Guest Chat Client - JavaScript

Feature and SDK deprecation: As of 6.11.2025 - Genesys Cloud no longer support ACD Web Chat v2, which is available to customers via all its corresponding Chat Widget versions. This is further to the deprecation of ACD Web Chat v1, which was announced earlier. As a result, Predictive Engagement will also end support for these legacy web chat versions. For more information, see Deprecation: Removal of ACD Web Chat (version 2). All existing customers are encouraged to migrate to Web Messaging and Messenger. As a result, this is the last version of the Guest Chat Javascript SDK.

Using the SDK

Creating a chat

The guest chat APIs do not require standard Genesys Cloud authentication, but do require the JWT to be set for all API calls other than creating a new chat.

const client = platformClient.ApiClient.instance;
let chatInfo, socket;

// Create API instance
const webChatApi = new platformClient.WebChatApi();

const createChatBody = {
  organizationId: '12b1a3fe-7a80-4b50-45fs-df88c0f9efad',
  deploymentId: 'a3e316a7-ec8b-4fe9-5a49-dded9dcc097e',
  routingTarget: {
    targetType: 'QUEUE',
    targetAddress: 'Chat Queue',
  },
  memberInfo: {
    displayName: 'JavaScript Guest',
    profileImageUrl: 'http://yoursite.com/path/to/guest/image.png',
    customFields: {
      firstName: 'John', 
      lastName: 'Doe'
    }
  }
};

// Create chat
webChatApi.postWebchatGuestConversations(createChatBody)
  .then((createChatResponse) => {
    // Store chat info
    chatInfo = createChatResponse;

    // Set JWT
    client.setJwt(chatInfo.jwt);

    // Connect to notifications
    socket = new WebSocket(chatInfo.eventStreamUri);

    // Connection opened
    socket.addEventListener('open', function (event) {
      console.log('WebSocket connected');
    });

    // Listen for messages
    socket.addEventListener('message', function (event) {
      const message = JSON.parse(event.data);

      // Chat message
      if (message.metadata) {
        switch(message.metadata.type) {
          case 'message': {
            // Handle message from member
            break;
          }
          case 'member-change': {
            // Handle member state change
            break;
          }
          default: {
            console.log('Unknown message type: ' + message.metadata.type);
          }
        }
      }

    });
  })
  .catch(console.error);

SDK Logging

Logging of API requests and responses can be controlled by a number of parameters on the Configuration's Logger instance.

log_level values:

1. LTrace (HTTP Method, URL, Request Body, HTTP Status Code, Request Headers, Response Headers)
2. LDebug (HTTP Method, URL, Request Body, HTTP Status Code, Request Headers)
3. LError (HTTP Method, URL, Request Body, Response Body, HTTP Status Code, Request Headers, Response Headers)
4. LNone - default

log_format values:

1. JSON
2. TEXT - default

By default, the request and response bodies are not logged because these can contain PII. Be mindful of this data if choosing to log it.
To log to a file, provide a log_file_path value. SDK users are responsible for the rotation of the log file. This feature is not available in browser-based applications.

Example logging configuration:

client.config.logger.log_level = client.config.logger.logLevelEnum.level.LTrace;
client.config.logger.log_format = client.config.logger.logFormatEnum.formats.JSON;
client.config.logger.log_request_body = true;
client.config.logger.log_response_body = true;
client.config.logger.log_to_console = true;
client.config.logger.log_file_path = "/var/log/javascriptguestsdk.log";

client.config.logger.setLogger(); // To apply above changes

Configuration file

Note: This feature is not available in browser-based applications

A number of configuration parameters can be applied using a configuration file. There are two sources for this file:

1. The SDK will look for %USERPROFILE%\.genesyscloudjavascript-guest\config on Windows if the environment variable USERPROFILE is defined, otherwise uses the path to the profile directory of the current user as home, or $HOME/.genesyscloudjavascript-guest/config on Unix.
2. Provide a valid file path to client.config.setConfigPath()

The SDK will constantly check to see if the config file has been updated, regardless of whether a config file was present at start-up. To disable this behaviour, set client.config.live_reload_config to false.
INI and JSON formats are supported. See below for examples of configuration values in both formats:

INI:

[logging]
log_level = trace
log_format = text
log_to_console = false
log_file_path = /var/log/javascriptguestsdk.log
log_response_body = false
log_request_body = false
[general]
live_reload_config = true
host = https://api.mypurecloud.com

