DigitalOcean is fine. I'd recommend them more now that they've dropped their prices than I would in the past. If you're going with a VPS then you need to read up on security so you don't get pwned. You probably want at least 2 GB of RAM. 1 GB might work but keep in mind that it also needs to support the entire OS too. On a reputable host your files are safe. You don't need to encrypt them unless you're really paranoid, and if you do go that route you can't store the key on the server or it'll defeat the purpose.

Sure, just load two inventories and add two items from different games. Change the amount property on the item. For example: manager.getUserInventoryContents(steamID, 753, 6, true, (err, inv) => { if (err) { throw err; } let gems = inv.filter(item => item.market_hash_name == "Gems"); let item = gems[0]; item.amount = 300; offer.addMyItem(item); });

Don't.

The bot thinks this because it's true.

You never need a trade URL to get an inventory. Just use getUserInventoryContents to get an inventory.

You aren't using async properly. You need to call getInventoryContents inside of the webSession event, after you call setCookies.

No. You can't get private inventories under any circumstance.

The partner parameter in the URL is the account ID of the user. You can use community.getUserInventoryContents("[u:1:" + accountid + "]", . . .)

Who's "the" user? The currently logged in user? playingState A friend? user

Yes, you need to own CS:GO.

Does your bot account own CS:GO?

This is what poll data is for.

I don't know, sorry.

You would need to use node-globaloffensive for that.

I dunno. Maybe Steam has a limit, maybe it doesn't. Why don't you find out?

You're adding an event listener named getTradeURL, not calling a method. community.getTradeURL(...

I don't believe there's a limit on how many games you can "play" at once. I don't know why you'd specify the same game multiple times, but I have no idea what the result would be.

I have not.

Looks like a Steam bug.

You're doing async wrong. You need to put your postGroupAnnouncement call into the webSession event (which is also misspelled, you're missing a capital S) after the setCookies call.

What happens if you don't mark the bot online?

That's pretty interesting. I've never seen that before. What happens if you make your bot go online with setPersona? Although that will make you appear in-game.

offer.data('cancelTime', null); should be right. Maybe try using 0 instead of null?
