Chat API Version 1

Important
This API is documented to support older deployments. Genesys recommends that you upgrade to Chat API version 2 if you are still using Chat API version 1.

Prerequisites

Before using the Chat API described on this page, you must configure your Genesys Mobile Services deployment correctly. Then, before you can create Chat sessions, you must create your chat service (of type ors or builtin) with the Service Management UI. Then, you will be able to use this chat service to request chat session IDs.

Getting Started

The Chat API is used by customer-facing applications to create and manage a chat session associated with contact center-related services.

Basic Chat

To start chat session:

  • Create the built-in service of type request-chat that provides the Basic Chat Service API.
  • Use the Basic Chat Service API to create a Chat Service ID for each chat session. The built-in request-chat service created in the Service Management UI provides the Basic Chat Service API.

Then, you can use the Chat Service ID to perform queries for your chat session.

GMS-request-chat-session.png


Chat API Version 1 (Genesys Mobile Services-Based) allows an application to pass business context data in the service creation request, using the fixed service name request-chat.

  • No corresponding Orchestration Server (ORS) session will be created.
  • Data is preserved by Genesys Mobile Services using the specified time-to-live parameter (or the configured default value).
  • Chat interaction could be initiated by an application at any point.
  • The routing logic associated with the specified interaction endpoint (or the configured default value) would be responsible for finding an appropriate agent.
  • Both polling and async (CometD) modes of message delivery are supported.
  • Applications can handle background state through chat push notifications
Tip
When using asynchronous messaging with CometD, all HTTP headers must include the gms_user header.


ORS-Chat Services

Instead of creating a basic chat service to request chat session IDs, you can configure one of the following chat service of type ors in the Service Management UI:

Then, use this ors service to retrieve your new service ID associated with your chat session. For instance if you configured the chat-immediate service, you will post to the chat-immediate service: 

POST http://localhost:8080/genesys/1/service/callback/chat-immediate

You can now use this ID in the Chat Interaction APIs.


Structures

The Chat API uses the data structures described in this section (in JSON format) to exchange data. Requests are accepted in application/json, 'application/x-www-form-urlencoded', or 'multipart/form-data' formats, and responses are returned in 'application/json' format. If an expected value is missing or incorrect, then your application receives a 415 (Unsupported Media Type) error.

JSON-Encoding

For each method detailed below, if you wish to use JSON in your body, you must use JSON-encoding for body capabilities by setting the Content-Type to application/json;charset=UTF-8. For example, if you use the query for the chat session creation:

Request 

POST http://localhost:8080/genesys/1/service/fb80ed7b-a164-46ef-a5b8-f14f99236042/ixn/chat HTTP/1.1

}
Warning
The current implementation supports simple key/value parameters. You cannot manage complex JSON-structured values such as maps and arrays. See the above code example above.


Chat Interaction API Resources

The chat interaction is used to represent the current state of the chat session and transcript. This information is returned in the HTTP response of each API request in poll mode or delivered asynchronously in push mode (CometD).

Important
You need to create the service session with the basic chat service before you can create a chat interaction. Since 8.5.1, you can specify push notification parameters to manage your application's background state (see sections below).

The Chat Interaction Attributes are the following:

  • chatIxnState – The current state of the chat session.
  • chatSessionId – Session ID associated with the chat.
  • transcriptPosition – The current position in the chat dialog or transcript for this user.
  • chatServiceMessage – A diagnostic message used for debugging.

The following are only returned if the _verbose parameter in the API request is true:

  • userId – User ID assigned by the Genesys Chat Server.
  • secureKey – The security key for this chat session.
  • checkChatServiceLoadBalancer – Indicates that we should check the chat load balancer for the appropriate Chat Server to use.
  • PathchatServerLoadBalancerAlias – The alias for the Chat Server that is assigned to this chat session by the Chat Server load balancer.
  • chatServerHost – Host name for the Chat Server assigned to this chat session from the Chat Server load balancer.
  • chatWebApiPort – Port number of the Chat Server load balancer
  • isTLSrequired – Indicates whether a TLS connection is required for the Chat Server.
  • clientTimeZoneOffset – Time zone offset specified by the user client. Could be used to convert UTC time returned by server into user local time.
  • _chatIxnAPI_SEND_URL – URL used to send chat messages for this chat session.
  • _chatIxnAPI_REFRESH_URL – URL used to refresh the chat transcript for this chat session.
  • _chatIxnAPI_START_TYPING_URL – URL used to indicate that the user started typing a chat message for this chat session.
  • _chatIxnAPI_STOP_TYPING_URL – URL used to indicate that the user stopped typing a chat message for this chat session.
  • _chatIxnAPI_DISCONNECT_URL – URL used to disconnect the user from the chat session.
  • _chatIxnAPI_REFRESH_FROM_START_URL – URL used to refresh the chat transcript from the beginning of the session.
  • _chatIxnAPI_SEND_CUSTOM_URL – URL used to send a custom notice to the chat session.

