Mod Portal API authentication

So I found there's a nifty mod portal API, and it would be tremendously helpful for automating mod updates on my server. However, download links require me to log in first. Is there a way to log in via some tool?
Can we expect the mod portal API to be documented in near future?

I'm not aware of how to authenticate with the server given just a username and password (it was a painful few days trying to figure it out). However, if you've already authenticated with the server (such as through the game), you can use the username and token (it's saved in a json file) to make downloads. So just like this:
1) Get the service-username/service-token from the game (located in player-data.json, should be in the appData folder).
2) Get the download link of the mod you want, and append the user/token to it (it's a get request). It should look like this:
https://mods.factorio.com/${mod download link}?username=${playerUsername}&token=${playerToken}

Thanks, this will be useful for testing!
A proper auth API would definitely be better...

Just for reference, I noticed that the commandline mod tool:
viewtopic.php?f=137&t=29509
Has a the authentication login implemented at:

Well spotted. Thanks a lot! It will definitely be very helpful.
I hope there will be some official docs for all the APIs by the time game comes out.

I was trying everything, like putting a browser in my program to let the user login and now your telling me it's as easy as this!?
(I feel stupid now, I should have googled earlier)

To be fair, the browser is probably a little bit more reliable than undocumented APIs that can change on a moment's notice

You can not authenticate using the password. However, you can get the token from the password by sending a POST request to
Code: Select all
https://auth.factorio.com/api-login
with this content:
Code: Select all
require_game_ownership=True&username=<username>&password=<password>
This way you don't need to rely on the user being logged in with Factorio.