JSON:

{
    "logging": {
        "log_level": "trace",
        "log_format": "text",
        "log_to_console": false,
        "log_file_path": "/var/log/javascriptguestsdk.log",
        "log_response_body": false,
        "log_request_body": false
    },
    "general": {
        "live_reload_config": true,
        "host": "https://api.mypurecloud.com"
    }
}

Environments

If connecting to a Genesys Cloud environment other than mypurecloud.com (e.g. mypurecloud.ie), set the environment on the ApiClient instance.

const client = platformClient.ApiClient.instance;
client.setEnvironment(platformClient.PureCloudRegionHosts.eu_west_1);

Making Requests

All API requests return a Promise which resolves to the response body, otherwise it rejects with an error. After setting the JWT, the following code will make an authenticated request:

// Create API instance
const webChatApi = new platformClient.WebChatApi();

// Authenticate
webChatApi.postWebchatGuestConversations(createChatBody)
  .then(() => { 
    // Set JWT
    platformClient.ApiClient.instance.setJwt(chatInfo.jwt);

    // Send a message
    return webChatApi.postWebchatGuestConversationMemberMessages(chatInfo.id, chatInfo.member.id, { 
      body: 'Message from chat guest' 
    });
  })
  .then(() => {
    // Message sent
  })
  .catch((err) => {
    // Handle failure response
    console.log(err);
  });

Extended Responses

By default, the SDK will return only the response body as the result of an API function call. To retrieve additional information about the response, enable extended responses. This will return the extended response for all API function calls:

const client = platformClient.ApiClient.instance;
client.setReturnExtendedResponses(true);

Extended response object example (body and text have been truncated):

{
  "status": 200,
  "statusText": "",
  "headers": {
    "pragma": "no-cache",
    "inin-correlation-id": "ec35f2a8-289b-42d4-8893-c50eaf81a3c1",
    "content-type": "application/json",
    "cache-control": "no-cache, no-store, must-revalidate",
    "expires": "0"
  },
  "body": {},
  "text": "",
  "error": null
}

Using a Proxy (Node.js only)

Using a proxy is accomplished by setting the proxy settings on the client object

NOTE: SDK proxy configuration is only available in the node.js package due to the axios proxy incompatibility with browsers.

const client = platformClient.ApiClient.instance;
// Documentation: https://axios-http.com/docs/req_config
client.proxy = {
  host: '172.1.1.100',
  port: 443,
  protocol: 'https',
  auth: {
    username: 'john_doe',
    password: 'abc123'
  }
};

Error Responses

Error responses will always be thrown as an extended response object. Note that the error property will contain a JavaScript Error object.

Example error response object:

{
  "status": 404,
  "statusText": "",
  "headers": {
    "pragma": "no-cache",
    "inin-correlation-id": "d11bd3b3-ab7e-4fd4-9687-d04af9f30a63",
    "content-type": "application/json",
    "cache-control": "no-cache, no-store, must-revalidate",
    "expires": "0"
  },
  "body": {
    "status": 404,
    "code": "not.found",
    "message": "The requested operation failed with status 404",
    "contextId": "d11bd3b3-ab7e-4fd4-9687-d04af9f30a63",
    "details": [],
    "errors": []
  },
  "text": "{\"status\":404,\"code\":\"not.found\",\"message\":\"The requested operation failed with status 404\",\"contextId\":\"d11bd3b3-ab7e-4fd4-9687-d04af9f30a63\",\"details\":[],\"errors\":[]}",
  "error": {
    "original": null
  }
}

Versioning

The SDK's version is incremented according to the Semantic Versioning Specification. The decision to increment version numbers is determined by diffing the Platform API's swagger for automated builds, and optionally forcing a version bump when a build is triggered manually (e.g. releasing a bugfix).

Support

This package is intended to be forwards compatible with v2 of Genesys Cloud's Platform API. While the general policy for the API is not to introduce breaking changes, there are certain additions and changes to the API that cause breaking changes for the SDK, often due to the way the API is expressed in its swagger definition. Because of this, the SDK can have a major version bump while the API remains at major version 2. While the SDK is intended to be forward compatible, patches will only be released to the latest version. For these reasons, it is strongly recommended that all applications using this SDK are kept up to date and use the latest version of the SDK.