Chat Transcript Resource

The Chat Transcript Attributes are the following:

  • startedAt - Chat interaction start time (in UTC).
  • transcriptToShow - An ordered array of transcript events. Each event is represented by another array of the following format:
    [{Event type}, {Agent nickname}, {Chat message}, {Number of seconds from interaction start}, {Type of user}, {message index}] where:
    • Event type: {"Message.Text", "Notice.Joined", "Notice.Left", "Notice.TypingStart", "Notice.TypingStop", "Notice.PushUrl"}
    • Type of user: {"AGENT", "CLIENT", "EXTERNAL"}


Starting in 8.5.105, the message index field has been added to the chat message to indicate the position of each message in the transcript. Your chat client application can now manage the comet and the API response channel and merge the messages according to their index in the transcript. This will avoid duplicate messages on screen. To enable this message index, configure enable-fast-chat-transcript-refresh = true in the chat section of your GMS configuration.

This example shows how to send messages with their transcript position: 

$ curl --data "transcriptPosition=1&message=good"
 http://localhost:8080/genesys/1/service
/9f704400-7967-4586-821e-2e2ad5c1585f/ixn/chat/send
{

 "transcriptPosition" : "3",
 "chatSessionId" : "000F7aBK86UC001F",
 "transcriptToShow" : 
[["Notice.Joined","Kristi Sippola","has joined the session",
"21","AGENT","2"],
["Message.Text","127.0.0.1","good","35","CLIENT","3"]],
 "startedAt" : "2016-06-01T14:51:37Z"
}

$ curl --data "transcriptPosition=4&message=right" 
http://localhost:8080/genesys/1/service
/9f704400-7967-4586-821e-2e2ad5c1585f/ixn/chat/send

{
 "chatIxnState" : "TRANSCRIPT",
 "transcriptPosition" : "15",
 "chatSessionId" : "000F7aBK86UC001F",
 "transcriptToShow" : 
 [["Notice.TypingStarted","Kristi Sippola",
"user is typing","55","AGENT","5"],
["Message.Text","Kristi Sippola","position 2","57","AGENT","6"],
["Notice.TypingStarted","Kristi Sippola",
"user is typing","57","AGENT","7"],
["Message.Text","Kristi Sippola","hello","57","AGENT","8"],
["Notice.TypingStarted","Kristi Sippola",
"user is typing","58","AGENT","9"],
["Message.Text","Kristi Sippola","allo","58","AGENT","10"],
["Notice.TypingStarted","Kristi Sippola",
"user is typing","58","AGENT","11"],
["Message.Text","Kristi Sippola","bonjour","58","AGENT","12"],
["Notice.TypingStarted","Kristi Sippola",
"user is typing","58","AGENT","13"],
["Message.Text","Kristi Sippola","Hallo","59","AGENT","14"],
["Message.Text","127.0.0.1","right","65","CLIENT","15"]],
 "startedAt" : "2016-06-01T14:51:37Z"
}
Important
The index data set of the transcript allows missing numbers due to configurable filtering events system. For example, if you have index series like "1, 3, 4, 5, 7", the unavailable "2, 6" index numbers can be filtered events).

Quick Start Examples

The following quick start examples show how you can establish a CometD connection to receive asynchronous notification, and how to create a service.

Using CometD to Receive Event Updates

If you are using CometD to get event updates on the chat session then you need to set up a CometD connection with a subscription for /_genesys. You also need to make sure 'gms_user' header in all cometd related requests is set to the value uniquely representing application end user. Typically this value would be setup (or at least verified) by security gateway located between the client application and GMS.

Create chat interaction using same sessionid:

To create a chat interaction that is associated with a service, a ixn/chat request is sent with the parameters to initiate the chat session.

