I wrote a web application on Google app script and it works, but for implementation I need to get an API key, to get it I need a white list of ip addresses, unfortunately the
UrlFetchApp.fetch
command has too wide a range of them.
I don't know how to solve this problem maybe you can use a proxy server? Or if you now how i can use Google cloud for get static ip for my app csript or general static ip for app script
