Steam for Go

Automate actions on the Steam network with Go.

Introduction

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.

This package was originally authored by Philipp15b.

Installation

go get github.com/paralin/go-steam

Usage

You can view the documentation with the godoc tool or online on godoc.org.

You should also take a look at the following sub-packages:

gsbot utilites that make writing bots easier
example bot and its source code
trade for trading
tradeoffer for trade offers
economy/inventory for inventories
tf2 for Team Fortress 2 related things

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:

cd generator
go get -d -v ./
go build -v
./generator clean proto steamlang

Apply the protocol changes where necessary.
