Contex App able to show document from another System

Hello Everyone,

I want to create a widget using an SDK or app design to deploy in a context application. The purpose is to show documents from an external document management system.

My idea is to create something similar to the Infor IDM widget. I want to connect the widget with the JSON information received from the ERP and perform a REST call to the external document management system to get the images to display.

I know how to implement the REST service with ION API and connect a JSON message to a widget. My problem is that I don't know if there is any user interface widget that can help me with this.

Does anyone have any ideas or previous experience with this?

Best regards,

Alessandro
