The Dashboard Engine allows dashboards to be created from gadgets built on datasources, which are translated into queries on the platform Entities. At the execution level, the browser establishes a communication with the Dashboard Engine to pass parameters and retrieve information.

In previous versions the **communication could be WebSockets or XHR in Fallback mode.** For the type of application, WebSockets communication is ideal because it establishes a secure channel between the client and the server. However, in some scenarios this communication poses problems in the face of peripheral security elements such as WAFs.

For this reason, a n**ew REST communication channel has been implemented in the Dashboard Engine.**

Once this working mode of the Dashboard Engine is activated, the operation is transparent to the developer and end user of the dashboards.
