please help me – I need to send requests to an API that runs on an insecure HTTP protocol. Unfortunately, I can’t use PHP, but I have to use AJAX (the API server runs on localhost), so only a device connected to the same network can access it. However, the browser reports blocked mixed content.

I found something about CSR, but I can’t set it up at all.

This is the connection of the payment terminal to the e-shop. Script runs from the e-shop administration and employee should be able to control it on the same network from a PC, or even a mobile phone without settings the browser.

Could you please advise me how to ideally solve this? Thank you very much for your help. 🙂
