Introducing NESVRA Sandbox: Build without limits

Every operator we talk to says the same thing about integrating a new payments provider: the hardest part isn't the API, it's everything around it. Getting test credentials, simulating edge cases, understanding what a failed payout actually looks like before it happens in production. Today we're opening the NESVRA Sandbox to fix exactly that.

A sandbox that behaves like production

Most sandboxes are a thin, optimistic slice of the real system. Ours isn't. The NESVRA Sandbox runs the same routing, screening and ledger logic as production, just against simulated money. You can trigger delays, holds, failed KYC checks and provider timeouts on demand, so your integration is tested against reality instead of the happy path alone.

• Instant sandbox API keys, no approval queue
• Simulated delivery across every rail: bank, mobile money, cash pickup, crypto
• Deliberately triggerable failure states for on-hold, failed and refunded transfers
• Full webhook coverage so your status handling is tested before go-live

Built for how engineering teams actually work

You can spin up a sandbox account without talking to sales, wire it into CI so payout logic is tested on every pull request, and promote to production with the same integration code — we don't force a rewrite when you flip the switch. Documentation ships with runnable code samples in five languages, and every response includes the exact fields you'll see in production.

"We cut our integration timeline from six weeks to four days by testing against a sandbox that actually mirrors production behavior."

The sandbox is live today for every developer account. If you're already building on NESVRA, your existing API keys work — just switch the base URL. If you're new, sign up and you'll have working test credentials in under two minutes.
