Hello joto,
Please help me, i bought 86 tf2 keys from the bot and i cant accept the trade. the message always showed error 25.
So i found an answer from other forum that "Usually error 25 it's related to having reached the limit for sent trade offers. If I remember well you can send a maximum of 3 trade offer to the same person without the other to accept, and you can have a total of 30 open trade offers."
So, how to make offer partilally from your bot?
I want to make it 30 keys / trade.
Pls help me to fix it,

Thank you
then check your steam chat.

It probably means you do not have the inventory space to accept the keys? Do you have tf2 premium?

Also, try to start/quit tf2 to refresh your Steam inventory.
