I wanted to withdraw some TF2 Keys and Dota 2 keys, but it's says Inventory is full or API is down or something, but I'm sure that my inventory isn't full, but when I try to deposit a game (Payday 2) it worked just fine.
Please help

I can't say if it's really an API problem. Please try to withdraw TF2 keys and Dota2 keys separately. Then we may find out which item(s) is causing it.
