How do you get data from a data logger, from valueclouds.com (Solar inverter related)

I have recently bought a 6kW solar inverter. it has wifi connectivity through a separate USB dongle (valueclouds.com). although it has a dedicated android app and a web page, I want to develop my own android app with customized dashboards.

How to get that data from the data logger?

If it supports api, kindly share the documentation to process further
