}

Prepare a JSON file like above that maps the URL given to the argument and the necessary credentials for that connection so that you can connect automatically:

$ iap_curl https://iap-protected.app3.com

Implemented --list-urls options. Thanks to that, you can run the following commands:

$ iap_curl $(iap_curl --list-urls | peco)
