Sandbox testing

Getting Sandbox access

Sandbox credentials (API Key, API Secret, Webhook Secret) and the test API root {baseUrl} are issued by sales or operations—there is no self-service signup on this website.

Suggested checklist

1. POST /v1/payments with Sandbox credentials for a small test amount.
2. Send the requested token on the test network to the returned address (often USDT on Nile / Shasta).
3. Poll GET /v1/payments/:paymentId until status is PAID (or watch confirmations increase).
4. Confirm your notifyUrl receives payment.paid and signature verification succeeds.

Notes

• Sandbox and Production keys, databases, and chain settings are fully isolated—never mix them.
• Obtain test TRX from a faucet when the network requires TRX for transfer fees.
• Public docs exclude internal debug endpoints—do not commit testnet secrets to public repos or client bundles.
