Steam Trade Offers for Node.js

steam-tradeoffers is a library for Node.js written in JavaScript. It allows you to automate Steam trading using trade offers. It was designed with node-steam in mind, but does not depend on it directly. Some of the methods of the library are wrappers for Steam Web API.

Please read the FAQ first if you have any questions.

If your question is not answered here, please ask it in https://github.com/steam-forward/node-steam-forum, please do not open an issue here. Issues are only for bugs and feature requests.

Installation

npm install steam-tradeoffers

Usage

Instantiate a SteamTradeOffers object...

var SteamTradeOffers = require('steam-tradeoffers');
var offers = new SteamTradeOffers();

...then setup session and WebAPI key:

offers.setup({
  sessionID: sessionID,
  webCookie: cookies,
  APIKey: webAPIKey
});

You can obtain session information with node-steam and its plugin steam-weblogon.

Demo

A demo bot exists that also serves as a donation bot.

Source code (based on the storehouse.js example).

Examples

You'll need to install node-steam, steam-weblogon, and steam-web-api-key in order to run the examples.

The storehouse.js file contains an example of handling incoming trade offers.

The offerbot.js is an example of making a trade offer.

On first launch both of the examples will 'crash'. Check your email for Steam Guard code and edit an example file to add it, then run it again.

Please read the FAQ before creating an issue about examples.

Methods

options param of all methods is just an object. All callbacks supplied with Error as the first argument or null if no errors occured.

setup(options)

As noted above, this method is used to setup a web session and other settings. If you want to operate with trade offers right after startup, do it after calling this method.

Options:

• sessionID is a valid web session ID.
• webCookie is an array of cookies.
• APIKey is a Web API key for the account you use to trade. API key of another account won't work.
• requestOptions (optional) is a request options object. You can use it to configure timeout, proxy, etc. All available options are listed in request docs. This library uses some defaults:
  • timeout is a number of milliseconds to wait for Steam servers to respond. Default is 30000.
• DEPRECATED timeout (optional) is a number of milliseconds to wait for Steam servers to respond. Default is 30000. More information about timeouts can be found in request docs.

sessionID and webCookie can be acquired using node-steam with the node-steam-weblogon plugin. APIKey can be obtained using node-steam-web-api-key.

loadMyInventory(options, callback)

Loads your inventory for the given app and context. For example, use 440 and 2 for TF2 and 570 and 2 for Dota 2. If success the second argument to callback will be an array of item objects and the third argument will contain raw inventory objects, not merged with descriptions but still concatenated from multiple inventory pages.

Options:

Options:
