Outpay USDC Payments FAQ for Merchants and Developers
Get concise answers about Outpay custody, Base and USDC support, API integrations, payment links, webhooks, refunds, and beta readiness.
Does Outpay custody funds?
No. The implemented flow sends USDC directly to the merchant's registered payout wallet — see settlement.
Which networks and currencies are supported?
Native USDC on Base mainnet only. Other currencies and networks are not verified — see supported networks and assets.
Are SDKs available?
No official SDK package is published for any language. Use the REST API with server-side fetch, cURL, or another HTTP client — see integration examples.
Can I refund a payment?
No. There is no refund endpoint or automatic refund flow — see payments — not implemented.
Is v0.1 production-ready?
Not verified. Outpay's own release notes state the payment-verification pipeline is still undergoing audit remediation — see system status.
Does a success redirect prove payment?
No. Use a verified checkout.paid webhook or a server-side status read — see do not trust the redirect.
