Communication between applications through Websockets
Hi
I have a requirement where I have to launch a non-pega external application inside my pega application on a button click which opens a separate browser to show the external app. User can perform some changes like customer name change or contact details change etc. in the external application. User may or may not close the external app window and use both the pega app and external app in parallel. Given this, if the user changes the name or contact details in the external app, pega UI should refresh its screen and show the updated details instantly. Is there a way to achieve this? I heard websockets can be used for applications to communicate with each other so that external app can notify if there are changes which needs to be notified.
Note: Users dont like to have a manual refresh button OR open the external application in the modal window.
Please advice if anyone handled such requirement or any other idea other than websockets.

Hi Divya - Thanks for the response. I believe mashup is an option if I need to embed pega app into the external app. In my case, I want the two applications to run separtely but any change made by Non-pega (reactJS) external application should instantly refreshed on pega screen.
Just to give some background, we have a CPM based call centre application in pega which launches an external billing application built with ReactJS. When some of the billing info changed thru reactjs application, pega screens needs to be refreshed. There are certain billing changes where in I need to kill the interaction created in pega etc. I am looking for some mechanism which can be used by these apps to communicate with each other.
Thanks

I have a query:
How are you getting details from billing application (why because, if there is a change in billing application, how will pega knows that)
Based on this, we can design the solution.

This post is all about finding the approach to it. I heard websockets can be used for two different applications to communicate.I am not sure how to achieve this.
Thanks

Websockets would be appropriate for client (browser) server communication, such as pushing a notification to (browser, mobile app) from server. For the requirement you described, you need client side communication between two applications, which can be achieved by using Javascript postMessage method. The External application can post a message to PEGA application window, the dispatched message can be picked by a Javascript event listener on PEGA application and trigger a local refresh.
