Notification Service REST API

Description

The Notification Service REST API is enables you to keep users of your website engaged and informed. You can reach your entire user base quickly and effectively with notifications that are delivered to your web pages. The Notification Service is responsible for delivering the push messages (events) to the Browser Tier. On the Browser Tier, each message is handled by the Notification Agent (a module of the Tracker Application). The Notification Agent provides a list of predefined messages that can be used in engagement scenarios. Each message uses the "gpe." prefix in the channel name.

The Notification Service REST API has two methods:

Notify by Visit ID

Description

This method performs an engagement notification through the Frontend Server by visit ID. If the request is performed correctly, then the Frontend Server creates and sends a notification message to the CometD /notification/{visitId} channel.

Request

Method POST
Body JSON array of Notification Messages
URL http://<frontend_host:frontend_port>/frontend/data/notification/notify/{visitId}

The HTTPS schema is also allowed, if configured.

Parameters
Name Value Mandatory Description
visitId string yes The visit ID for the engagement notification.

Example

Request 

curl -X POST \
  -H "Content-Type: application/json" \
  -d '[{"page": "654E0122924F42EA82B5C581A394555D", "channel": "gpe.appendContent", "data": { "url": "http://www.genesys.com/invite.html", "method": "GET", "container": "body" }}]' \
  http://server:port/frontend/data/notification/notify/654E0122924F42EA82B5C581A394555D

Notification Messages

The notification request body is represented by an array of JSON objects, one object for each notification message: 

[
    {
        // message 1
    },
    {
        // message 2
    },
    ...
]

Message Structure

Notification messages should follow this format: 

{
   "page":"yyy",
   "channel":"any-string",
   "data":{
      "someKey":"someValue"
      ...
   }
}
Option Type Mandatory Default Value Description
page string yes undefined The page attribute can have the following values:
  • <pageId> — The notification message is only received by the page with the unique page ID. For example, 654E0122924F42EA82B5C581A394555D.
  • all — The notification message is received by all pages.
  • active — The notification message is received only by the page with focus in the browser.
channel string yes undefined The channel name. See Standard Messages for details.
data object no undefined Channel-specific data. See Standard Messages for details.

Standard Messages

The following messages are standard in Genesys Web Engagement.

gpe.appendContent

With this message, you can append content retrieved by url to the container element.

Options

Option Type Mandatory Default Value Description
url string yes undefined The path of the resource to load. This option can have either an absolute (http://www.genesys.com/invite.html) or relative value (/invite.html). Note: The relative value is relative to the Frontend Server.
method string no "JSONP" Specifies the type of request to make:
  • GET — You should only use the GET method if the resource is located on the same server, in order to avoid issues with cross-origin resource sharing.
  • JSONP — For the JSONP method, the server you point to in the url option must support the JSONP protocol.
container string no "body" The jQuery selector for the loaded content container. The loaded content is appended to the current element.

Example

The following message uses the AJAX GET request to load data from the server. 

{
    "page": "654E0122924F42EA82B5C581A394555D",
    "channel": "gpe.appendContent",
    "data": {
        "url": "http://www.genesys.com/invite.html",
        "method": "GET",
        "container": "body"
    }
}

gpe.setVariable

You can use this message to set the variable on the page in the window context.

Options

Option Type Mandatory Default Value Description
variable string yes undefined The global variable name. The variable name could contain a namespace, for example: com.service.param — this object will be available by window.com.service.param.
value string no undefined The variable value.

Example

This example sets the variable window.serviceData to the object { 'name': 'Pat', 'message': 'Hello world!' }. If the variable is already defined, then it is extended. 

{
    "page": "654E0122924F42EA82B5C581A394555D",
    "channel": "gpe.setVariable",
    "data": {
        "variable": "serviceData",
        "value": {
            "name": "Pat",
            "message": "Hello world!"
        }
    }
}

gpe.callFunction

This message calls the corresponding function on the page.

Options

Option Type Mandatory Default Value Description
function string yes undefined The name of the function. The name can contain the namespace of the function. For example, com.service.alert — this means that window.com.service.alert() will be called.
arguments array no undefined The arguments to pass to the function. This should always be an array.

Example

This example calls the window.reactToServerMessage('Hello world!', 1) function. 

{
  "page": "654E0122924F42EA82B5C581A394555D",
  "channel": "gpe.callFunction",
  "data": {
    "function": "reactToServerMessage",
    "arguments": ["Hello world!", 1]
  }
}

Using the API to Customize Widgets

You can also use the Notification Service REST API to customize the out-of-the-box Genesys Web Engagement invitation widgets. See the following sections for details:

Chat Invitation Message

The chat invitation message is a JSON object that is sent by Orchestration Server to the browser. The chat invitation is represented by two serial messages: gpe.setVariable and gpe.appendContent.

For example: 

[
   {
      "page":"654E0122924F42EA82B5C581A394555D",
      "channel":"gpe.setVariable",
      "data":{
         "variable":"com.genesyslab.gpe.invite.data",
         "value": {
            "type":"chat",
            "subject":"Chat",
            "message":"Good evening! Would you like some help with the selection? Our technical experts are available to answer questions.",
            "acceptBtnCaption":"Chat",
            "cancelBtnCaption":"No Thanks",
            "inviteTimeout":30,  
            "modal":false,
            "chatOptions": { 
               "serverUrl": "http://demosrv.genesyslab.com:9081/backend/cometd",
               "widgetUrl": "/frontend/resources/chatWidget.html",
               "registration":true,  
               "embedded": false,
               "userData": {
                  "visitID":"3ea3efab-ca33-4383-acbd-90720db72288"
               }
            }
         }
      }
   },
   {
      "page":"654E0122924F42EA82B5C581A394555D",
      "channel": "gpe.appendContent",
      "data": {
         "url": "/frontend/resources/invite.html",        
      }
   }
]

You can use the Notification Service REST API to modify the chat invitation, which uses gpe.setVariable to set the com.genesyslab.gpe.invite.data variable to a list of options. You can update these options to customize the chat invitation. See the table below for details.

Field Type Mandatory Default Value Description
type string yes undefined The type of engagement ("chat" or "callback").
subject string no "Chat", if the type is set to "chat". The invitation widget title.

Callback Invitation Message

The callback invitation message is a JSON object that is sent by Orchestration Server to the browser. The callback invitation is represented by two serial messages: gpe.setVariable and gpe.appendContent.

For example: 

[
   {
      "page":"654E0122924F42EA82B5C581A394555D",
      "channel":"gpe.setVariable",
      "data":{
         "variable":"com.genesyslab.gpe.invite.data",
         "value": {
            "type":"callback",
            "subject":"Voice", 
            "message":"Good evening! Would you like some help with the selection? Our technical experts are available to answer questions.",
            "acceptBtnCaption":"Call Me",
            "cancelBtnCaption":"No Thanks",
            "inviteTimeout":30,

  • cancel
  • acceptChat (deprecated)
  • acceptCallback (deprecated)
pageId string yes The ID of the page where the invitation widget appeared.
visitId string yes The current visit ID.
alias string no Alias of the Frontend Server. Used for Load Balancing. Tracker script holds this parameter in the com.genesyslab.wme.tracker.serverAlias cookie.