Parameter Name Mandatory Description
firstName no First name of the user. If provided will be attached as fldnFirstName to the chat interaction.
lastName no Last name of the user. If provided will be attached as fldnLastName to the chat interaction.
email no e-Mail address of the subject. If provided will be attached as fldnEmailAddress to the chat interaction.
subject yes Subject of the service and chat session.
userDisplayName no Available since GMS 8.1.100.27. Nickname to be displayed in the chat conversation.
notify_by no If using a CometD connection for the asynchronous receiving of chat messages, then supply this parameter with the value "comet".
push_notification_deviceid no Device ID to use for chat push notifications (used to manage background state). If not specified, push notifications are disabled.
push_notification_type no Device Type to use for chat push notification. Possible values are: ios, gcm, android, comet, httpcb, orscb.
push_notification_debug no Set to true to enable debug push notifications in the GMS server. Default value is false.
push_notification_language no Set the language to use for chat push notifications. (See localisation instructions here )
push_notification_maxsize no Limit the payload size of push notifications messages. If you do not add the push_notification_maxsize parameter to your query, the payload size is set to 4096 bytes by default.
Tip
For iOS version 7 and earlier, your iOS device limits the push notification payload size to 256 bytes. Set this parameter to 256 to ensure correct push notifications.

Chat Push Notification and Background State

Mobile Application Background State Issues

If an iOS or Android mobile application is moved to the background state, the operating system does not close active TCP connections. So, if your app does not handle the foreground and background events, the server-side of your CometD connection isn't notified.

More specifically, if your app handles chat with GMS, the agent may send a new message which would result in sending the long poll response. Here is a list of the various scenarios which can happen according to your implementation.

  • The Cometd server attempts to send long poll response but fails and closes socket of current long-poll request.
  • The Cometd server sets a 10 second timer; if the app does not reconnect within this period, the app is considered to be gone and its context is destroyed.

Later, if the app returns to the foreground, it does not receive chat notifications from the Cometd server and the chat session appears to be broken.

To avoid these type of issues, your app should listen for events that both iOS and Android submit when your app enters the background (or foreground) state. See the Official documentation.

  • Apple provides background instructions for iOS, here.
  • Android provides best background practices here.

Then, your app should implement the Cometd Meta Disconnect message detailed below to handle background State issues.

Cometd Meta Disconnect Messages

To handle background state, your app must send Cometd /meta/disconnect messages to GMS and later, if your app returns to foreground, it should establish a new Cometd session as detailed below.

  1. When your app enters the background state, it sends a Comet/meta/disconnect message to GMS which includes the highest transcript position received by your app, as for example: 
    {
   "channel": "/meta/disconnect",
   "clientId":  "71k6evjfbffqq9eir3jhn6udxz",
   "ext:
   {
        "transcriptPosition": "4"
   },
   "id": "4"
}
  2. If GMS receives a /meta/disconnect message, it flags your app as disconnected and sends a chat Notice.Custom event to the agent. The default value is customer is not online. You can configure this text.
    1. Edit your GMS application (with Configuration Manager for example).
    2. Navigate to Options > Service.<service_name>.
    3. Edit the _agent_timeout_notification_message value.
  3. If the agent sends a new message while your app is disconnected, GMS starts a configurable timer. You can set this timer value to zero
    1. Edit your GMS application (with Configuration Manager for example).
    2. Navigate to Options > Service.<service_name>.
    3. Edit the _client_timeout_notification value.
    When the timer expires, GMS sends a push notification (iOS apns, Android gcm, or http). Typically, the notification results in a dialog which allows the user to optionally return the app to the foreground.
  4. The chat session may have ended when the app returns to the foreground, either because the agent left the session or because the session timed out as a result of user inactivity. In that case, the app no longer receives Cometd notifications. To detect if the session has ended, call the Chat Refresh Chat API – it will return a 4xx reply to indicate that a session has ended.
  5. When the app returns to the foreground and if the session has not ended, it must start a new Cometd session with GMS. GMS flags the app as connected and sends a Cometd notification that includes all chat transcript events that occurred after the app entered the background state, as for example: 
    [
   {
      "data":{
         "id":"fdf93730c1e411e4a5e8f1be76b28efd",
         "message":
            { "chatSessionId":"0001BaAFC4J8000N", 
"transcriptPosition":"6", 
"chatServiceMessage":"Chat service is available",
 "startedAt":"2015-03-03T20:36:12Z",
 "chatIxnState":"TRANSCRIPT", "transcriptToShow":
[ ["Notice.TypingStarted","agentName","is typing","28","AGENT"],
["Message.Text","agentName","Hello","29","AGENT"] ] },
"tag":"service.chat.refresh.180-655e104c-a6cf-447d-b94b-f132d49a35fe"
      },
      "channel":"/_genesys"
   },
   { "successful":true, "channel":"/meta/connect" }
]
Important
  • If your app returns to foreground before the timer expires, no push notification is sent, but your app must still start a new Cometd session and it will receive a Cometd notification (which includes all new transcript data) from GMS.
  • If your app does not return to foreground after the first push notification is sent, GMS sends additional push notification messages for each new agent event. Note that these events are sent immediately.

