Skinloop lets a merchant accept CS2 and Rust skins for USD orders without implementing Steam trade handling. Your server creates a hosted checkout, the customer completes the trade on Skinloop, and your server confirms the result.

​
The merchant path

1

Prepare your account

Create a merchant account, copy the API URL shown in the dashboard, and issue a test API key with only the scopes your integration needs. Register the origins used by your success and cancellation URLs.
2

Build the test checkout

Keep the key on your server. Send an integer-cent USD amount and a unique Idempotency-Key to POST /v1/merchant-api/checkouts.
3

Send the customer to Skinloop

Redirect the customer to the returned hostedUrl. Do not treat the browser redirect as proof of payment.
4

Confirm and fulfill

Poll the checkout status or consume the signed webhook. Fulfill only when the authoritative status is completed.
5

Go live carefully

Run the test-to-live checklist, rotate to a live key, verify webhook delivery, and monitor statuses, warnings, errors, and balances.

​
Before you start

  • A Skinloop merchant account
  • The API URL copied from your dashboard
  • A server-side test API key
  • Success and cancellation URLs on registered origins
  • An HTTPS webhook endpoint if you use webhooks
API keys, webhook secrets, and checkout status capabilities stay server-side. Never put them in browser JavaScript, a mobile application, logs, or a repository.
Start with the Quickstart, then read Authentication and API keys and scopes.
