There are two ways to see Rach working before you go live.

​
Build against the sandbox

Every account gets test keys (test_sk_… for Payments, rach_sk_test_… for CaaS). They hit the same API as live keys, but on testnets — no real funds move. Create a checkout, open its hosted page, receive a webhook, and wire your integration end to end. What the sandbox covers, network by network, is in Environments. Base, Arbitrum, Avalanche, Celo and XRP have no testnet in the sandbox; their behaviour is identical to the networks that do.

​
Book a guided demo

For a tour before you integrate, ask for a demo through Contact sales on rach.finance. A Rach team member walks you through a live, fully populated workspace:
1

The dashboard

One overview across products — collections, balances in USDT, USDC and local currency, and activity over time.
2

Taking a payment

A checkout created from the API, the hosted pay page with its network choice, and a payment moving from detected to confirmed.
3

Getting paid out

Balances, settlement accounts and a withdrawal from start to finish.
4

Running it as a team

Roles and permissions — what an owner can do that a viewer cannot — API keys and webhooks.
The demo workspace is isolated from real customers and holds no real funds, so you can ask to see anything, including what happens when things go wrong.

​
Then go live

When you are ready: complete verification in the dashboard, switch to your live_sk_ key, and point your webhook URL at production. Nothing else in your integration changes.
