Attached is an example of the code which needs to be implemented on the client side. The following configuration steps should be taken to implement this feature:

1. Navigate to the Digital Messaging manager, Channels and Interfaces > Digital Messaging > Connection > Manage Connections
   1. Within the Digital Messaging Manager, navigate to the active Web Messaging connection and head to the security tab. In the security tab, enable the configuration ‘Control chat session initialization’ seen in the screenshot
   2. 
2. On the client side page, refer to the sample application attached, as the following logic should be implemented
   1. Using the JWT secret on the same security page in Digital Messaging manager, create a request to create a session signed with JWT token:
3. reateNewPrivateChatSession = async(uuid,proactive_trigger) => {
4.  
5.   var token = generateJWTToken(MESSAGING_WIDGET_ID);
6.  
7.   const options = {
8.     headers: {
9.       'Content-Type': 'application/json',
10.       'authorization': 'Bearer ' + token
11.     }
12.   };

b. Once the session has been created, retrieve the Session ID

      response = await axios.post('https://widget.chat.pega.digital/' + MESSAGING_WIDGET_ID + '/create', data, options);  

      let sessionId = response.data.sessionId;

      console.log("generated session ID: " + sessionId +  " for customerId " + (uuid ? uuid : "anonymous"));

      console.log("proactiveTrigger: " + proactive_trigger);  

      return sessionId;

  }

c.             Finally, call the Private Data API and send over the Session ID and customer identifier, which will be exchanged into the Pega Appliction alongside the incoming messages. The customer identifier will be seen in the messaging interaction under ‘pyCustomerPrivateData’

//Call private data API in digital messaging

 callPrivateDataAPI = async(arg_sessionId, uuid) => {

  var token = generateJWTToken(arg_sessionId);

  const options = {

    headers: {

      'Content-Type': 'application/json',

      'authorization': 'Bearer ' + token

    }

  };

  //make request

  try{

    var res = await axios.post('https://widget.chat.pega.digital/4d88d63c-b3d9-49ee-8f77-adeb5d4fc223/widget.js', { customerId: uuid }, options);

  } catch(err){

    console.log(err);

  }

}
