
Sends user input to Amazon Lex V2.
Methods inherited from AWS.Service

Constructor Details
new AWS.LexRuntimeV2(options = {}) ⇒ Object
Constructs a service object. This object has one method for each API operation.
Property Details
endpoint ⇒ AWS.Endpoint
Returns an Endpoint object representing the endpoint URL for service requests.
Method Details
deleteSession(params = {}, callback) ⇒ AWS.Request
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.
You don't need to delete a session. Sessions have a time limit and will expire. Set the session time limit when you create the bot. The default is 5 minutes, but you can specify anything between 1 minute and 24 hours.
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
.
getSession(params = {}, callback) ⇒ AWS.Request
Returns session information for a specified bot, alias, and user.
For example, you can use this operation to retrieve session information for a user that has left a long-running session in use.
If the bot, alias, or session identifier doesn't exist, Amazon Lex V2 returns a BadRequestException
. If the locale doesn't exist or is not enabled for the alias, you receive a BadRequestException
.
putSession(params = {}, callback) ⇒ AWS.Request
Creates a new session or modifies an existing session with an Amazon Lex V2 bot. Use this operation to enable your application to set the state of the bot.
recognizeText(params = {}, callback) ⇒ AWS.Request
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.
For more information, see Completion message.
recognizeUtterance(params = {}, callback) ⇒ AWS.Request
Sends user input to Amazon Lex V2. You can send text or speech. Clients use this API to send text and audio requests to Amazon Lex V2 at runtime. Amazon Lex V2 interprets the user input using the machine learning model built for the bot.
The following request fields must be compressed with gzip and then base64 encoded before you send them to Amazon Lex V2.
- requestAttributes
- sessionState
The following response fields are compressed using gzip and then base64 encoded by Amazon Lex V2. Before you can use these fields, you must decode and decompress them.
- inputTranscript
- interpretations
- messages
- requestAttributes
- sessionState
The example contains a Java application that compresses and encodes a Java object to send to Amazon Lex V2, and a second that decodes and decompresses a response from Amazon Lex V2.
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.
