Test vs Live

Sandbox and production — the key prefix decides which.

Both Rach products have a sandbox and a production environment. You don’t change your integration to switch — you swap the API key. The key prefix is authoritative.

Product	Sandbox key	Production key
Payments (Gateway, WaaS, Swap)	test_sk_…	live_sk_…
CaaS	rach_sk_test_…	rach_sk_live_…

Payments sandbox

test_sk_ keys use testnet addresses — no real funds move and no on-chain confirmations are required. The environment is stamped onto every checkout and wallet operation at the moment the request is authenticated, so it can’t drift mid-flow.

CaaS sandbox

rach_sk_test_ keys run in sandbox mode: every B2B call returns an immediate SANDBOX_SIMULATED success without touching the blockchain or debiting your treasury — ideal for integration testing and CI.

Going live

1. Build against sandbox

   Wire up your integration end-to-end with the test_* key.

2. Swap the key

   Point production at the live_* key. Nothing else changes.

Use the same base URL in both environments — only the key changes.
