Add the function you want to execure in url_abuse_async.py
Add a route in web/__init__.py. This route will do an async call to the function defined in url_abuse_async.py. The parameter of the function is sent in an POST object
Add a statement in web/templates/url-report.html. The data option is the parameter to pass to the javascript directive
Add a directive in web/static/main.js, it will take care of passing the parameter to the backend and regularly pull for the response of the async call