Content of Push Notification Messages

GMS triggers push notification messages if the agent submits new chat events to the app flagged as disconnected. The following events can result in a notification:

  • Notice.TypingStarted
  • Notice.TypingStopped
  • Notice.Joined
  • Notice.Left
  • Notice.PushUrl
  • Notice.Custom
  • Message.Text

Your application's configuration includes a filter to exclude events from triggering a push notification. The filtering_chat_events option in the push section sets the default value for this filter to Notice.TypingStarted,Notice.TypingStopped. You can still set a different value for your service.

  1. Edit your GMS application (with Configuration Manager for example).
  2. Navigate to Options > Service.<service_name>.
  3. Edit the _filtering_chat_events option to add new event types to exclude.

For the Android and http push notification types, notification messages include the content of the filtered agent events.

The following example of the push notification message includes the content of the filtered agent events. 

"message": {
  "message": "New message from Agent",
  "serviceId": "180-e941460d-1eb0-4f0b-9022-b99ca9ee41f7",
  "lastTranscript": [
     {"Message.Text": "A line of text."}
     {"Message.Text": "Another line of text."}
  ]
}

By default, the message attribute (or notification message) is set to New message from Agent, but you can change this text in your service options.

  1. Edit your GMS application (with Configuration Manager for example).
  2. Navigate to Options > Service.<service_name>.
  3. Edit the value of the _client_timeout_notification_message option.

The notification is tagged as chat.newagentmessage. In addition to the notification message, the notification content provides the lastTranscript text that can be displayed to the user.

  • You can display this the lastTranscript text in a popup a or banner notification to the user.

    • GMS Chat Push iOS.PNG

Specific Configuration for Chat Push Notification

To customize your GMS configuration for push notification messages (for both iOS and Android), you can create a push.provider.event.chat.newagentmessage section in the Options tab (with Configuration Manager for instance). You can add there any of your Android or iOS options.

  • This additional configuration is not mandatory.
Tip
  • Read more about options of the GMS push section here.
  • Read more about the OS specific capabilities associated with the notification message here.


CometD and Loss of Network Connection

Mobile devices are subject to temporary loss of carrier or wifi network connectivity. If this occurs when a chat session is active, the mobile device may not receive CometD transcription notifications that occurred during or around the time of the loss.

The mobile device CometD client should detect when network connectivity has been lost; for example, the current long-poll request will return an error. When this occurs, the CometD client should establish a new session starting with a handshake sequence. To support the mobile client informing GMS on the transcription notifications already received, the first /meta/connect message that is sent after the handshake can optionally include the client's transcriptPosition in the ext component. An example connect message is shown below. 

POST  http://localhost:8080/genesys/cometd 
Accept-Encoding: gzip,deflate 
Content-Type: application/json;charset=UTF-8
gms_user: BuzzBrain

{
   "channel": "/meta/connect",
   "clientId": "44xkkazwfabw73jrvjsvoy4ul",
   "connectionType": "long-polling"
   "advice": {
        "timeout": 0
   },
  "ext": {
    "transcriptPosition": "14"
  },
   "id": "1"
}

If the transcriptPosition is provided this way the next CometD notification sent by GMS will include transcript content starting at the next position, so the client will only receive the content that was missed due to the network connection loss.

Note, If the transcriptPosition is not provided in the /meta/connect after a network loss, GMS will estimate the client transcriptPosition based on the timing of the loss of network connection. Typically this will result in the next CometD notification including some transcript content that was previously received, but could also result in the transcript content starting at an offset greater than what was received. If the client does not provide the transcriptPosition upon reconnecting after a network connection loss, it is recommended to call the refresh API function to reset the local transcript display.
