Put the script on server and gave any trusted guy to test. Your script will also be safe and also you gain trust reviews.
Hello thank you so much for advice but brother I already put script on my Customer PC (Localhost) and i setup first i just take money for API integration .
Okay great that you put on localhost. But you can give the host address to others for test. I don't think anyone can steal the script if hosted.
sure I can do that..
