How do I add someone else's items to a trade? I know how to add my items, but how do I add my items?

How do I add someone else's items to a trade offer? I know how to add my items, but how do I add my items?

I've tried changing offer.addTheirItems, but it doesn't seem to work. All it does is give me an error

 

```

function sendKeysSell(link, amt) { 
    try {
        manager.loadPartnerInventory(440, 2, true, (err, inventory) => { 
            if (err) { 
                console.log(err);
                return;
            } 
            let offer = manager.createOffer(link);
            let keys = inventory.filter(item => item.market_name == 'Mann Co. Supply Crate Key');
            let keyAmt = keys.slice(0, amt);
            offer.addTheirItems(keyAmt);
            offer.send((err, status) => {
            if(err) { 
                console.log(err);
            } else{
                console.log(status)
            } 
        }); 
        }); 
    } catch (err) {
    }
} 

function clearFile() {
fs2.truncate('data.txt', 0, function(){
    console.log('\nDATA.TXT FILE CLEARED\n')
});
}

```

You have to load your partner's inventory and add items from their inventory.

[mistathiccums]

do i also have to load my inventory? even if I don't want to add any of my items

function sendKeysSell(link, amt) { 

    try {
        
        offerSell.loadPartnerInventory(440, 2, true, (err, inventory) => { 

            if (err) { 

                console.log(err);
                return;

            } 
            let offerSell = manager.createOffer(link);
            let keys = inventory.filter(item => item.market_name == 'Mann Co. Supply Crate Key');
            let keyAmt = keys.slice(0, amt);
            offerSell.addTheirItems(keyAmt);
            offerSell.send((err, status) => {
            if(err) { 
                console.log(err);
            } else{
                console.log(status)
            } 
        }); 
        }); 
    } catch (err) {
    }
} 


// This still isn't working, I'm not sure what else to do.

The only thing i can think of is that there are untradeable items in that inventory, and that the bot is selecting the untradeable items resulting in an error, how to fix?

[Dr. McKay]

No, you only need to load an inventory that you want to add items from. You don't even technically need to load it if you already know the IDs of the items you want.

There's not a lot I can do to help you with an error if you don't tell me what the error is.

So I have this function called "sendKeysBuy" that works perfectly fine, but the second function "sendKeysSell", it give me this error " ReferenceError: offer is not defined

function sendKeysBuy(link, amt) { 
    try {
        
        manager.loadInventory(440, 2, true, (err, inventory) => { 
            if (err) { 
                console.log(err);
                return;
            }
            let offer = manager.createOffer(link);
            let keys = inventory.filter(item => item.market_name == 'Mann Co. Supply Crate Key');
            let keyAmt = keys.slice(0, amt);
            offer.addMyItems(keyAmt);
            offer.send((err, status) => {
            if(err) { 
                //console.log(err);
            } else{
                //console.log(status)
            } 
        }); 
        }); 
    } catch (err) {
    }
}

function sendKeysSell(link, amt) { 

    try {
        offer.loadPartnerInventory(440, 2, true, (err, inventory) => { 
            if (err) { 
                console.log(err);
                return;
            }
            var offer = manager.createOffer(link);
            let keys = inventory.filter(item => item.market_name == 'Mann Co. Supply Crate Key');
            let keyAmt = keys.slice(0, amt);

            offer.send((err, status) => {

        }); 
        }); 
    } catch (err) {
        console.log(err);
    }
} 

[Dr. McKay]

You need to call manager.createOffer before you try to call loadPartnerInventory on that offer.

[mistathiccums]

Then i get the error "TypeError: callback is not a function"

[Dr. McKay]

Please check the docs. loadPartnerInventory doesn't have a tradableOnly argument.
