Steam for Go

This library implements Steam's protocol to allow automation of different actions on Steam without running an actual Steam client. It is based on SteamKit2, a .NET library.

In addition, it contains APIs to Steam Community features, like trade offers and inventories.

Some of the currently implemented features:

  • Trading and trade offers, including inventories and notifications
  • Friend and group management
  • Chatting with friends
  • Persona states (online, offline, looking to trade, etc.)
  • SteamGuard with two-factor authentication
  • Team Fortress 2: Crafting, moving, naming and deleting items

If this is useful to you, there's also the go-steamapi package that wraps some of the official Steam Web API's types.

Working with go-steam

Whether you want to develop your own Steam bot or directly work on go-steam itself, there are are few things to know.

  • If something is not working, check first if the same operation works (under the same conditions!) in the Steam client on that account. Maybe there's something go-steam doesn't handle correctly or you're missing a warning that's not obviously shown in go-steam. This is particularly important when working with trading since there are restrictions, for example newly authorized devices will not be able to trade for seven days.
  • Since Steam does not maintain a public API for most of the things go-steam implements, you can expect that sometimes things break randomly. Especially the trade and tradeoffer packages have been affected in the past.
  • Always gather as much information as possible. When you file an issue, be as precise and complete as you can. This makes debugging way easier.
  • If you haven't noticed yet, expect to find lots of things out yourself. Debugging can be complicated and Steam's internals are too.
  • Sometimes things break and other SteamKit ports are fixed already. Maybe take a look what people are saying over there? There's also the SteamKit IRC channel.

Updating go-steam to a new SteamKit version

To update go-steam to a new version of SteamKit, do the following:

go get
git submodule init && git submodule update
cd generator
go run generator.go clean proto steamlang

Make sure that $GOPATH/bin / protoc-gen-go is in your $PATH. You'll also need protoc, the protocol buffer compiler. At the moment, we use Protocol Buffers 2.6.1 with proco-gen-go-2402d76.

To compile the Steam Language files, you also need the .NET Framework on Windows or mono on other operating systems.

Apply the protocol changes where necessary.
