You’ve placed your order. What happens next depends on where you bought.

​
Exchange purchases (StockX, GOAT)

The simplest path. The platform authenticates every item before it ships to you.
1

Place a bid or buy at the ask

Complete the purchase on the marketplace.
2

Platform authenticates

The seller ships to the platform. They verify condition, size, and authenticity.
3

Ships to you

Once authenticated, the item ships directly to your address.
No extra authentication needed. If the item fails verification, the transaction is cancelled.

​
eBay purchases

eBay has two levels of protection. For sneakers over $100, Authenticity Guarantee routes items through a third-party authenticator — similar to StockX/GOAT. Below that, you’re covered by Money Back Guarantee (return if not as described).

​
P2P purchases (Depop, Mercari, Reddit, Facebook, Grailed)

No middleman. You’re buying directly from the seller.
1

Buy the item

Complete the purchase on the platform.
2

Receive and inspect

Check the item against the listing photos. Verify SKU, size label, and condition.
3

Authenticate if needed

For high-value items, submit photos to LegitApp before selling. See Authentication.
For international purchases or when you want inspection before committing, use a forwarding service.

​
After receiving

Once you have the item, sell on the platform with the best bid. Log both trades in Portfolio to track your P&L.
