# Going live

> When your integration handles every outcome and works in the sandbox, we move you to production together.

* Every outcome handled: completed, failed, cancelled, expired quote, insufficient balance, open amount.
* Webhook signatures verified over the raw body; events deduped by id; polling fallback in place.
* Amounts handled as decimal strings end to end.
* Retries resend the same `transaction_id` and body; one `transaction_id` per end-user payment.
* Base URL switched to `https://api.rampapay.com/v1` — same paths as the sandbox.
* Production key stored as a secret, server-side only. Rampa issues it; it never works in the sandbox, and vice versa.
* Real USDT top-ups on your agreed chain, sent to your production top-up address and credited automatically once they confirm.
