!add commandIn order to have your bot to start trading, you will need to tell your bot what items to buy/sell/bank by adding the items to the pricelist through Steam Chat. The command that you will use is !add command.
You can just copy the item full name from Backpack.tf, and send to your bot. Example:
!add item=Max's Severed Head!add item=Taunt: The Schadenfreude!add item=Terror-Watt Stately Steel ToeJust make sure to not put a space between the item and the equal sign (=). You can add other listings settings parameter(s) if needed.
Example:
!add item=Max's Severed Head&max=3===
There are two ways of obtaining the sku of an item. You can use the marketplace.tf method or you can use the !sku command
Example 1:
sku: 459;5;u17!add sku=459;5;u17Example 2:
!sku Specialized Killstreak Festivized Australium Tomislavsku: 424;11;australium;kt-2;festive!add sku=424;11;australium;kt-2;festive===
name or defindex parametersExample:
!add name=Tour of Duty Ticket OR!add defindex=725 (no need to add sub-parameter since this is the default).!add name=Tour of Duty Ticket&craftable=false OR!add defindex=725&craftable=false!add name=Pyro's Beanie&quality=Vintage OR!add defindex=51&quality=Vintage!add name=Silver Botkiller Minigun Mk.II&quality=Strange OR!add defindex=958&quality=Strange!add name=Smissmas Saxton&quality=Unusual&effect=Pyroland Daydream OR!add defindex=31089&quality=Unusual&effect=Pyroland Daydream!add name=Tomislav&quality=Strange&australium=true OR!add defindex=424&quality=Strange&australium=true!add name=Tomislav&quality=Strange&australium=true&festive=true OR!add defindex=424&quality=Strange&australium=true&festive=true!add name=Tomislav&quality=Strange&australium=true&killstreak=3 OR!add defindex=424&quality=Strange&australium=true&killstreak=3!add name=Festive Black Box OR!add defindex=1085If you want to add Mann Co. Supply Crate Key with name parameter, it will list out all possible key defindexes from the tf2 schema. Please choose the one at the top with the name Decoder Ring and use !add defindex=5021.

If you want to add a stock weapon (such as Scattergun, Minigun and etc), there are two defindexes for stock weapons. You only need to use the one with Upgradeable_TF_WEAPON_NAME and use that defindex.

Festive and Festivized are two different things. When adding a Festive weapon, please include Festive in the item name (oh and yes, the item defindex is also different), but if Festivized, you need to add the sub-parameter festive=true.
If you want to add Name Tag or Non-Craftable Name Tag, you will need to use the correct defindex, which is 5020 instead of 2093. This bug can not be fixed unless Team Fortress 2 updates its schema to remove the wrong defindex.

Max's Severed Head for a max of 3 with autoprice enabled”162;6)!add sku=162;6&max=3 (no need to add the other this since they are all default).///
Strange Australium Stickybomb Launcher for 23 keys”207;11;australium)!add sku=207;11;australium&intent=sell&sell.keys=23&buy.metal=0To add items in bulk you will be using the !addbulk command. It allows you to use the same item identifying and listing setting paramters as using the !add command.
The syntax is as follows:
!addbulk item_one
item_two
item_two
Let’s look at an example:
!addbulk sku=5021;6&intent=sell
name=Tomislav&quality=Strange&australium=true
defindex=424&quality=Strange&australium=true&festive=true
As always, any listing setting parameters you don’t specify are using default values.
sell.metal parameter.autoprice=false if you’re about to manually price the item.Continue: Updating an item or multiple items
