Invalid Trade-URL

The moment you enter trade URL, we are checking if your Steam account can accept trade offers. That's done to make sure we can send you the skin you've earned.

If you see an error saying "The trade link is invalid", it means there's something wrong with your Steam account. It's not opened for trade, so we couldn't have established a connection.
Please check those:

Steam Guard
If it's not enabled, Steam may block your account from receiving trade offers.

Steam Privacy Settings
You need to have your inventory settings set to Public to accept trade offers from us.

Check why you can't trade
You need to be logged in to your Steam account on your device, so Steam could check your account and explain why you are not able to accept trade offers.
