Downloading Mods

You can get the full url by appending the download_url to mods.factorio.com, but if you're not authenticated, you will be redirected to mods.factorio.com/login. Logging in to that would give you access to the file. Fortunately, there's a better way to do this. Simply adding username and token parameters to the download url will prevent the redirecting and let you download the file immediately. The token can be acquired from a json file called "player-data.json", located in the User Data directory (see Application_directory#User_data_directory). You can also get the token by using the Web Authentication API.

Example usage: https://mods.factorio.com/{download_url}?username={username}&token={token}
