Get your API keys

Where to find your Payments and CaaS API keys.

Rach has two separate products, each with its own API key, obtained from its own dashboard. The keys are not interchangeable — a Payments key returns 401 on CaaS and vice-versa.

API keys are secrets. Keep them on your backend only — never in a browser, mobile app, or git. Rotate a key immediately from the dashboard if it leaks.

Payments API keys

Used for the Crypto Gateway, WaaS and Swap. Keys are sent in the X-API-Key header and are prefixed test_sk_ (sandbox) or live_sk_ (production).

1. Open the Payments dashboard

   Sign in at payments.rach.finance.

2. Go to Developers → API Keys

   Copy your test and live keys, or rotate them if needed.

CaaS API keys

Used for the CaaS B2B endpoints (/v1/users, /v1/transfers, /v1/fx, /v1/swaps). Keys are sent in the X-API-Key header and are prefixed rach_sk_test_ / rach_sk_live_.

1. Open the CaaS dashboard

   Sign in to your CaaS dashboard.

2. Go to Developers → API Keys

   Generate a key, choose test or live, and copy it.

Which key goes where

You are calling…	Base URL	Key prefix
Gateway / WaaS / Swap	https://api.rach.finance/api/v1/	test_sk_ / live_sk_
CaaS (/v1/users, /v1/transfers, /v1/fx, /v1/swaps)	https://api.rach.finance/caas/api/v1/	rach_sk_test_ / rach_sk_live_

Both go in the X-API-Key header. See Authentication.
