ADF data ingestion from web application

Hello everyone

Today I'm facing a challenge with one of my customers. He has an ERP (enterprise resource plan) contracted from a local comapany in Brazil. http://www.vhsys.com.br and this plattafom does not offer very much resource to dig in his data, I am wondering if is it possible to ingest data from this web application by ADF and then connect with PowerBI, after this data will be hosted into Azure

I have read a lot of blogs and microsoft documentation and I can't find some solution to this

Thanks in advance
