That build hook URL for Netlify requires a POST request. But Drummer lets you run a script from the Iconbar. Here's mine.

const xhr = new XMLHttpRequest();

const hookUrl="https://api.netlify.com/build_hooks/XXX" // XXX is given to you by Netlify

xhr.open("POST", hookUrl, true);

xhr.setRequestHeader('Content-Type', 'application/json');

xhr.send(JSON.stringify({}));
