Sandbox test data


QRs	Pay only QRs from `POST /sandbox/qr-codes`: the QR network’s test environment refuses any other (`rejected`, `QR_REFUSED`, nothing reserved). Keep amounts small, Bs 10–100.
Price	The QR network’s test price, plus your margin.
Per-payment cap	Bs 1,000.00. Above it you get `422 AMOUNT_EXCEEDS_PROVIDER_LIMIT` with `max_amount`.
Chain	Tron Shasta testnet. the sandbox test token (contract `TYR7yDZAns63L8Cmu4EyPPxDgktq9sguvB`) stands in for USDT: send it, never real USDT, to your sandbox top-up address. It has 2 decimals, and each token is credited as 1 USDT. Add it to your wallet as a custom token to see it; your wallet may show it under its own name.
Faucet	`POST /sandbox/faucet` sends test tokens to your own wallet. 100.00 per request; 1,000.00 and 10 requests per 24 hours; 1,000.00 per receiving address per 24 hours; 60 seconds between requests; and a daily total shared by every sandbox key. It refuses Rampa addresses, including your top-up address. Need more? Ask us.
Top-ups	Send faucet tokens from your own wallet to your top-up address, as you will in production: a real deposit, with its `deposit.*` webhooks. It is credited automatically once the transfer confirms; `GET /wallets` shows the balance and `GET /wallets/transactions` the top-up.
Data	Sandbox balances persist between sessions and are never reset without notice.
