In CTLive, it is possible to request the transcript of the current chat or a chat already archived in the system.
Depending on the scenario you want to implement, the CTLive Agent SDK provides specific APIs/WS to retrieve the chat transcript.
Transcript of an active chat
During the engagement phase (joinContact) of a chat can ben useful to retreive all messages that were previously sent into the chat, before the agent start to writing. This includes interactions with automated systems such as BOTs and IVR logic.
The best moment to retreive the messages transcript is when the agent is joining a new chat, on the joinContact callback event.
LIVECHATSDK.LIVECHAT.joinContact(<chat_id>, <nickname>).then(
function (contact) {
LIVECHATSDK.LIVECHAT.getChatHistory(contact.contact.id, true).then(
function(data) {
if (data.messages.length > 0) {
for (var i = 0; i < data.messages.length; i++) {
// The data.messages[i].data.messageType can be:
// TEXT, IMAGE, LINK, MENU, MENU_RESPONSE,
// DOCUMENT, AUDIO, VIDEO, LOCATION, REPLY_TO_STORY,
// STORY_MENTION, QUICK_REPLY, QUICK_REPLY_RESPONSE
// (some message types are related to specific features offered
// by some media channels like Meta, Istagram o DialogFlow)
if ( data.messages[i].data.messageType === "TEXT" ) {
/* Text Message...call your custom function that render the message
using the following properties:
data.messages[i].data.content.user.nickname: agent/customer nickname
data.messages[i].data.content.text: the text of the message
data.messages[i].data.content.user.isAgent: boolean to identify agent or customer
data.messages[i].data.id: unique ID of the message
data.messages[i].data.ts: timestamp
}
}
}
}
);
}
);
Transcript of an archived chat
For better customer management, it might be useful to access all interactions that a specific UserID has carried out across multiple chat sessions on different agents.
To this purpose, CTLive provides a service that allows retrieving all archived chats for a specific customer with an unique user ID.
The service can be called with a simple Ajax GET request. An authenticated token session must be provided.
jQuery.ajax(
{
type: "GET",
async: true,
url: "/livechat/" + <TENANT_NAME> + "/getChatTranscriptByUserID/" + <USER_ID>,
dataType: "json",
headers: {
"ctlivetoken": <CTLIVE_VALID_SESSION_TOKEN>
}
}
The response contains an array object with all the archived chat and messages.
for (var i = 0; i < data.chatTranscripts.length; i++ ) {
// data.chatTranscripts[i] is an object that contains the following information:
// data.chatTranscripts[i].transcript.messages: all the messages sent on a single archived chat
// data.chatTranscripts[i].transcript.room: CTLive chat room ID
// Get all messages:
for (z = 0; z < data.chatTranscripts[i].transcript.messages.length; z++) {
switch (data.chatTranscripts[i].transcript.messages[z].data.messageType) {
case "TEXT":
/* Text Message...call your custom function that render the message
using the following properties:
data.chatTranscripts[i].transcript.messages[z].data.id: unique message ID
data.chatTranscripts[i].transcript.messages[z].data.content.text : the content of the message
data.chatTranscripts[i].transcript.messages[z].data.content.user.isAgent: boolean to identify agent or customer
data.chatTranscripts[i].transcript.messages[z].data.content.user.id : unique ID of the user
data.chatTranscripts[i].transcript.messages[z].data.ts: timestamp of the message
data.chatTranscripts[i].transcript.messages[z].data.deliveryErrorReason: if 'deliverySuccess' is false this propert contains the delivery error reason
data.chatTranscripts[i].transcript.messages[z].data.deliverySuccess: boolean used to identify if the message war delivered successfully
*/
break;
};
}
}
In the case of an attachment (image, document, audio and video message types) the message will not contain the binary content of the sent file but a reference to it (message.id). An additional web service provided by CTLive must be used to retrieve the file's content.
A two-step process can be useful for retrieving the binary content of an attachment to avoid overloading the page rendering time due to multiple requests to CTLive for large file content.
First of allyou can display only a reference to the file represented by an icon.:
When the user clicks on the icon the file content can ben requested using the 'getMultimediaMessageByMessageID' web service and specifying the original document ID that is stored into the transcript message:
jQuery.ajax(
{
type: "GET",
async: true,
url: "/livechat/" + <TENANT_NAME> + "/getMultimediaMessageByMessageID/" + <IMAGE_ID>,
dataType: "json",
headers: {
"ctlivetoken": <CTLIVE_VALID_SESSION_TOKEN>
}
}
).done(
function (data) {
if (data.result == true) {
// File binary content is stored in Base64 format
jQuery( "#imgChatHistory").attr("src", "data:image/jpeg;base64, " + data.message.messages[0].content.img);
}
}
);
The result when the document has been retreived….
The attached file can also ben downloaded by simply using an HTML anchor tag that refers to the ‘downloadTranscriptDocument’ service offered by CTLive. You have to specify in the service’s URL the unique document ID and a valida CTLive authenticatd token passed by the ‘ctlivetoken’ querystring param.
