Skins deposits for marketplaces and trading platforms
Take skins in, credit users on your platform, and send skins out from the same USD balance. Built for platforms that pass our review.
Approval needed. This is a restricted category in our Acceptable Use Policy: it is allowed after our written approval and extra checks during verification.
Trading platforms live on liquidity. Users want to bring items in quickly, see a fair value straight away, and leave with items when they choose. SkinsFlow handles both directions from one account: deposits of CS2, Dota 2 and Rust items, and skins bought from our market and sent to any trade link.
Deposits are valued the moment the user's inventory loads, credited to your balance in USD after 2.5%, and announced to your backend with a signed webhook. Steam Trade Protection is tracked for you, with signals about the user's account so you can decide when to release a protected deposit early.
Skin marketplaces and trading platforms are a restricted category in our Acceptable Use Policy. They need our written approval before going live, and we run enhanced checks during verification. Platforms where third parties sell to your users, or that cash out balances for others, are not supported without a separate written agreement.
Restricted category: written approval and enhanced due diligence before going live. Payment services, cash-out for third parties and letting other sellers take payments through your account are not allowed without a written agreement.
The problem
What gets in the way today
Slow, manual deposits
Bots, queues and manual pricing make deposits slow and error-prone. Users leave before their items arrive.
Trade reversals
Steam Trade Protection lets users pull items back for up to 7 days. Without tracking, you credit too early and lose the items.
Two systems for in and out
Taking items in and sending items out usually means two providers and two balances to reconcile.

FAQ
Questions, answered.
Can I use SkinsFlow for a trading platform?
Yes, with our written approval. Skin marketplaces and trading platforms are a restricted category in our Acceptable Use Policy, so we review your business, licences where they apply and your policies before you go live.
Can I send skins to users?
Yes. Buy items from our market with your balance and send them to any Steam trade link, one by one or in batches. The price is shown before you buy.
What is Steam Trade Protection?
Steam can hold traded items for up to 7 days and return them to the customer in that window. SkinsFlow tracks every protected payment: it is credited automatically when the hold ends, or right away if you release it early because you trust the customer. If items go back after an early release, the amount comes off your balance and your site is told.
Is case opening or item betting allowed?
Not on this path. Games of chance where items or their value are staked are prohibited unless fully licensed, and even then need separate written approval.
What does it cost?
SkinsFlow charges 2.5% of each credited deposit. Market purchases are paid from your balance at the price shown. Volume pricing is available for established platforms.
How do I get the money out?
Request a payout from your dashboard by crypto, SEPA, ACH, PayPal or Revolut once your business is verified, from $20. You can also spend your balance on skins from our market and send them to anyone with a Steam trade link.
