Steam Trade Offers for Node.js

Steam Trade Offers for Node.js

Allows you to automate Steam trading using trade offers in Node.js. It was designed with node-steam in mind, but does not depend on it, so you can use it separately if you can supply it with session information. Some of the methods of the library are wrappers for Steam Web API.

Note: By using this library you automatically agree to Steam API Terms of Use

Installation

npm install git://github.com/Alex7Kom/node-steam-tradeoffers.git

Usage

Instantiate a SteamTradeOffers object...

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

...then setup session:

offers.setup(sessionID, cookies);

• sessionID is a valid web session ID. In node-steam, you can use the webSessionID event to get it.
• cookies is an array of cookies. In node-steam, you can use the webLogOn method to get it.

This setup will automatically register and retrieve Steam API key for you.

Methods

All callbacks will be supplied with error as the first argument or null if no errors occured.

loadMyInventory(appid, contextid, 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. The second argument to callback will be an array of item objects in case of success.

loadPartnerInventory(partnerSteamId, appid, contextid, callback)

Loads your partner inventory for the given app and context.

makeOffer(partnerSteamId, message, itemsFromMe, itemsFromThem[, callback])

Makes a trade offer to the partner. itemsFromMe are the items you will lose in the trade. itemsFromThem are the items you will receive in the trade. itemsFromMe and itemsFromThem both are arrays of item objects that look like this:

    "contextid": 2,
    "amount": 1,
    "assetid": "1627590398"
}

If success the second param to callback will be an object with tradeofferid of the newly created trade offer.

getOffers(options, callback)

getOffer(options, callback)

The first method loads a list of trade offers, and the second loads just a single offer. options is an object of input params listed on the page Steam Web API/IEconService. The second argument to callback will be an object that Steam Web API returns. The only thing to note is that the wrapper adds a property steamid_other with the SteamID of the trade partner to each CEcon_TradeOffer object in received trades.

acceptOffer(tradeofferid[, callback])

cancelOffer(tradeofferid[, callback])
