I'm implementing PayU payment module in my Meteor app. Flow works well, it shows proper order view and it redirects to proper continueUrl. In PayU API there is also notifyUrl and PayU can send POST request to that url if there is change in order's status. When there is, for example COMPLETED status I should execute update in mongoDB and change user's account type.
But I don't have any idea how to make it. Should I make html file on meteor's server side? If it's possible what link should I pass in notifyUrl to make PayU request pass to that html file?
